Hm.. After a few tests, I've found that the fog seems to have been disabled. Anyone can test this by setting the "world detail" level to High. Not highest. A setting of "high" gets rid of the whole scene fog. While "highest" enables the fog to be on the whole scene. But somehow with these new drivers, setting it to "high" or "highest" makes no difference. I'm gonna try to test it with the 45.23's later.
Driver bug or "optimization"... Considering these are beta, I'll give nvidia the benefit of the doubt. But you can rest assured I'll test it again when the Official Det50's are out. On a side note though, how can less fog increase the FPS so much? Everything else pretty much looks nice.
Maybe if someone with both cards can test out which effects are missing and which aren't.
