Hello all.
I walked into my studio and found my computer upgrading to windows 10, I didn’t okay it but it was already at 11% when I caught it so I was forced to let it run.  I’m working on a model right now that is only 235465  polys and it’s lagging.  I changed my compact mem setting to 2000 and still it’s lagging.  I was recording using ZBrush’s movie feature but turned it off to see if it would improve performance.  It did not.  Is it because of windows 10? is there a solution? I hope so.
Windows 10 should not cause performance drops. Try using the performance monitor to see what might be using up your resources at the moment.
