I am using ZBrush 4 in Mac OS X Lion with a Wacom Intuos4 Medium tablet. When I move the cursor/brush with the mouse or trackpad it moves fine, very smoothly. When I move it using the tablet (no matter whether its the pen or the mouse) it moves ‘jumping’ around, like low frame rate on the brush only, it doesn’t move smoothly as it should. It makes sculpting uncomfortable etc. Anyone having this kind of issue?
The problem can’t be in the tablet itself, since it works fine everywhere else…

You’re in the wrong group friend. Try posting over in the ‘Questions and Troubleshooting’ forum.
Admin’ will probably move your post there shortly.
Having exactly the same problem… my solution…
I’m running windows for now…
Sorry for posting in the wrong forum, couldn’t find this one at first.
I won’t use Windows anyhow. THis has to be solved. I am sure there are a lot of mac users around. I guess they don’t have this problem somehow…
Oh trust i NEED to find a solution as well, it’s just a temporary solution to my problem…
Someone must have, we can’t be the only ones…
Updated to 10.7.1
Seems to have fixed the problem 
May have spoken too soon… still doesn’t work…
Until this issue has been resolved you may find turning off Preferences>Performance>MultiDraw helps.
Wow dude that solved the problem! Thanks! That multi draw option doesn’t seem to really affect performance (at least for low res meshes) then its not a problem to turn it off…
Thank you!
