i have just reinstalled vista on my system now i have a stable overclock on my E6300 and 2GB RAM, when i go to play STALKER it is completelly unplayable. i cant see anything but the sky. i was told the new drivers fixed the problems people were having but they have made it worse for me. the game works fine in XP so i know the hardware isnt causing the problem.
any help on fixing this would be appreciated
