er, this is an Amiga forum and they want to play Quake on their machines, so let 'em. You're argument reminds me of a friend of mine who used to play Battle of Britain on his 286 and then found it unplayable on a pentium years later (too fast to play). For quake, 20fps is playable in 320x200. And I doubt John Carmack was playing it in 1600x1200 & 85fps back in the day it was released. Why don't you go tell him he's not an 'inteligent' quakeplayer (whatever that is).
Anyway, GLQuake and Blitzquake both work fine, at least they did on the CSPPC/CVPPC setup in my A3000 and on a Prometheus/Voodoo3/GVP4060 in my A4000. You need to use iirc at least version 4.2 of Warp3d. Make sure the gears Warp3d demo program works for ppc and 68060. There is a readme file with Blitzquake which explains pretty much all of it. Just keep trying, and make sure you set the stack to the required amount if so needed (maybe blitzquake requires this, I don't remember).
