Many Brushes Lagging After Photoshop CC Update Across All Platforms, Mac and PC

  • Updated 9 months ago
Ever since the rollout of Adobe Photoshop CC, I have noticed a massive lag in many of the brushes, both Default and custom, in my Photoshop CS6 and CC that did not exist before I updated to CC. I tried installing Photoshop on several different machines, including a Macbook Pro, and had the same exact results with brush lag. I went down the troubleshooting list, trying everything, including starting in Safe Mode and resetting my preferences. The problem repeated itself on all systems. Rolling all the way back to CS2 did not help and the same exact problem repeated itself.

The solution I found was to increase the Spacing in the attributes of these lagging brushes past 1%. I thought I would report this very strange behavior as a bug in hopes that it will be patched on the next release.

I also took a video of my solution here: http://youtu.be/bS6tpBXW_OA

Installing CC can't have any effect on older versions.

for me when my brushes lag - I quit Chrome (or other browser) running Flash streaming music sites like google play or pandora. that usually fixes the problem.

Last night I tried installing Photoshop CC on a completely fresh install of the Mac OS (Lion) on a Macbook that's a tier up from the one I listed in my support thread. It still had the same exact issue, so I do not believe google play or pandora or tablet drivers or anything of that sort is the issue, since the setup was bare of any extraneous programs.

If upgrading to CC doesn't affect prior versions, then why did it on my system and other systems that I tested on? The problem was not there until I upgraded to CC.

I tried Photoshop CS6 and CC on these machines and still had the same exact problem on two Windows 8 PCs and a Macbook Pro when the problem was not there before the update. All of these systems are up to date with the latest drivers.

The Spacing solution seems to work across systems so far, so hopefully that solution remains valid for others who might be having this issue.

my experience so far. Doesn't look promising so far when other softwares are working flawlessly on the same system.

Most other users are not seeing a slowdown. You really need to check your system for issues (video drivers, tablet drivers, etc.).

thanks for your reply Chris but there aren't any more recent drivers for my tablet or my graphic card unfortunately.

Various other drawing softwares and the main software I use on this PC, Autodesk Maya, all run fine on that computer so the issue must be Photoshop CC or anything that got installed with it.

Other software doesn't call the exact same APIs. But most people are not seeing a slowdown like this, and we can't reproduce such a slowdown - so logically the problem is something local to your system: a driver, a utility, corrupt fonts (try turning off font preview), or something you may have overlooked.

I have a second computer running Windows 8 but I don't know if I will be able to install Photoshop CC trial on that computer too. Well I guess I could create a different Adobe cloud account

Chris, I've reproduced this bug across four computers now. I'll repaste the specs here for you to see.

I've gone through the entire Troubleshooting guide for Photoshop which disables 3rd party presets, as well as tried running in Safe Mode, which also disables 3rd party drivers. Basically everything you're saying that focuses on 3rd party requirements, I've tested. Here are those specs again on the first three builds, if the details and video I linked before aren't enough:

Processor: Intel Core 2 Quad CPU Q6600 2.40 GHZ
RAM: 8 GB
Operating System: Windows 8 (64-bit)
Graphics Card: AMD Radeon HD 6700 Series
Hard Drive: Samsung 830 256 GB Solid State (where my scratch drive is)
Monitor: 2 X Dell U2410

The PC:
Processor: Intel Core i5 3570K 3.4 GHz, overclocked to 4.4 GHz
RAM: 16GB DDR3 1600 MHz
Operating System: Windows 8 (64 Bit)
Graphics Card: 2 X EVGA Nvidia GTX 670 4GB SLI
Hard Drive: 2 X Samsung 840 Pro 256 GB SSD, Raid 0
Monitor: Apple 27" Cinema Display

Macbook Pro:
Processor: Intel Core i7 2.7 GHz
Operating System: OSX 10.8 Mountain Lion
Hard Drive: Western Digital 500GB 7200 RPM
Graphics: Nvidia Geforce 630M

If my bug about the previous versions is impossible, I'll take your word on that, but the slowdown issue is what is really killing my ability to use Photoshop (at least until I discovered a solution on my own after tech support's suggestions were unhelpful). I've consistently reproduced it across computers.

This is why I made a bug report, because it seems inexplicable to me. I can only hope that someone at Adobe will at least glance at this and research it instead of dismissing it as the user and computer's fault when these three very different setups with the same exact problem should be getting a more keen eye.

Isn't that where my subscriber dollars are going?

I've looked into what might possibly cause what you are describing - and there is no technical explanation for what you describe.

Either you have something in common between your systems that other users do not have, or you have made a mistake somewhere (possibly using different brushes).

