If you are talking about the 23.11, I have one problem in Janes WW2 Fighters, it drags and is choppy with 4X FSAA enabled. This is the only game that is adversely affected, I got around it by just playing at 1600 x 1200 x 32 without FSAA. Go to Add/Remove programs and remove all Nvidia drivers. Restart and set to Standard Dispay Adapter (VGA). Click the start button and then click on find. Remove all NV*.* in drive C: Reinstall which ever driver you want. While not the fastest and no fastwrites support, the 8.03 looks very good and is extremely compatible with just about everything.
