ATI and HL2 team has screwed nvidia.

Yes, and Carmack and Nvidia did precisely the same thing with the early
Doom3 benchmarks. Remember those, when it was shown 'conclusively' that the
5800 beat the 9800 hands down? Even Carmack got suspicious of all the
Nvidia tweaking surrounding those carefully controlled benchmarking
sessions. 'Ultrashadow' my ass!

What goes around comes around, Nvidia's bad karma has caught up with
them.