If it is just Photoshop CC showing the problem - that might be a possible bug, and we would need more details to narrow down why you are seeing it and others are not.

If there was an overall app slowdown, possibly you just have a corrupt font on your systems (possibly installed around the same time you installed Photoshop CC).

But you have to be leaving out important details, making a mistake in usage, or making a mistake in how you describe the problem.

I to am having this same problem. Just upgraded to cc from cs6 and instantly started having brush lag issues on the same day. The brush is extremely slow to respond to brush strokes and or size adjustments. I have never had this issue with cs6 on this same computer.

On one hand, I'm really sorry someone else has to share in my misery. On the other hand, I'm glad I'm not going insane that this has happened to someone else!

Would you mind sharing your system specs? I'd be curious if there is anything that might link my computers with your computers, as far as what could be causing the problem (barring other solutions, such as resetting your presets, updating drivers, etc. all which I have tried).

Also, does increasing the Spacing like I did improve performance for you?

i am running a windows 7 (64bit) machine with i7 processor with 24gb of ram, geforce 9800 gtx+ video card.
Have not updated anything because everything was running just fine before i upgraded to CC. This issue started happening the first time i tried to use the brush tool in PScc and had continued ever since. I am hoping this might be an issue within PS and hence is why I came here looking for answers. This is slowing me WAY down as I use the brush tool a lot!

I want to let Adobe know this was not happening in PS6. Like I stated I just upgraded to CC a few days ago and instantly started noticing this issue. No other changes were made and no other software was installed. Just upgraded to CC and opened PS and instantly noticed the brush lag.

alright, we need to narrow down where you are seeing problems so we can try to reproduce it.
We haven't seen slowdowns with any brushes - but it is possible that some brush options might have a slowdown, or that there is some other factor (plugins, external apps, drivers, etc.) causing slowdowns.

Does this happen with the default brushes that ship with Photoshop?
Does this happen if you disable GPU drawing and restart Photoshop?
Does this happen if you disable all third party plugins?
Does this happen if you disable all active system utilities (antivirus, backup, font managers, etc.)?

Yes it happens with default brushes
yes it seems to get worse when i turn off the GPU
It also happens in camera raw when using adjustment brushes
Have not disabled plugins or system utilities yet. Will try this next.
When I turned off the GPU I started working on a file then converted it to a smart filter then opened it up in camera raw. the screen would not redraw after zooming in and the adjustment brush was lagging a lot and took so long to respond that i had to cancel it. Then once back in PS i was working then the app crashed. I believe the error was the photoshop app itself that crashed and not a plugin. I am assuming it is from having the GPU turned off as this has not happened in PScc before.

Try turning off font previews for Photoshop and see if that helps performance. Apparently there's one or two fonts that can cause issues when creating previews.

I love trial softwares but that one looks more like a beta version to me. If it doesnt' get fixed before the trial expired, I will have to look for an alternative to Photoshop and from my video, you probably guessed one of the alternatives

I know this post is fairly old but wanted to add to it.  I'm also having a similar issue with brushes (lagging a fair bit in ACR 9-1-1).  The lag is usually a few seconds with the hand tool lagging a minute or so before it 'activates' at which point it's a few seconds and I can only go very very slowly or the move is ignored.  My real issue in ACR though is the magnification in the lower left corner.  When I attempted to go from 50% to 200%, it took 22 minutes before it actually enlarged and the program was completely unresponsive during this time.  I have a widget that shows CPU and RAM usage and the CPU was at about 1-3% for almost all of that time and RAM at about 30%.  It stayed this way till the photo actually enlarged 22 minutes later. This is totally bonkers crazy!  I'm editing a 32bit image, using Win 7 Pro, Asus P8P67 mb, 16 Gb ram, AMD R9 HD7970 video card.  I've tried uninstalling all my Adobe products and reinstalling Photoshop CC but no change.  I upgraded from Photosshop CC 2015 to CC 2017 then upgraded to the latest ACR but that made my 32 bit images totally useless since the latest ACR doesn't support 32 bit images at all so I had to downgrade to ACR 9-1-1.  I should note that this motherboard uses a Marvell Sata III controller which is where the Adata 256 Gb SSD system drive is located and  the other Marvell controller has a new WD Gold 4 TB drive which is where all the photo files are and is also being used as the scratch disc (I have 2 TB available space there).  I have 70% of RAM allocated for Photoshop use (increased from approx 50%) and a 500 Gb WD Black drive on the Intel controller which is totally clear and being used as for the 200 Gb maximum cache allowed in ACR preferences. As a note, the 256 Gb SSD has 111 Gb free space.
