I don't know why poeple bitch so much for the "W00t" expression. Stupid or not, I like it and I use it as I please...
Moving on, for the ones who think that GTA3 runs smooth on nVidia cards only: You're dead wrong. The game has issues with many kinds of hardware compositions. I've tested the game on various systems equipped with GF4Ti, GF3, GF2, Radeon 7500, 8500 and 9700 with 3 different motherboards (Intel, Via and nVidia based). Mixed results here, including the fact that the game stuttered on GeForces, no matter what type/drivers or tweaks involved (performed a little better using intel platforms, in my tests).
We're not talking about XBOX here, but PSX2! (BTW, Splinter Cell works like a charm on ATi cards).
"Hear me now and believe me later" - Rockstar doesn't want to make the same mistake again and code a piss poor piece of PORT that has issues on a vast majority of hardware.
Anyway, time will tell and the clock is ticking.
