Heheh, Scuba, Voodoo 3D Rush acceleration is CRAZY old. We're
talking the actual Voodoo series graphics chipset, which has been
long-gone for years now.
Color depth should be easy to fix
by adjusting your monitor settings in the regular properties window. As
for the graphics acceleration, any graphics card will do, you can
probably find a cheap PCI card to plug into your machine.
As for RTCW:ET, it really is amazing, I've been playing for a couple years now.
Oh yeah...RUUUUN! IT'S GOJIRA!!
