Hello everyone, I encountered such a problem, went over the new computer, moved from amd to intel, changed only the processor and motherboard, the rest is old (gigabyte 390z ultra. CPU 9900k). After this, zbrush began to work not smoothly, during sculpture it is sometimes felt that the brush does not go smoothly with a delay, and this happens randomly with interruptions. The drivers are the last, the BIOS is also the last.
Maybe you turned on dynamic subdivision by a mistake and it’s why it slows down?
I too am having the same issues - but I purposely use Dynamic Subdiv on low poly mesh (with no real Subdivsions) as always have, and only recently am I experiencing lag and delay on brush strokes.
FPS drawdown occurs for a fraction of seconds during operation
Is it clean install of zbrush? Or OS in general?
Maybe you using sculptris-pro on too dense mesh or very decimated one?
windows new, zbrush. v 4.7. these friezes are at any grid density
ZBruhs 4r7? Maybe try to update.
I tried all versions of zbrush, 4.7 is the most stable
