Then I bought a 3DFx Voodoo card and started using Glide and it was night and day. I had something up the first day and every day thereafter it seemed to get more and more capable. That was a lot of fun.
In my opinion, Direct X was what killed it most. OpenGL was well supported on the Voodoo cards and Microsoft was determined to kill anyone using OpenGL (which they didn't control) to program games if they could. After about 5 years (Direct X 7 or 8) it had reached feature parity but long before that the "co marketing" dollars Microsoft used to enforce their monopoly had done most of the work.
Sigh.
Intel would offer upto(?) (cant recall if it base, set, or upto) $1 million in marketing funds if me and my buddy did our objective and subjective gaming tests between the two looking for a subjective feel that the games ran better on Intel.
The objective tests were to determine if the games were actually using the SIMD instructions...
