Here's how Q3 looks on my system during play.
I can get "decent" framerates at 640x480 @ 16-bit-color with texture quality on the 2nd notch.

I 'can' do 32-bit, but then we're talking seconds-per-frame instead of frames-per-second. )






These are higher resolutions &/or more detailed textures.
Completely unplayable on my Stealth II, but they look nice.







And here's proof that my Stealth II is unbelievibly fast...
