Since I've built this system it has run real smooth, with one exception - video performance, especially with DirectX. Animations are beautifully rendered but real choppy and even gameplay is affected in certain games. It was a fresh install of Win98 SE and I have tried all of the various drivers out there - Detonator 2.08 to 3.76 Beta; all the Creative Labs versions; CL Unified driver. Nothin has improved the performance. The system is an Athlon 650, Gigabyte 7IX with latest BIOS, 160MB PC100 RAM, Creative Labs TNT2 Card. Any ideas or suggestions?
