Mostly, MUCH better framerate (sometimes up to 30 fps with almost all the
detail on) and a nice bilinear filtering which makes the texture maps blend
really well so there is not much pixelization. Sadly, no anti-aliasing
though - which would be nice for Watkins Glen ( the guardrail fences there
just make my eyes hurt ). To me it was worth the $149 bucks for the card.
