some games that are 3dfx only,like the first turok and also quake 2,recognizes the glide perfectly.other games that SUPPORTS glide like hexen 2 instead complains that it requires a 3dfx card

Quake 2 and Hexen II doesn't use Glide. Hexen II supplies a 3dfx MiniGL in the folder under the filename of opengl32.dll which should be deleted if you do not have a Voodoo Graphics or a Voodoo2 (Even if you have a Voodoo3)

The retail version of Turok also supports Direct3D.

Official 3dfx drivers do not support Windows XP. Use Amigamerlin's or SuperFurryFurryThing's drivers instead.
