Photoshop CC 2018 Brush lag

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?

    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 too am having an issue with a slow Healing Brush tool. It happened as soon as I updated from CC 2017 to CC 2018. My settings are optimized for GPU acceleration and RAM, and I have 2 SSD scratch disks, but I'm still having this lag. Again, it was fine in CC 2017, an hour later when I updated to CC 2018, it was not working correctly.

    System Specs:

    Windows 10 Enterprise

    64GB DDR3 RAM

    NVidia GTX 1080 GPU

    Intel Core i7 Broadwell

    Dedicated 250GB SSD Scratch Disc (sATA)

    Dedicated 500GB SSD Scratch Disc (sATA)

    I do skin retouching. I can't have a 5 second lag each healing stroke. It's ridiculous!

          How can Adobe not have responded to this!? Such an annoying bug.

          People rely on this software and trust it to work. It is used for business and needs to function properly so that deadlines can be met.

          I update reluctantly every time and for good reason.

          Adobe, please respond with a fix ASAP!

            It's more than annoying, it's a work stoppage issue. I simply can't use 2018. It's too slow to even consider right now. The new brush tools have destroyed PS. I have 2017 and 2018 installed side by side, just waiting for a fix.

              Here's something to try, as suggested by another Forum user:

              "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. I don't know why this worked, but it did."

              Please let me know if this helps. Thanks.

                  CC 2018 is near unusable at the moment. I am using the Mixer Brush to clone paint from a photo and after a few brushstrokes terrible lag occurs; I make a brushstroke and then the cursor becomes the circular flashing dots showing that the laptop is catching up.  It seems that when I first start I get a short period of normal fluent brushstrokes, but then the terrible lags begin.  Has anyone found a solution to this yet?  Why might the brushstrokes be ok at the very start of a session and then start delaying? The problem arises whether I am zoomed in or out.

                  I'm using W10 Pro on a Dell XPS 15 9550 laptop and a Wacom Intuos Pro with Grip Pen.

                  Thanks

                      I was having this issue and did the recommended actions of setting smoothing to "0" and going to "Photoshop CC> Preferences> Cursors and uncheck 'Show Brush Leash While Smoothing' box" and that corrected the red line (SO annoying). I am also finding that, since the update, the 'skin smoothing' actions on my plugin is not working correctly. Is anyone else having that issue or know why that would happen? It involves painting on a mask with a white brush? Plus those stupid 'help' pop-up images are coming up constantly. Now I will have to see if I can turn them off.

                        Same problem but with less severe lag -- the pixels that the brush is putting down are noticeably behind the cursor position. Tried prefs rename, doesn't fix it. And yes, customising prefs takes ages and is not a proper fix to a performance problem. What does work, is using an ancient version of photoshop

                          This is an Adobe UX fail and caused a whole lot of non-productive hours. The problem is the Brush Smoothing setting. If its set anything above '0' it activates a whole bunch of setting options that are not needed. If its set at '0', the issues go away.

                          I had the same issue using a combination of Healing Brush and Brush. It also affected my Wacom Tablet as well as the Mouse. Try this to get rid of the lag in the Brush:

                               Select your Brush Tool

                               Go up to Smoothing and set it to '0'

                               This deactivates the options found in the Smoothing Panel—That Gear Dropdown Icon next to Smoothing

                          If you need to set Smoothing above '0', the Smoothing Options in the Gear Dropdown activate a group of options such as Lag and Pulled String options again, which are a pain. You just need to figure out what is relevant to you. That Pulled String effect may also be switched off in the:

                                PhotoShop Preferences > Cursors > Show Brush Leash While Smoothing

                          I assume this applies to PC versions as well.

                          Hope that helps

                          This sounds like the healing stamp/brush issue. It's the same symptoms.

                            Hi there.  I had the same problem in Lightroom Classic and PS.  Seems there are different solutions for different people, but will share in case it helps.  Adobe Lightroom GPU Troubleshooting and FAQ

                            My problem was multiple graphic cards.  One is Intel, and the other Nvidia.  I used Solution #3, section 6, and modified all my Adobe programs from the Global/Auto Select option to Nvidia solely option.  This did the trick for me!!! All of my products are now lightning quick.

                            I would recommend updating all your drivers PRIOR to changing.

                            I do hope this helps!!

                              As soon as I open photoshop 2018 everything slows down in the computer. Illustrator fine, XD fine, but as soons as I open it everything slows. Like doing WINDOWS + D to go to desktop lags so much, so much that the icons in the desktop disappear.
