Okay, this I can't explain.
Whenever I play Call of Duty 4 for a prolonged session, say 2 or 3 hours, if I quit and immediately load up Crysis my frame rate is almost doubled. Somewhere between 30 and 40 fps. Normally I get in the mid 20's. I doubled checked the settings menu, it didn't change between loads. Some screens:
Does COD4 overclock my GPU? Switch on some hidden feature? I have no idea. But as soon as I quit Crysis and load it back up, or restart my PC, my frame rate drops back to the mid 20's.
Can anyone else check this out?
My specs are:
Windows XP (haven't tried this in Vista)
