As soon as it is shown that NVIDIA is cheating (actively cheating) in a game, I will buy no NVIDIA video cards for a year. Yes, even if NV40 is the be-all-end-all, I will refuse to buy it if they are cheating at Splinter Cell.
I'll buy an nForce 2 (or 3) of course, just because I hate Via even more, and Intel is just too expensive for my tastes.
So yeah. I've said that if NVIDIA is cheating at games, I'll stop supporting them. Anyone else care to join in?
