another method is play d3 games in windows mode and resize it to small. it working fine to me.
just start new nightmare :)

i did this stuff and d4 still is grey screen answers any1?

the links I posted can't answer your questions? Strange, strait from Blizz themselves

Start d2 in windowed mode, update your graphics card, and restart computer

Depends which graphics card you updating, D3 only works with certain graphics cards or updated ones. ie: windows vista, G-Force 6150 slow and choppy, yet my laptop with a raedion ( how ever you spell it ) will handle better.

Go search through the blizz/bnet forums for D3 and graphics, your sure to find the info you need
