Hi,

I updated PS yesterday and everytjing was fine, but today suddenly I got big brush lags. With smoothing on or off, no difference.

Lag gets even worse while zooming above 50%.

I've restarted preferences and PC and nothing happens.

I'm losing half a day trying to figure it out and its really nervous situation. Any ideas how to fix it?

Windows 7, 16 GB RAM, GTX 970, Intel i5 4570

SOLVED THE PROBLEM

It looks like Adobe, if I'm not mistaken, added a new option in the 2019 version and by default, it's on. What worked for me is turning off "Enable Preserve Details 2.0 Upscale" under the Technology Preview preference. Let me know if this works for you guys.

I just worked on a issue with this problem. I turned off the "Open Cl" in advance graphics settings and restarted PS and it worked. Can anyone confirm this as a potential fix for brush lag?

Most of the time, switching off all advanced graphics all together works. I've only had this issue on older machines with newer versions of CC.

I wish I had stuck with my old Wacom drivers, Windows 7 and CS6. Those were a good few years of no issues or workarounds.

Go to Preferences > Performance > Graphics Processor Settings > Advanced Settings > Set Drawing Mode: Basic

This allows you to us minimal resources from your graphics card and should still allow you to use the rotate canvas, which is something I can't live with out, while getting rid of that annoying brush lag.

Also, remember to restart photoshop to make these settings take affect.

I hope this helped

Even in CC 2017 that doesn't works neither.

I'm leaving this here as an extra info for the staff. My problem was a really annoying a few second delay on brush strokes and if I wouldn't move the brush at all it would not leave anything on the paper even with build up turned on. Disabling smoothing fixed it for me and at least with a very short test it seems to run like a dream. This problem started only recently, after re-installing my entire pc - I had the PS CC 2018 running even in the last one too with smoothing on 10% with no problems.

I have Cintiq 27QHD + an Asus monitor + PS CC 2018 with all the current updates.

Hi Anna. No Adobe staff here. You can leave comments on the Feedback site, if you want to get information to the development team. Jeff Tranberry and others follow that site.

If you search that site for 'brush lag 2018' you'll find a few hits.

FWIIW, I am using three large screens, Windows 10, and an Intuos4, and I never have any lag issues. I work with rulers turned on.

My system is a six year old 3930K with 32Gb memory. Until two days ago it had a GTX970, but I had to remove that because it is going in a new 7900X build, so I am now using a GTX570. While things like Select & Mask are not working well with the old GPU, I have absolutely no difference regards brush lag.

The test we use is to create a 30,000 x 30,000 pixel document, and run a 5000 pixel fully hard brush with spacing set to 1% from corner to corner. This takes 31 seconds with the GTX970, and is two seconds slower with the GTX570.

I have the same problem,nothing seems to work. I contacted adobe online support twice, they´ve checked everything that was possible to check and still doesn´t work. Smooth on or off, it´s the same. I downgraded it to 2017 version (the last version it worked fine) and to my surprise, I had the same issue . So what now? I need it to be fixed, I have clients that are waiting, I lost two days of work trying to fix this and not even Adobe support can give me a solution.

Around 2015 I contacted adobe for an issue I was having with Ps. It was different from this but the solution was right and I think that the solution here it might be the same: first they asked me to delete some adobe log from one of the system folders (can´t remember now) then, they asked me to install the previous version and It worked. So...? I can´t think of any other solution. I did everything that was in this forum and the only idea is to go backto 2017 version and make it work by intaling Adobe CC 2017 or doing something like I did in 2015.

Try this (from another thread about poor PS performance): "Delete the AAMUpdater folder and the OOBE folder in the C:\Users\[your user name\AppData\Local\Adobe folder. You may not be able to completely delete the AAMUpdater folder, as AAM is running. I then did a reinstall of the AAM, actually, since it was installed, and I just deleted part of it, It gave me an option to repair it, which I did."

What I did, I turned of the smoothing found in "brush setting" then "brush tip shape" then set the spacing to 7%. It worked for me.

I was having the same problem with the Paintbrush and Healing tool. I solved the problem by setting SMOOTHING to 0%.

Nope, Solomon, I tried all that and I'm running Photoshop on a strong machine built for graphics. I ended up exporting what I had done and finishing it using Krita - and had literally zero problems. Ticks me off because I've been using Photoshop for 16 years.

Sorry to hear that Jacoby.

I am using an iMac (Retina 5K, 27-inch, Late 2015) / 4 GHz Intel Core i7 / 48 GB 1867 MHz DDR3 with Photoshop CC 19.0 Release

I was having lots of problem with the super slow lagging. I called Adobe and the tech told me to turn off the Smoothing to 0%. It's been 5 days and it's working fine. No more lagging. I am keeping my fingers crossed that this solved the problem.

Also having this issue. Lag is pretty small but incredibly annoying. Turning off smoothing doesn't help, updating Wacom drives doesn't help, restarting PC helps but only for a while. 2 months into the issue, nothing happens. Also switching back to 2017 version doesn't solve it, though it worked normally before the update.

Come on, Adobe! This brush lag is ridiculous! I have 8GB of memory and a 1tb dedicated scratch disk, and even so, what should take me 20 minutes to paint is taking upwards of an hour because of this insanely frustrating lag! What the heck are we all paying you $80+ a month for? FIX THIS, PLEASE. You're costing some of us A LOT OF MONEY.

I'm having the exact same problem. damn.
clearly it's a bug right? Hope photoshop can fix this soon!

I believe it's now solved. In CC2018 the default setting of brush tool might have been setr to 'smoothing' which is a badly implementen new feature to make the brush follow a smooth path.

Untick the box of 'Smoothing' in the 'Brush settings' window as shown below:

Good luck!

Ok, I've tested the above method and can attest that it does solve the issue. However the lag is still present after heavy work. It creeped back after about a half an hour or so.

A permanent fix that I have found was to switch to single monitor mode when working with CC 2018 along with the above brush smoothing fix, but in doing so I lose three screens and thus I have to alt tab my way around my workflow which hinders a lot of my retouch process . I do hope Adobe finds the issue and issues a fix so I can use multiple screens again.

Hello everyone,

I have recently made the update too on Photoshop CC 2018. Two pcs got the update

PC1:

Ryzen 1600x

8Gb RAM

GTX 1060 3Go

Single monitor setup

windows 10 pro version 1709 build 16299.125

PC2:

Ryzen 1700x

16gb RAM

GTX 1080

tripple monitor setup

windows 10 pro version 1709 build 16299.125

PC1 works flawlessy with no problems whatsoever, no lag with brushes etc.

PC2 always launches Photoshop on my third monitor and not my primary monitor for reasons I do not know why. One in every other startups it would not detect my GTX 1080 card, although ACR finds the card no problem. Brush problems are present, even zooming in and out sometimes crawls to a halt.

My guess is that Photoshop CC 2018 is having problems with multiple monitor setups, I'll try launching it with only one monitor active again tonight to confirm, but for now it's very frustrating to deal with this bug. Previous version of CC never had this problem and I have been doing 3 screens since July no probs.
