Well, three issues here:

1) GLIDE is 'going away' - it's evident in the Windoze world that
   3Dfx is finally losing interest in it.  It had to die sooner or
   later because it doesn't suit hardware T&L - and *eventually*
   3Dfx will wake up to the realisation that if they don't get their
   act together and produce a machine that can do 20M triangles a
   second in hardware, they are out of the business.

2) If you write in GLIDE, your program will only be able to run on
   3Dfx hardware.  OpenGL is portable and will work on lots of different
   hardware and under lots of operating systems.

3) If you think you can write the higher level transform/clip/lighting
   code better than the guru's who wrote and optimised Mesa - then GLIDE
   will certainly be faster than OpenGL/Mesa because (on 3Dfx machines)
   Mesa runs on top of GLIDE.  However, if you are not a truly great
   optimisation nut with *WAY* too much time on his hands - you are
   probably better off using OpenGL/Mesa.

Conclusion:  Don't use GLIDE.
