I should clarify. I don't like it when devs leave out optimum support for certain hardware purposely, to favor one of two competing companies. I know nVidia has been doing this for years, and ATi has to respond somehow to stay competitive, but that doesn't mean I have to like it.
I respect companies who refuse the money and try to make their game as enjoyable for both parties greatly. But still, money is what we're all after in the end (well, sex and power really, but I'll save that for a discussion on evolutionary psychology ), so I see the reasoning behind it.
