The title is vague because I'll probably have more to say about Blender soon, and others are of course welcome to bring their own Blender related stuff here as well.
Does anyone happen to know what might cause performance issues or stuttering while sculpting? I get this even at around 70k polygons, so there must be something wrong. Anyone else using a Radeon 6850 and Blender? I found some tips but nothing to address this situation.
