Photoshop CC: Photomerge running slow

I wan't to report a BUG. Setting "Cache tile size" from 4 > 3,2,1 makes Photomerge slow as @£€$.. Just by setting it to 3 will decrease Photomerge's performance by several hundres %. This is a $7 grand computer that chew RAW's like its JPEGS, so I can't say the computer should have issues with increasing this setting just slightly. BTW. This is in Photoshop CC. Photoshop CS6 doesn't have the issue at this workstation.

Cache tile size doesn't have settings of 4,3,2,1 - that sounds like the cache (image pyramid) levels. Cache tile size would be 128K, 132K, 1024K, 1028K.

Also, the cache tile settings and image pyramid settings have not changed in Photoshop CC, or Photoshop CS6.

Could you provide a better description of the slowdown you are seeing?

Oh, sorry.. Tired.. I ment "Cache levels".

Thats strange, cause I've got CC and CS6 installed and its pretty different. CC is several minutes slower than CS6 in Photomerge(Align) when both apps have "Cache levels=2". When I change to standard settings then CC = CS6 in terms of speed.

Photoshop CC slows down, almost freezing when reaching "aligning images" in the Photomerge function. Happends at "Cache level 3,2,1" (with/without image blending). Its just seconds in CS6, even with settings like "Cache level 1".

I also deleted my preferences file and stuff to eliminate "poor file", I've done anything by now :-P I've just got down to the single setting that cause my problem, thats all..

Can anyone else try the difference in PS CC with cache level 4 vs 2? I think it took a minute to process 20x30MB RAW's in PS CS6 with all "cache levels". In PS CC it took a minute in "level 4", and it never finished at level 3,2,1 since it took like 15mins just to get to 5% or something like that.. Here's the setting btw.. Excuse my poor English, both tired and Norwegian.. :-P

Cache level = 1 will slow down MANY things.

We'll have to see if we can reproduce the slowdown - we haven't seen one so far in our performance testing.

And are you sure you're running the 64 bit version in both cases? With images that size, I would expect it to be much slower in the 32 bit version.

Im not dumb mate.. And BTW, "Cache level 3" also freeze PS CC. I know that function will slow things down, BUT, when Chris Cox say nothing has changed, why is there a huge difference between PS CC and PS CS6 then? Must be a BUG, right? Program functions like Photomerge freeze, or never finish.

I always run app in 64 bit. And I've double-checked.

Just wanted to report the bug, I already found what function/setting Photomerge is trolling with, so I just want to report that and maybe hear what other users are experiencing with lower "Cache level".

And in case people think I've got a 5yr old computer and its causing the slowdown:

Motherboard: Asus Rampage IV Extreme
CPU: Intel i7 3690x Extreme (4.6 GHz)
Mem: G.Skill RipJawZ 2400MHz 16GB X.M.P
GPU: Zotac GTX 580 AMP2+
DISK: Kingston HyperX 500/500 R/W
DISK: Raid5 4x2TB e-SATA
+++
Eveything watercooled and overclocked (stable)

I am having the same problem and I have a brand new Alienware (fully loaded) Area 51. CS6 can do a photomerge in under 15 seconds on the same files with this machine. But in PS CC everything freezes on the "blending' sequence. It is clearly a bug. I can use CS6 as a work-around - but then why am I paying for CC?

OK - I just saw the recommendation to set to Cache level 4 and it DID work. Thanks!

We still haven't reproduced a freeze or significant slowdown with cache levels set to 1. What I think we'll have to do is profile it, and see if any part of the process MIGHT slow down, then see under what circumstances that might happen (it's probably something specific about certain images, machine config, etc.).

Good Stan Yeatts!

Chris Cox. Thanks. This is a bigger issue than just 2-3 computers. Several people on http://forums.adobe.com/ have this issue also. Example: http://forums.adobe.com/message/58150...

I recently forgot about this issue and had the problem all over again. I then joined that tread (mentioned above) and went into the details with screenshots and timestamps.

I've had this issues with 2 workstations. Things they have in common is: Win7, nvidia card(tried different drivers), intel cpu, asus lga 2011 socket.

People should try setting cache levels from 4 to 2 and report the difference. Please state OS/CPU and GPU. And people who got this problem and wish to fix it, set it to 4 and report back with same criteria.

The difference between PS CCx64 and PS CS6x64 with identical settings and images is >1.5 hrs (see http://forums.adobe.com/message/58150... ). Gotta be a software issue, because thats the difference on same workstation.

I add that we might suffer from other issues now when changing back to cache level 4. Redraw speed and retouching got slower if im not wrong.

Can't you run a diffstat or something on the developer files to check where photomerge changed between PS CC and PS CS6? I really wish Adobe fix this.

Thanks

I got this problem this afternoon for the first time !
I did a lot of photomerge since I got CC but since I installed "levelup" photomerge running very very slow when it tries to align.
i had the cache level at 1.
Now I changed the cache level to 4 and it's ok !
Thank you Aleksander !

I forgot this bug and got the same problem again, now its fixed. Easy to forget :) I made some screenshots and explanations in this thread.
http://forums.adobe.com/message/58150...

I belive this is a software bug in Adobe. Comparing PS CCx64 and PS CS6x64 with identical cache level (2), history states (50) and tile size (1024) gave me a huge difference in speed. PS CS6x64 finished 15x 25Mpix in 5minutes, PS CCx64 finished in 1.5hrs(sometimes it crashed). Ive tried on 2 different workstations, same issue.

Anyone who can write better English than me, please send a bugreport to adobe if they don't see this thread. There have been no changes to photomerge since this topic started, so they have done nothing to this bug yet as far as I know.

Please state what OS/GPU/CPU you have since that could make or break the issue.

Issues occurs with these computers. Same identical issue, files and PS CCx64 vs PS CS6x64.

Windows 7 home pro. LGA 2011 socket. Intel i7 3690x. Zotac nVidia GTX580 AMP2+. 16GB G.skill ripjawz. PCI-e SSD OCZ, Raid5 4x2TB velociraptors.

Windows 7 home pro. HP Laptop. Intel i7. 8GB RAM. nVidia(..), SSD.

Having exactly the same problem. When it gets to "Blend Selected Layers", it just grinds to a halt. Had no problems at all prior to the latest update.Tried processing exactly the same images in CS6 and it took only a few seconds. Definitely a lot of bugs with this latest update, as this is about the 5th new problem I've found.
