wow, that's the most bogus PR I've seen in a long time.. I must admit I don't know the level of the ATI driver tested, but the nvidia driver tested is a very old and known to be poor early nvidia driver that has been superseded significantly. and they're not even testing on the same vista builds!

Yet the latest ATI Vista driver doesn't work for my x850XT video card on RC1. I know it's early and I'm patient but reading this in that light makes me shake my head at their boasting.
