I don't understand how some people is defending this.

Some of you are saying that NVIDIA paying to improve the performance of some games in their hardware is fair, is business. I agree. This is not what is happening.

Purposedly damaging in the software the performance or features of that software on hardware of competitors is not fair, and it's not something that can benefit in any way to the consumers. That is: us.

I don't understand that anybody that is not a NVIDIA employee, has not a huge investment in NVIDIA shares, or has some kind of romantic relation with a NVIDIA employee, can accept that and even less defend it.

This is not the first place where I read about Batman:AA and its purposedly AA disabling when an ATi card is installed on the system.

This thing is an absolutely embarrasing thing for both NVIDIA and the developers of the game. I don't know about the other games that are named here (I doubt an ATi representant is exactly unbiased), but made in one title, who knows about others...

That thing is little short to include a wait function of 10ms each iteration of the game loop if a competitor product is detected to damage it's performance.

I'm not by any means an ATi defender, or an NVIDIA hater, but as a consumer, things like this turn my stomach.
