Don't forget the co-marketing from Intel's DRG (dev relations group) (the group I worked in) which started in ~1995 or so for game optimization dev on SIMD and, later AGP, openGL and unreal engine (our lab had some of the very first iterations of this - and NURBs were a major topic in the lab especially for OpenGL render tests etc. (if you recall the NURBs Dolphin benchmark/demo)
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...
