I have been using Vista 32 bit since the launch and have been happy with it until lately when most of the games i am playing are running on a very slow FPS for my type of system I am running.
specs:
athlon 64 3800+
3.5 GB ram
120 HDD space
EVGA 8800GTS 320mb
when playing games such as Team Fortress 2 beta, half life 2, and half life 2 lost coast, and FEAR i get a constant FPS rating around 35 fps when my other desktop running XP with a weaker 8500 GT and an Athlon 64 3000+, runs them around 100 FPS.
I have heard that when Vista runs these games in compatibility mode for DX9 that it slows them down because its an emulation. I know that may sound like speculation but it may atleast be an answer? could anyone maybe shed some light on why these games perform so horribly?
