Datumplane:: Starsiege has posted a Q&A with Dynamix' Mark Frohnmayer, who confirms that the GeForce's transform and lighting features (T&L) will be supported in TRIBES 2. Here's what he had to say:

Yes, T&L will be supported in Tribes 2 (we're using OpenGL's transform pipeline, so it'll just work) Since we don't have a sample board, I can't comment on performance, but I expect it will be very good. Tribes 2 with the details cranked WAY down should play on pretty much any card with a good OpenGL driver... that said, expect play on low end cards to be suboptimal.
