Right now I've been trying to play Half Life 2, Team Fortress 2, Call of Juarez and STALKER SoC. All these games I should be able to play at high if not highest settings yet all of them have extremely low fps. The stutter is horrible games freeze often and I can't do anything for most of the time. My specs: Athlon 64 3.2ghz 32000+ Nvidia GeForce 8800GT 256mb 1gb RAM Latest drivers, directx, recent defrag. I could run these games at highest on windows XP and I'm considering downgrading even if it costs me a hdd format. Is there another possible solution. I did try disabling aero interface too which didn't do much. Also ran them with and without compatibility modes.
