Photoshop: CS6 Slow compared to CS5.1 with large files

  • Problem

  • Solved
PS CS6 has a lot of enhancements and great features. it launches very fast, and the control is very responsive and smooth.

although i am experiencing some speed issues with very large files. compared to CS5.1, where i don't have any of these issues.

the files are PSBs, 9000x8000px, 80+layers, RGB, 8bit

i have the same performance settings for both, cs6 and cs5
i am working on MAC PRO, 16GB ram, SSD scratch, 2TB raid, Radeon HD 5770, Snow Leopard.

the main issues i have are:

- no refresh when i move the curve on adjustment layer. the refresh comes after i let go.
- jagged pan
- extremely slow moving of layers and layer groups, even if they are with smaller dimensions (800x400pix)

again, working with files with less layers or smaller dimensions is very fast.

thanks for your help and support!

IMPORTANT:

I was just working with my fresh install and I have to say the problem goes away to some degree after several minutes of working with a composition...it seems like it is progressively cache-ing the document. Try zooming all the way in and then all the way out of a document when you first open it. For me, it works quite well like it is cache-ing the entire thing...almost like in CAD when you regen once zoomed in and once zoomed out.

I dont remember this behavior on cs5.1, but now that i know how to get around it, its not a "deal killer".

Seeing similar issues here with CS6 and large fiels with lots of layers.

Turning off thumbnails or switching to the Channels palette help responsiveness....but overall it seems a bit more sluggish than CS5 did.

Same problem here. Maybe not as bad as some others but I do notice cs6 being slower with large files. Its usable but i wish it was a bit more responsive. Unfortunaly I'm always working on images between 3-6g in size...

I especially notice it with the Transform tool. Nudging and trasforming is slow in general

Also as someone else mentioned. When i do colour adjustments I cannot see the adjustments realtime. It's not until i let go the arrow that it refreshes the colour. Before in Cs4 if i moved the arrow on the slider it would show me the adjustments realtime.

So now that many users who are experiencing this issue have posted their System Information, what happens next? Does Adobe acknowledge that many power users who are working with large files are experiencing this issue or should we just continue to believe that it's somehow related to how our systems are configured? I Googled around earlier this afternoon and found a few other threads and reviews that mirror the exact sentiment from this forum.

Are there at least plans to test and examine the issue in an attempt to remedy the issue?

Chris,

So Adobe is aware of a "thumbnail problem" within PS CS6?

Is this being addressed for a future update?

That was already discussed in a couple of other topics. We are pursuing fixes to the issue. In the meantime slowdowns when moving a lot of layers can be worked around by disabling thumbnails in the layers palette preferences.

Glad to hear it. But to clarify, turning off Layer Thumbnails *slightly helps* increase the speed and performance but it's still far slower than CS4 and 5 to work with layer groups and even to open, save, close and zoom in/out of a larger file that contains many layers.

Turning off the Thumbnails fixed the speed issue with large files and working with layer groups for me. HOWEVER that only goes to show you where the problem might be. I certainly hope Adobe takes this serious and fixes it ASAP. BECAUSE turning off the thumbnails is NO SOLUTION I cant work without the thumbnails =(. So until this gets fix I have to deal with this issue unfortunately =(.

I sure hope Adobe considers turning off the thumbnails a "temporary workaround".

Have 2 machines, Tower and Laptop, 6 i significantly slower than 5. A lot of lag just changing tools

Side note .. the icons all look like stepping back to system 7, any way to make them like 5?

Hey all, I've been experiencing all the same problems as you've described. I usually work with 100s of layers and a good dozen of folders. Like all of you, CS6 seems much slower than CS5 to me.

Some good news, I just tweaked my File Handling preferences and adjusted the Cache Levels from 4 to 2. It really seemed to help! Screen redraws much faster and I don't get as much of a delay while moving things around.

Still want to turn the thumbnails on in the layers palette and still not sure why Photoshop is unresponsive for a bit at times when I switch b/w other programs (Safari in most cases).

