Yes, software-rendered Mesa for DJGPP is ghastly slow, at least on the
5x86/133 I tried it on about a year ago. I think it's still comparable to
Microsoft's opengl32.dll though (where I got 14fps on a 233 drawing a
gourad-shaded 'U' with 6 vertices.. ugh!) The texturemapped & fogged
"hallway" example with Mesa ran about 1-2fps on the 133, if memory serves
me... which made me start working on a software-rendering library with
Allegro instead.  (sorry, it's incomplete, buggy, and I'm not gonna work on
it anymore now that I have an accelerator..:( ) I don't know of any other
ways though... maybe use Allegro for software-rendering and Mesa's opengl
for hardware?  That would take a lot of coding and a solid knowledge of 3D
math and coding techniques to implement though..
