My system
Phenom 9600 vanilla
MSI K9A2 Platinum BIOS Version 1.4
Corsair Dominator 4GB 2x2gb DDR2 PC28500 C5
Visiontek 3870 512MB in cf
PSU Antec True Power Quattro 1000watt
Vista Home Premium 64-bit
Everything is running great no crashes, but my game performance is crap compared to XP Pro 32-bit. With vsync is off in XP i get a 60% load on both GPUS in Team fortress 2. It droped to like 10% in vista. In game play fps went from 40- 80 fps in XP to Vista 30-5 fps. Is it a driver problem? When CF is disabled same problem, but with a 30% load on the gpu with worst fps. HELP!!!
