I had vista 32 bit installed for a week or so and everything worked perfectly. I could play crysis on highest settings and highest AA with barely any lag, and on high with absolutely none. Now I have XP 32 bit and can't play on medium with no AA, it's way too laggy. I checked my card configuration and it says 650 core clock and 950 memory clock. Does this sound right? I checked the manufacturers (eVGA) and it says the memory clock should be at 1800. What is going on here?