Allan has a great point that I consider a bit of a breakthrough (other than layer thumbnails) in making CS6 a little faster. I changed my cache levels to 2, re-started and did find it quite a bit faster. Not quite CS 4 or 5 fast, but closer and more useable with large, multi-layered files.

Thanks Alex, but I can't take credit, it was that guy above who noted it. It just worked for me to some degree too.

I still have one or two specific files that I could video with my phone and upload to Youtube or something and post for Chris's review, he'll see what we mean in action. I don't beleive anyone has done that yet.

I think it will become abundantly more clear what we mean if he can see exactly what is happening

That link is an example of the delays that I am still experiencing, even after changing the cache levels to 2 (vs 4) and turning off layer previews. Its a lot better for me in the above video with those two settings changed, but it could be better.

Alex, can you tell me if this is the same type of thing you are experiencing?

Definitely looks like the same issue. I have to say lowering the Cache levels to 2 has really helped. Before that, the opening of and moving of layers on larger, more layer-rich files was painfully slow. Like full minutes (2-3) to open and 10-15 seconds to move a layer group like 10 px.

OK, I need to get a copy of that file so we can try to reproduce that slowdown. That could be video driver related, or could be something internal to Photoshop. I won't know until I can reproduce it and profile it.

I experienced the exact same problem which is why I went searching for known issues and ended up here.

Files in the 60MP range with several layers is no problem but with files larger than this (90000x6000 and larger) with many layers CS6 becomes irritatingly slow. Moving layers and groups of layers works like a turd.

My system is a MacPro2011 (Octo 2.93 with 48Gb main memory, ATI5770 running the files from a RAID5 SSD system). Can post exact config when I am behind the 'big machine'.

Certainly would be appreciated when this gets fixed, I need to be able to work fluidly with files of this size.

I am experiencing extreme slowness as well. I had CS5 on the same exact machine and it ran MUCH faster than CS6.

It is virtually impossible to work quickly/efficiently on CS6 now. Is Adobe still looking into this?

I have been experiencing extreme lag when moving groups of layers as well. Instead of turning off layer thumbnails, pressing tab to hide all panels before moving groups allows me to avoid most of the lag, although even this is slower than cs5 at the same task. Having the transformation values enabled seems to negatively impact the speed of moving groups and individual layers as well.

Maybe I didn't explain well, something can run as fluent at 80% load as it does on 10%, but no need to say the first one is suboptimal. It becomes easier to reach 100% and show slowdowns for a broader number of hardware. Only an example. And yes I know that the opposite is also possible, sluggish at either 80% or 10%, but then we would have been talking about incompatibilities and not simply power as I do.

I use XP SP3. So this is not going to help much because there doesn't exist any official driver for this card beyond version 266. It's just marketing politics that 9600GT is supported but the Mobile version "isn't", upon a guide I just reenabled support editing some flags. I don't know you can try with v.266, or the desktop card, or mobile with vista or seven, or simply another individual setup with similar issues. I'm not urged in my personal case.

Again - you're seeing it take longer to redraw than CS5 did. I'm not seeing that, at all. I do not see a slowdown on any of my systems - thus I cannot diagnose a slowdown using my systems. 80% versus 10% doesn't matter -- on my systems CS6 takes the same amount of time and CPU usage as CS5 did.

If you're using XP, then the GPU settings can't be enabled in Photoshop CS6 - they are always disabled on XP (because we know the drivers don't work correctly, and the OS has bugs that will never be fixed).

Ah ok, so that's the reason I had to input the AllowOldGPU in the registry in order to make it work. Could you give me some insight on what things you detected that don't work on the driver (last version I suppose) and XP? I like tuning my OS and am interested.

We found lots of things, and disabled all GPU usage for XP.
And you used a "use at your own risk" registry entry that was intended for GPU vendors, not end users.
Get Win7, you'll be a whole lot happier.

Thanks for the suggestion but I have my own opinion on post XP windowses. I guess you can't tell or indicate about those XP flaws?
Still slowdowns on CPU mode stand true as I mentioned above. That's something to look at, but don't tell to me, I think I made the definitive decision to stay on CS3.

