I believe the PPro was quite strong in Quake and Q2.

^ only with Fastvid (write combining) enabled, and then there's the whole unobtanium luxury of a cpu it was in its time that makes itself too prohibitive for the consumer market. might as well list all the server processors for each year and eventually revise history that everyone was using a Ppro and a Intergraph 3d card in 1995 and 3dfx's success being a conspiracy and Intel is super underrated for their MMX 3d chip and Quadro being launched as an early beta of the Geforce256
