Logically, the quality/capability/status of your 2d card should be completely =irrelevant= when running fullscreen 3d. It should only matter if you run your 3d in a window at a higher resolution that what the 3d card can handle. In a perfect world this would be true... But because of LAME OS/video drivers/hardware reasons, the 3d card's bit depth is slaved to the 2d card's. So... 4 megs on your 2d will give you 1024 at 32-bit depth. And your 2d card's refresh should keep up with your 3d at high bit depths (pretty easy nowadays at 640 mind you). The greater the bit depth on your 3d, the better the visual quality, as each filter leaves small geometric patterns that multiply with each pass. As Quake3 is likely to use more passes, this will become more noticable. >The Voodoo chips sets (1 or 2) don't support 24-bit color depth, do they? Setting 2d depth to 32 gives these readouts on the console when I startup Q2 with voodoo 1: Initializing OpenGL display ...setting mode 3: 640 480 FS ...attempting fullscreen ...using desktop display depth of 32 ...calling CDS: ok GL PFD: color(16-bits) Z(16-bit)