Hey Chris Cox,

Your not really helping anyone in this thread - do you think we're making this slowdown up? As several people have said, there's a major regression in Photoshop that makes this upgrade, that we've all paid a lot money for, essentially worthless for the kind of work we do. Most of us still have CS5 installed which shows none of these issues.

Turning off layer thumbnails doesn't fix the issue, as several people have mentioned above - at least give us the courtesy of acknowledging this fact and letting us know what we can do to help you fix it, if indeed Adobe intend to. Otherwise we can all just ask for a refund of our CS6 upgrade and stick to using the fully functional CS5.

I am trying to help you. But you seem to assume that everyone sees the same problem you do, and they don't. And you seem to assume that I can solve whatever problem you are seeing without ever seeing it myself.

We know about the layer thumbnail slowdown - so first, you need to eliminate that as a possible cause by disabling layer thumbnails. AFTER that, then see if a slowdown remains, and if so, you need to help figure out why your system is seeing a slowdown that other people don't. What is different about your configuration, your usage, your other apps, your utilities, your preferences, etc.
We can't solve this for you because we're not seeing it.

We can't acknowledge something that we've never seen ourselves. We still don't know whether this is a Photoshop problem, and external problem, or what might be going on.

You are going to have to do some troubleshooting to help narrow down the problem on your system.

Where did anyone assume that everyone has the same problem? Of course we all want a fix but I don't think I somehow have right to one - it's up to you how you assign your development time, we can vote with our wallets if that doesn't suit us.

I have tried everything that's been suggested with no improvement - the fact that this is cross platform issue (OS X & Windows) suggests that it's a fundamental issue with Photoshop on certain PS file (large dimensions, lots of layers, lots of layer effects) - do you have a set of example PSDs that you run your performance tests on?

You assume that other people are seeing a slowdown -- and the vast majority of users are seeing no slowdown. Yes, different people probably are seeing different slowdowns (thumbnails, video drivers, antivirus, etc.).

And we are trying to track down whatever might be causing slowdowns for those people, but we need to be able to reproduce the problem in order to figure out the cause.

The thumbnail problem is cross platform. The rest so far seems to be more platform or system specific -- but people are confusing multiple issues with some global issue that has no evidence behind it.

No, we run our tests with lots of different documents, plus runtime generated documents (for when we need thousands of layers, etc.).

The only fundamental issue seen so far is the layer thumbnail slowdown - which is why we keep asking people to turn off layer thumbnails then test again.

Again: you have an issue, but other people do not see the same issue. So we're trying to work with you to figure out what is different about your system, preferences, or usage to show a slowdown that other people are not seeing.

I have tried turning off items, indeed turning off layers does help however when you have 100+ layeres and you need to move something you often need to move things compared to other layers so turning off layers is not an option!!!!

I use almost the latest MacPro and one of the fastest;

MacPro 2.93 dual processor six core (12 cores) with 48gb of main memory. my work files are on a 6 drive OCZ 256GB SSD RAID5 system and the video card is an ATI5770.

If my machine is underspecced I happily buy new things to solve this however, please tell me what that might be???? somehow I don't think swapping the 5770 for a 5870 or upping memory from 48gb to 96gb or even swapping processors for marginally faster XEONs will make a big difference....

IMO this is something that needs to be fixed, I can hardly imagine Adobe not being able to reproduce this.

BTW CS5.1 does not have this issue.

Again, as you can read here and in other topics - we know about the layer thumbnail slowdown. For a temporary workaround, turn off the layer thumbnails. We're working on a fix.

Beyond that, we have not seen any slowdowns that weren't explained by third party software (plugins, anti-virus, drivers, etc.).

If you have a slowdown after turning off layer thumbnails, then we need more information to reproduce the problem.

I did write turning off layers, not turning off the layer thumbs. I will check whether turning off the thumb does the trick and get back.

My OS is Snow Leopard completely updated. The files I typically have issues with are really large. 9000x7000, 100 something layers and over 4gb large (psb). With smaller files I do not particularly notice a slow down.

I'm having the same problems and it has costed my whole Sunday afternoon doing tests and trying to fix the issue. Just purchased Creative Cloud and didn't have the same performance problems with CS5.

