So I have a 640MB card here that drops to like 10 fps when I have a big explosion in C&C: Yuri's Revenge. I thought this was like a great card that would let me avoid these hiccups. It reminds me of my 9800XT. Is there something I can do to optimize my 8800GTS's abilities? Maybe in the NVidia control panel or the BIOS. NO OVERCLOCKING!
