Serious Sam 2
Serious Sam 2 now, the Sierra De Chiappas demo to be specific. Serious Sam 2 is not quite DirectX 8 class in terms of how it uses a card, with no shader programs to speak of, but it's multitexture heavy and responds very nicely to anisotropic filtering, making it a nice benchmark for us to use.
A quite linear performance drop off from the ATI, with either the NVIDIA driver doing something right in the initial IQ test, or the driver fails to apply aniso or antialiasing. Looking at the IQ with the 45.23 drivers, it appears to be rendered correctly, but my eyes may deceive. We are obviously system limited in the first case, with equal performance from both.
Benchmarking further down the road with the new Detonator 50 drivers will be interesting.