I'm on a 2010 iMac i5 with 8 gb ram, Lion 10.7.4. I've tried different cache settings, turning off layer thumbnails, turning off OpenGL, but nothing helped. Panning is very slow, switching from normal mode to fullscreen with menu mode also lag (also some graphical artifacts for a few seconds). Switching tools also lag. I switch from normal mode to fullscreen mode a lot and use the OpenGL interactive zooming A LOT, I really can't live without the OpenGL zoom mode. It will make my process very slow, which means I will lose time / lose money! Also turning off layer thumbnails is not a solution, it makes the layers very small, very hard to select the layers and hard to see.

I tested it with a website I've designed. 1200x1600 px, 16 mb file with many layer groups, vector shapes and type. PS is completely unusable for me at this stage.

I will need to switch back to CS5 for now in order to get my work done, this is really disappointing and I hope Adobe fixes this very soon!!

Note: Turning off layer thumbnails didn't fix it for me at all.

I saw I had a plugin installed (GuideGuide). I removed it.

I did some more testing with PS CS6 and today it is a lot better, usable but the UX is quite 'not nice' due to the decreased performance (if you are like me and you create UI designs for a living). Same 1200x1600 file with a lot of vector shapes, text and folders. Panning, zooming with OpenGL a lot faster. Moving individual elements was fast, as expected. But moving a group of objects. For example a typical website header (folder) with logo (smart object), 5 buttons (folders with vector shapes and type). Many of these layers had styles applied to it (gradient, stroke, outer glow). I suspect PS has trouble calculating all the styles.

p.s. Regarding performance I'm not talking about the time it needs to calculate a complex gaussian blur, but more like operating the UI. Opening, closing folders. Moving/nudging folders with a lot of layers (this has always been a slight problem, even with older versions).

Moving a group sounds like the known layer thumbnail problem. Can you confirm that you have layer thumbnails turned off?

Chris,

I have been using ps cs6 this weekend on my macbook air extensively and can also confirm that I am seeing a 'jagged' pan (read: slow and choppy) when using the hand tool. When performing a test of the same file with cs5, pans happen smoothly and quickly.

Hiding and showing panels makes no difference.

This machine is a 1.8 i7, 4 gigs of ram, mac osx 10.7.4

The hand tool is just dependent on the video card redrawing part of the screen - so that's a good test.

What GPU?
What machine model?
Does the behavior change if you disable the GPU in preferences?

Hmm, what else might affect that....
Does changing the tile size in preferences change the behavior?

Machine: Macbook Air, Intel 1.8 core i7, 4 gb RAM mac osx 10.7.4. Video card (as listed in PS prefs) Intel HD graphics 3000 OpenGL Engine.

When I disable the GPU in prefs, the pan becomes smoother (but ever so slightly less responsive. By this, I mean that there is a slight delay between dragging with the hand tool and movement. The movement itself is smooth.).

Cache tile size changes don't seem to have any effect.

I have also tried closing all other programs but nothing external seems to be affecting this problem.

Can we assume from this that there is some issue between my Macbook Air's GPU and this problem I am seeing?

Yeah, sounds like the HD3000 may be a bit underpowered to run smoothly.

We'll have to do some more testing, but it really does sound like the HD3000 just isn't up to the task (partly because CS6 uses the GPU for more than CS5 did).

Vector shapes + effects it is!

I have done some more testing with the same website PSD of 1200x1600 px with many folders and layers, comparing PS CS5.1 to PS CS6.

I selected a particular folder consisting of folders, within those folders vector shapes + effects and type. For example a header with a logo and 5 buttons, each button is a folder with vector shapes + effects (outer glow, gradient, stroke).

In CS 5.1 using the move tool dragging the folder around is fast (although not lightning fast). In CS 6 it is a lot slower, and in the case of folders with more elements it was almost impossible to move it in real time (let's say 2 fps compared to 15 fps). Nudging with shift was also slow. When converted the whole folder into a smart object, moving it was blazing fast of course. (logical: Now PS only needs to calculate the x y of 1 object)

So my conclusion is that PS CS6 has trouble calculating (looping through all the vector shapes with effects in them) all at once when moving it. Note that in previous versions this problem already existed, although not as worse as in CS6 (on my system). I did some Flash programming in the past, that's why I used the term 'looping'. If somehow the code can be optimized so it will loop through all the folders/layers/shapes more efficiently, it would solve the problem... But who am I to say this right. :)

The only solution I can think of for now is: Go back to PS CS5.1 and/or buy a super fast Mac Pro with 16 core and 32 gb of ram... as you can understand the latter will not be an option for many people because of the cost.

