    Major brush lag even with low (~30%) smoothing

    Sling_Shot13 Level 1

      Photoshop CC 2018, fully updated (upgraded to 2018 and downloaded recent update from early April/late March)

      OS X, fully updated

      iMac Retina 5K

      16 GB Memory

      Allowing PS to use 9998 MB memory (recommended: 7851-10278 MB)



      I hope someone can help me. My brushes have very noticeable lag even on low smoothing (around 30%). I'm using the basic PS brushes, and Kyle T Weber downloaded packs. I work in 300 dpi resolution and the lag is present when the brushes are small (8 px) and also when large (100+ px) but only when smoothing is on. Zooming in or out doesn't seem to make a difference. The lag appears around 25% smoothing and gets almost unusable around 45% smoothing.


      Is this normal?


      I'm using a fully updated Wacom Bamboo drawing tablet (it has the latest drivers, which are old, but I get the same problem with my mouse, so I don't think it's my tablet)


      I have already tried the "reset preferences on quit" fix as recommended elsewhere on Adobe forums.


      Please let me know if you have any suggestions, or need more information.


      Thank you!
