I can play sc2 on ultra. skyrim on max. I played d3 beta on max just fine but now it lags horrible and the only thing i changed was from 32 bit to 64 bit windows. I have a new grahpics card but i even tried my old one i used in beta and it is 10 times worse than new one.
windows 7 64bit
i5 quad core 2.66
I really hope there is a fix eventually. The game should not be jumping for me.