In my opinion I think the code really needs to be improved.

Well, the thumbnails changed in CS6 (known problem), but the effects didn't.

Vector shapes got more options, but should be the same speed or faster than they were before if you use the same old options. If you add a vector stroke, then it will be slower because it now has more work to do (equivalent to another vector layer).

Please read the previous posts. If you are seeing a slowdown with moving layers - turn off layer thumbnails. Then we'll need more information and you to do some testing to figure out why your system is running slow.

I'm experiencing same issues as described above.

Awaiting a fix.

And I gotta say... the employee responses on this thread are a bit unprofessional. There is usually a specific process to responding to a support inquiry in which exact questions and answers are dialogued. There is a lot of "You assume..." and "Well, most users don't see this issue..." going on which doesn't help anyone.

My advice is to remain transparent, do not engage socially or try to level personally with us - almost canned responses are better at this point when you have very agitated users.

In heated support situations, canned responses tend to make things worse.
(I've seen that go down too many times)

Trying to help the customer understand the situation, and that we're trying to help (even if we can't solve problems instantly), usually helps if they're willing to listen.

Finally had a chance to get back to this problem, installed a new HD from scratch, nothing else on the HD, installed CS6 Photoshop and had exactly the same issues as before.

Tried everything in this thread that was suggested, nothing worked, until...

Setting Cache Level to 2 fixed pretty much everything, no weird zooming behaviour or any of the glitches and beachballing that happend before.

So, looks like that can be a fix - to be honest I've never touched cacheing before on any install of Photoshop and I've been using it since version 2.5 (20 years, wow!) but there you go.

P.S. gotta agree with Sean above, the employee responses on this thread have been very poor indeed - this is an official pro-software support forum, not YouTube comments.

I am experiencing major problems with the speed of Photoshop CS6 with larger files.

I am running it on a brand new (2 weeks old) maxed out iMac (16GB RAM off a solid state drive / 3.4 GHz Quad Core).

I work with files of between 200—700mb (layered). I purchased the new machine and CS6 as CS3 was starting to run slowly on the old iMac. Having parted with the best part of £3.5k I am back where I started!

Please can Adobe respond and let me know what is being done about this, it's driving me up the wall!

I have a brand new iMac Quad Core 3.4GHz i7 / 16GB RAM / Solid State Drive running CS6. Photoshop is incredibly laggy with medium/larger files.

Having spent £3.5k to get a machine and package that would be super fast this is incredibly frustrating and just not good enough. PLEASE SORT THIS OUT ADOBE.

First thing you should do is update to MacOS 10.7.4 to pick up the video driver fixes. (not sure if they'll solve your problem, but Apple did fix a lot)

I've now updated to 10.7.4 but I'm afraid this has had absolutely no effect whatsoever. Still unresponsive on all fronts even down to the mouses right click functionality - works sometimes and doesn't others.

One major thing I have noticed is that my layered file sizes are massively larger than when I was on CS3 - why is this? I have just transferred a file that is 8.24MB file size / 952MB layered on CS 6 on my new mac back to my old mac running CS3 and the size is 8.24MB file size / 206.3MB layered. There seems to be a major discrepancy. Please can you let me know on this?

If a right mouse click doesn't work almost instantly - then something is interfering with events on your system. We've seen a few customers report that their web browser was causing that (and suspect flash).

Check your preferences - if you changed the tile size or cache levels, that would affect the document size in memory. (and file size has little relation to document size, due to compression)

As a small design agency we absolutely rely on Creative Suite for our work and principally Photoshop. Having recently invested in equipment updates and an upgrade to CS6 this is incredibly frustrating, if not potentially damaging to our business that Photoshop simply isn't working.

