Hmmm, looks like i have to try to disable Aero too, when playing. Since 9.3 i got really bad fps, however was able to increase them dramaticly by overclocking my pc. Previous: C2D E8400 @ 3.0 ans 1333MhZ FSB now on 3.6 with 1600MhZ FSB. Looks like the new lightning uses extremly the cpu, not the GPU. When you talk about 88 to over 100 fps, what are your settings? Do you set the objects higher than "default"? I have currently "too many" objects with "high" distance and @ 25fps. The GTX260 is not the best, but benchmarks say its way better than a 8800 which i still very common.
