I downloaded the demo, and tried to fire it up only to have it freeze up a second or so after loading. Black screen, Windows "ping" when I click the mouse button. Had to end task after the 3-fingered salute.
I tried changing video modes and resolutions to no avail.
My system is:
PIII-450 (Intel)
128 MB RAM
Voodoo3 2000 16MB
Soundblaster 16
Any ideas?
