I was there, 3000 years ago, the smooth textures in Quake & NFS, and the lighting effects in Unreal and Quake 2.
Tomb Raider had Glide too. So perfectly pointy.
I have the fondest memories of those days & 3Dfx as a brand. I still have my Voodoo 2s (2×12MB) connected in SLI, I should get them a better display (case?) actually.
