General Conclusions

Adding AF is a significant performance hit for the non-G80-based products, which isn't surprising given the nature of the game. In contrast, adding AA is an easier ask for all the hardware configurations in GTR2. The eye-catching performance comparison is between 8800 GTS and 7900 GTX, with the older single-chip product beating the newer one, and 7950 GX2 almost getting one over on 8800 GTX. Some driver work to be done, perhaps?