There is a distinct lack of effort by Adobe to tackle this problem head on. Having spoken with their customer services department there was a very vague attempt to look at the problem that essentially culminated in the sentiment that most of our users are entirely happy with speed. Rubbish!

All of the other core products in CS6 are working well. This is a specific issue with Photoshop CS6 which Adobe are struggling to respond to.

Given the cost of the software, the fact that it is essential to the majority of people who use it professionally, we'd expect a much stronger and more focused response from Adobe.

WHEN WILL THERE BE AN UPDATE TO ADDRESS THE ISSUES THAT ARE DETAILED IN THIS POST?

There can't be an update until we can reproduce the problems and find the causes. So far the only problem that is reproducible is the layer thumbnail slowdown - which has a workaround, and we're testing the fix for.

For the vast majority of users, Photoshop CS6 is working as fast or faster than CS5. But some users are experiencing slowdowns on their systems, and we've been trying to work with them to determine why their systems are showing slowdowns that other people are not seeing, and that we cannot reproduce.

Please do not assume that because you are experiencing a slowdown that all users are seeing the same thing - because they are not. You have a performance problem on your system - let's try to figure out why your system is showing this when other systems do not.

Dear Adobe, please stop saying these problems are 'specific to their systems and/or not widespread and mostly not reproducible'. This isn't coincidence anymore if so many people have the same problems. Do you guys really do some real testing on several types of computers? Do you guys even try to stand in our shoes (in other words understand the users) to understand the problems? There are serious issues with PS CS6 that are certainly NOT related to our systems. Easy to blame others! It's easy to say: "I don't see what you mean, I cannot reproduce the problem, so there are no problems." It could be your are lying (in other words you do know there are problems, but don't want to admit it) or you are just ignorent.

People like us are professional users, who have paid for the software and depend on the software to work properly to get work done on a daily basis.

Yes, we tested on a huge variety of systems, and had thousands of beta testers testing on an even larger variety of systems.

Just because you are experiencing a problem does not mean that everyone else is experiencing a problem. And the evidence is that most people are not experiencing performance problems -- so there is something on your system that triggers a problem, and we need to figure out what that is.

We're users of Photoshop as well - we wouldn't put up with such problems if we saw them -- but we have not seen them.

We're not blaming you in any way - we're trying to help you get to the bottom of the problem, and then see if that cause might be the same on other systems as well.

And it could be that we're telling you the truth and you really aren't helping.

I have turned off the thumbnails in the layer panel. Set the cache to no more than 2 and still with files in the 10000x7000 range with 100+ layers PSCS6 is slow as a turd. Moving a layer takes forever and most annoyingly the program is hardly responding. Movement of the layer has a lag of over several seconds.

As an experiment: go to the view menu, and turn off the Snap item (command-shift-; ). It looks like the complexity of the layers is making "snap to layer bounds" take too long to check against all layer bounds.

Turning snap on or off does not seem to make a difference. I reckon the idea is good but it is not what is causing the slowdown at my system.

The only big slowdown I can see while moving the layer is caused by the snap to layer option. Do make sure you have layer thumbnails turned off, as requested before.

The delay when first clicking appears to be mostly caused by Layer 1 and the pattern fill set to 1% scaling. Scaling and filling that pattern ends up taking a lot of time (more than I think it should, but it's still an extreme case). That's why turning off that layer helps a bit.

There is some delay caused by compositing all the other layers and styles, but it's only about 5% of the total. That one layer and the pattern fill accounts for 90%+ of the time when first opening the file, and when first clicking to move a layer.

hello chris,

i just made some tests as well on my side and created a test file which shows exactly the issues most of us here are seeing. is it possible to share this file with you and also everyone else here, so we can see if we are talking about the same problem.

the file contains a lot of gradients with masks and a lot of multiplied dots in separate groups.

the problems i am experiencing with this particular file are:

- extremely slow moving of groups of layers (test file: white dots group)
- very slow pan
- not immediate redraw when changing adjustment layer (curve, levels, H/S)

the things does improve with thumbs off, but still not usable and very slow. still getting the progress bar when moving bunch of layers (white dots group) and can not follow the movement.
i don't see any improvements turning cache levels to 2, i is getting even worse. turned back to 6 levels.

all this compared with cs5.1 on the same mac, sys info is somewhere in the beginning of the thread. moving the dots on cs5.1 is jagged but follows the movement.

here a link with the file:
https://www.sugarsync.com/pf/D046051_...

everyone else having the sam issues, feel free to download the file and test it on your side.
please give us your results here.

thanks!

