I installed this, and also installed StormMesa and copied the agl.library over the stormmesa one as directed. However, I can't get most of the demos to work (the OGL logo, the ideas demo and the sky one with the paper aeroplanes work, but atlantis, underwater don't).
Most upsetting is that GLQuake doesn't seem to run :-? . The screen is just completely white. If I press ~ to bring down the console, I don't see it, but can type timedemo1 demo1 and hear it going, plus I can see a black & white untextured gun and the untextured zombies, but no walls or anything else
I've just downloaded the Payback demo to see if that works
