Win 7 64 bit vs XP 32 bit 2D results

[brad1138]

I just upgraded from XP 32 bit to Win 7 64 bit. Every test score went up, except 2D, which plummeted from about 1100 to 250. I ran the test a few times and I had the latest drivers from Nvidia's web page. What would cause that?

Also, even thought the 3D score went up (I think that was more to do with the addition of the DX 10 test) the frame rates were 10-20% lower in every test.

Thank you,
Brad
