In WOI I had an absolutely astounding performance increase on my old Nvidia 7300 Go. So much so I had the rude realization that my former prowess in the ether was owing to my having played the game at under 10FPS. Then my Toshiba died.
My new rig, a Dell Studio comes with a 512MB ATI Radeon 4570. Quite naturally I had my expectations. ATI delivered without a whimper- I only had to revert to stock ini configurations for some terrain mods. Also my graphics settings are not application controlled so go into the ATI Catalyst Control Center and play around.
In WOI I experience 30-58 FPS. In WOV, it more like 8-58, owing to the cursed AAA. Not only does your s**t get baked while scooting over Hanoi but it happens in slow motion!
