AMD is, I think, releasing press releases just for giggles. This one is pretty insubstantial, but it linked the neat demo video above so it’s worth mentioning. Essentially, AMD is attempting to extend its current (and possibly short-lived) dominance by emphasizing how well the conquering 4800 series works with DirectX 10.1. I have to say, the lighting tools shown in the extremely long ping pong ball demo above are pretty nice — the occlusion is subtle and the global lighting is effective. I dare say my next video card purchase will be a Radeon.
