Guys just came across this on the Inside Sim Racing site, Nivida have release some settings to enhance the game for your Nivida Cards, thought i'd share it.
32xcsaa is about the same fps as 8sxAA with an gtx460.
I did some testen and there isn't much difference, the only the is that 4x supersampling makes the image a bit darker.
I always use 8s with invidia inspector on every gmoter game and it looks very good.
