It sucks for gaming...
I was a Vista User but now back with XP
I switched over to Vista after seeing the difference in graphics(DX10) in Crysis and other Dx10 games,the difference was very significant,visuals were far better(only if you have a good Hardware).
But anyways let me comeback to the matter at hand,I also changed the compatibility mode to xp,I have disabled UAC and also every process is run as admin,so no problem with that.
Can somebody please guide me what else should i do after extracting the UT source.
