Haha the whole thing was from sezero. I didn't even realize it was him who had the same problem 10 years ago. That's rather funny.

I have to eat some dinner and such, but I'll be back later and we can discuss it more. Thanks for finding this issue on the mailing list... Was there subsequent replies to it?

I tried to get in touch with daniel borca, but have not heard replies though his emails still work. His old website says around 2005-2006 (forget specifically) he was hired at bitdefender. I wanted to send him an email so he could know about how his work ended up panning out like 10-15 years later …

Having the MMX and other friends help a very minute amount (literally 0.5-1.0 difference in it's favour). It may be worth keeping them though since they won't be optimized away. It's hard to say what's the best solution for something so tricky. I don't think the DMesa/fxMesa crew really knew the …

Also, in the timedemos there is ZERO difference between these flags. SLI or not, they produce exactly the same results down to the tenth digit.

You have very interesting findings. On glide3 makefiles I've seen prior, they have this: ifeq ($(USE_X86),1) CFLAGS += -DGL_X86 OPTFLAGS ?= -O1 -ffast-math -mcpu=pentium else CFLAGS += -DGLIDE_USE_C_TRISETUP OPTFLAGS ?= -O1 -ffast-math endif I recall that this is documented (maybe a code comment?) …

Well, I could get nuts and try to find out specifically what switch it is... but considering there isn't even a performance degradation it's probably not worth the effort. I've noticed in general that playing with optimzer flags usually does no good. Even GCC warns about it. For small, simpler …

Things get more interesting in that my gcc4 builds of glide3x (no matter which version) had proper working SLI on voodoo 5. On sezero's builds I usually got corrupt screens in SLI mode. After much fiddling around I think I found the issue... Compiling with -O1 instead of -O2 -ffast-math in gcc3 …

I'm going to upload a new version shortly that has the few small changes to CVGs source tree (added stipple alpha support). I want you to test that compile for me too then.

There's a 0.6 fps difference in running the timedemos so the optimizations are doing something.

technically... cvg only cares about usign MMX and 3DNOW. The others are redundant.

Wow on real hardware it's actually quite a bit faster. I can actually play Q1 properly on the p1 mmx without a lot of shitty framerate drop.

Yes your compile works. Can you do a compile with the make flags I just sent you make -f Makefile.DJ FX_GLIDE_HW=cvg USE_X86=1 USE_MMX=1 USE_3DNOW=1 USE_SSE=1 USE_SSE2=1 Also what is your build environment.

Okay. Yeah I just need the glide3x.dxe. It needs USE_X86=1 for CVG apparently according to makefile

It's more like rather annoying. There are very subtle quirks all around between testing these versions. CVG (Voodoo 2) hard locks on real hardware with the last glide3x version and sezeros for me when I build it. Can you try to build it from QDOS's mesa51 branch or Q2DOS (master branch) for me? …

I got DMesa 5.1 working which has some bug fixes, and specifically, it supports the gl_extensions properly according to the changelog. I had some problems in SLI so I didn't use it yet, but the last version of glide3x from the development branch on sourceforge appears to fix these issues. Have to do …
