Yesterday I installed Win 7-RC 64bit on a new Intel 160 gig SSD. The install was easy and fast. However, COD-WaW runs poorly, lock-ups, etc. I used the nVidia 190.62's 64bit ver. I'm back to my original Raptor HD with Win XP 32bit, and the game runs like butter. Different drivers would prob be better? Thanks for any help.
