Sadness. Maybe I won't be able to utilize 3.3. I tried to SubSurf my apple stem and Blender crashed. For kicks I tried SubSurfing the default cube... same issue. I can put just about any other modifier on the cube with no issue whatsoever, but try SubSurf and bye bye Blender.
Anybody else have this issue. I would really like to stay with 3.3 if at all possible.
My apologies for posting stuff that I could have researched prior. Per google, I was able to ascertain that going to Preferences>Viewport>Subdivision and uncheck GPU SubDivision, voila problem solved. Maybe it's because I haven't got a GPU?? Maybe this will help somebody else having the issues I guess.
