Good timing on this topic. I have just finished a new build i7 920, GTX260 w sli, Win Vista 32, 3 g memory.
I used the settings above in game and in the NVIDA control panel. Getting pretty good results. High frame rates and no real swizzles.
I am, however getting some banding in the sky low above the horizon where it graduates into the broader sky, some odd textures on the plane (look like dark grey patches), and runway does not seem like it is textured right. Almost like the bit depth is not right.
Tried to post some screenshots but not sure how to do this.
