nah.. I have a 2 ghz celeron in this computer with a geforce2 mx400 card (64mb) and 1 gig of ram.
Even on the lowest quality settings at 640x480 it's all herky jerky.
Just upgraded the drivers, but not expecting much, if any, improvement.
Maybe theres a third party opengl driver or something.
Wolfenstein runs great on my setup though
