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?


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.

    Ok, I 'solved' it. I had group inside group and I ungrouped layers from the top group and it's fine now with and without smoothing.

    It's weird, cause I have document 4500x3500px @ 150ppi with about 50 layers and now with just one group- it should run smoothly.

      Figured it out! Reset your preferences by using the button "Reset Preferences on Quit" from Preferences > General, then restart your system. Worked for me (thank God.)

        I'm having the same issue except it's my Spot Healing Brush that is lagging.

          Try to set smoothing to 0% on normal brush and then back to healing brush

            Same! At least now I know it's not just me. It must be a CC 2018 bug as I also updated yesterday. Also have a project due - super frustrating!!!

              Same thing for me! At first I thought it was my Wacom Cintique 13 pen but it is making me crazy!! It's so slow it's quadrupling my retouching time!!!
