There is something about WinQuake that is so pure. Of course DOS mode on a fast socket 7 system is the most pure, but WinQuake retains the original visceral feeling to the combat and the insane pace. GLQuake (especially the early incarnations), while jaw dropping back in the VooDoo days, was just too plastic. Of course we overlooked that, because we had bilinear filtered Wizards Manse, running silky smooth in 640x480. But you have to admit the Flashblend and Polyblend effects looked very fake. Quake running under original GL is just too plastic...
WinQuake is pretty much as good as it gets. Having spent probably close to 5000 hours playing Quake in one form or another, whenever I play Quake for a quick run through even today (which is around every month) I always play in WinQuake at 512x384. Even with all the goodies of Darkplaces engine, Tenebrae, DirectQ... nothing can touch WinQuake for pure adrenaline.
I did install Quake on the K6-3 550 machine I built last week and had a quick blast. The PS2 ball mouse, 19" CRT and (dare I admit it?) ... INCONSISTENT framerate brought back a feeling inside I havent had since 1997 and my Pentium 200 vanilla. I was 16 all over again.
Timerefreshing the start position on that system gave 43fps if I recall. And the timedemos ranged from 52-68fps. All of those were in 320x240. Pure bliss...
