Oh. I did note that there are recipes just 20 lines long to activate mtrr, or at least that I recall. There are longer samples which robustly check whether the registers are available and then turn on one of the sets. I looked at it out of curiosity between maps of rubicon pack. I may try pack #2 today -- thanks!

I am sorry to bump that old thread, but:

i have serious FPS drops on fitzquake , qdos, q2dos, uhexen2 dos.

comparing to original glquake its degradation in performance =(, should be the same in term of FPS.

tried cwsdpmi and "mrttfble wc" - doesnot speedup.

and by experiementing i find out that it doesnot matter how much polygons on screen while they close to "eye" of player it doesnot drop fps.

used "scr_showfps 1" in console to see how much fps i got.

what causes FPS drops i guess:
while scene have far objects, far walls or far polygons, i mean thay FAR from eye of player, fps is drops.

FPS drops can go from Z Buffering being not optimized?
or while video system is busy on doing minification of textures its drops FPS greatly.

if in console you wrote "gl_farclip 99" where 99 is number of some "units" after that distance render will skip rendering geometry, so if that number is smaller the higher FPS i gain.

My guess: FPS drops comes from bad z buffer handling, bad minification algorithm, something else?

No, you can't fix it. I don't know what they do in their driver to fix the issue in Windows. I'm not that good of a hardware hacker. Your best bet is finding an Asus P3B-F motherboard or any later era Intel 440BX Chipset that allows CPUs past 500/550mhz.

Glad to see other people are using the glide3x.dxe's sezero and I worked on over the past few years.

Mario 64 looks for DOS looks neat indeed, but I can't compile the DOS .exe. May you or someone else who has compiled the binary please post a link to download that DOS binary of Mario 64? Appreciated beyond words!