Hue/Sat slider changes are instantaneous - regardless of layer thumbnails.
Curves changes are about 20 FPS. I'm curious why that is slow, but suspect it has to do with the curves mouse tracking.

Still, something is very wrong if you're getting a progress bar when working with that document.

i did some precise tests with the white dots and got some surprising results!

moving "white dots" group sum up :
CS6, thumbs on, very slow jagged movement and progress bar.
CS5, thumbs on, acceptable movement slow but not jagged.

CS6, thumbs off, very responsive and fluent movement at 100% zoom or fit to screen.
CS6, thumbs off, zoomed in but not 100%, slower and slightly jagged movement but responsive.
CS5, thumbs off, faster and responsive movement as with thumbs on. (same as cs6)

why the difference between thumbs ON and OFF on CS5? shouldn't be the same speed??

somehow i can narrow it down to the thumbnail problem at the moment.
i realize now that we maybe have different issues with our systems, and also that CS6 needs a lot of resources and it's notthat universal as CS5 was.

and why adobe didn't came up first with the idea of exchanging a file with us so we can examine the issues??

CS5 also had a slowdown due to layer thumbnails, it just wasn't as pronounced as in CS6.

I asked for files and details months ago - the first customer file I got identified the thumbnail issue. But since I can't reproduce any other issues (until Ray's), I can't give you any files that show the issue.

And I've asked repeatedly that you first turn thumbnails off in CS6 to eliminate that known problem, so we can move on to any remaining problems (like the layer snap identified in Ray's file, and the as-of-yet unidentified). If you don't eliminate the known problems, you're just wasting time and throwing off the search for as-of-yet unknown problems.

We've been working on this for months, and trying to get feedback from customers who are actually seeing the problems that we have not been able to reproduce. We really want to see these problems fixed -- but if we can't reproduce the problem, then we can't do much about it. When we ask for more information - we need that information to help identify the cause of the problem.

P.S. I've also been working with you through my vacation and one killer cold (still in progress, which is why I answered posts at 2, 5, and 9 am today).

Just tested with the file given (on PC workstation).

1. Photoshop CS5 took 35 seconds to open the file, Photoshop CS6 took 27.

2. It's not blazingly fast to move layers around in either version, but there's really no obvious difference for me in Photoshop CS5 vs Photoshop CS6. With the image fit to screen (12.5% zoom) I see maybe 4 or 5 updates per second while moving any of the layers around. If anything, Photoshop CS6 may be a hair more responsive. I don't think this is unreasonable performance for moving 64 megapixels around.

3. The screen updated for me in real time in both versions when I move the points on the Curves layer, after perhaps a slight initial delay on the very first movement.

4. Panning at any zoom level is just smooth, and the flick pan settles nicely.

5. Zooming from 12.5% to 100% via the right-click menu resulted in a momentary jump the first time I did it, after some animation had occurred. Subsequent zooms were smooth the whole way.

Honestly, I see no degradation whatsoever - and in fact I see some improvements in Photoshop CS6 vs. CS5 - as viewed on my PC workstation with this test image.

I'm just repeating my reply here from above to ensure it gets attention:

I've now updated to 10.7.4 but I'm afraid this has had absolutely no effect whatsoever. Still unresponsive on all fronts even down to the mouses right click functionality - works sometimes and doesn't others.

One major thing I have noticed is that my layered file sizes are massively larger than when I was on CS3 - why is this? I have just transferred a file that is 8.24MB file size / 952MB layered on CS 6 on my new mac back to my old mac running CS3 and the size is 8.24MB file size / 206.3MB layered. There seems to be a major discrepancy. Please can you let me know on this?
