I still hate my ATI card, but although AMD made it as hard as possible to find updated drivers I have - and that updated drivers for about half my computer at the same time!

 

Poser Pro 2012 has been mostly stable since... annoying slow at too many things, but MUCH more stable :)

 

My Nvidia based machines tend to get their video card drivers updated more regularly, even if I just wait for Windows Update to point out there's been an update! (not had that happen with the ATI card yet).

 

Cheers!
