You know, I loved nVIDIA back when I had a GeForce 2 Pro and the drivers WORKED. Anyway, I'm not sure if it is my drivers for my GeForce FX 5600, my sound card drivers, or anything else regarding my motherboard.

Everytime I try to play Serious Sam, it locks up. And on top of that, it moves REALLY slowly as it plays before it locks up. Now for a GeForce FX, that's crap...and it happens in any mode, Direct3D or OpenGL.

I have the latest drivers for eveything else (I got the VIA Hyperion 4-in-1 drivers, latest Audigy 2 drivers, etc.)

This also occurs on my sister's computer which has a GeForce 4 Ti 4600. I did the same to it regarding the drivers (VIA Hyperion 4-in-1 drivers, etc).

I also have WinXP Pro w/Service Pack 1 and Direct X 9.0 on both systems.

So since it's most probably the Detonator drivers, which version should I go back to? If it's not the video cards, then what could it be?
