I did just port fitzquake to dos, lol. I'll test out the performance differences. haha wow, that actually gives me a bit more optimism about Q3A / OA on DOS. :) https://bitbucket.org/maraakate/fitzquake-dos Done very half-assed in under an hour, but it is enough to play it. You'll probably need a …

Also, I never knew how terrible the rush cards really were, take a look at this old review: http://vintage3d.org/3dfx2.php Whatever it was tested on it was slower than a voodoo 1 with Quake 2 and likewise got ~15fps in timedemo demo1! It doesn't mention the CPU setup or anything else, but I'd …

... CVS setup and grabbed the final development branch of glide3x that was worked on. ... Testing resulted in an approximately 2fps boost in timedemo demo1.dm2 in quake 1 at 640x480 on the P3/V3 combo. Not worth upgrading only for that 1 or 2 fps gain, considering the possibility of something else …

Mesa3d has a site to browse their commits: http://cgit.freedesktop.org/mesa/mesa/. Under branches, I was looking at these: mesa_5_0_branch; mesa_6_0_branch; mesa_20040127_branch. And these particular commits looked interesting to try, even though probably not worthwhile unless they bring an obvious …

Of even more interest to you might be that I finally got CVS setup and grabbed the final development branch of glide3x that was worked on. The last commit was in 2008. There are two things to fix and they are in minihw.c. fenceVar has to be changed to be non-static or the DXE resovler will complain …

And yes, it's true the minigl was basically for the quake 1/2 family of games.

I have already done extensive testing on running swapinterval and swap_pending and here's the deal... Leave swap_pending at it's default value, 3. This is just like the maximum number of frames to read ahead or whatever it's called in nvidia. Unless you're having odd input lag issues don't fool with …

And to verify otherwise. with MTRRLFBE.EXE on my Pentium 3 in DOS @ 640x480 on timedemo demo1 I get 112.8fps. In windows it's 119.4fps. So the speeds are relatively close if your chipset allows this to be set. EDIT: Forgot to mention that was Quake 1, sorry!

And for the record... even in windows I only get about 30fps in timedemo of demo1 with a voodoo 2. So it's basically unplayable at that point unless you tweak cvars to severely reduce texture size and everything else, basically making it look like a smeary piece of shit which defeats the whole …

I also noticed the card really needs LFB write combing with MTRR's set to get comparable windows speeds and Pentium 1 does not support this but maybe windows has some trick in their drivers to set it up on such a computer.

Probably because of the library overhead. My P1 200 can barely do it on a voodoo 2. A pentium 2 with a voodoo 3 or anything faster will be much better.

What did you get at 320x240 in Windows? I guess we should add a note about using this utility or expect poor performance.

but yes, put MTRRLFBE.EXE in the same directory as quake 2 because it needs CWSDPMI.EXE to load.

That's interesting the minigl driver should be much faster.

Are you running this inside windows 9x dos box?! But yes, 3dfx minigl will always be faster, try comapring to regular opengl if your driver allows it (voodoo 1 and 2 won't)

Is regular Quake2 using the 3dfx minigl driver or the default opengl?

Also, I forgot. Is gl_ext_multitexture and gl_ext_pointparameters set to 0? If they were enabled and you disable them you will need a vid_restart or restart quake 2. Another thing to try is gl_ztrick 1. And finally, if you're getting a little desperate you can disable the dlights entirely with gl_ …

Wow. That's pretty slow. Have you tried using http://rayer.g6.cz/programm/mtrrlfbe.exe ? just do MTRRLFBE.EXE LFB WC. Should increase your speeds if your chipset supports it.

Also what is the cpu? I noticed all this 3dfx stuff seems to be dependant on the CPU.

If software z-buffering is used it must be something in the rush driver as we are using the actual ref_gl from id software with some special performance enhancements by knightmare.
