16xQ AA Super Sampling

5 - 15 FPS



Supersampling vs. Multisampling is the deal breaker. Super sampling looks better (marginally) but takes a HUGE hit on FPS. Personally I perfer to play with AA off and get smooth 60 FPS, dont really notice the jaggies much.

P.S. This is running XP with the cvar mods to get very high on Dx 9 (looks nearly identical to Dx10 but you get better performance because you dont have the Vista hog eating your resources)
