Finally i got a working(mismatched)SLI working on a pentium 4 2.66  with koolsmookeys drivers.Messiah from GT Interactive(Interplay)works on it.
Turok 2 ...nothing happens(uses glide 3 but doesnt work)
Tombraider II (Why i dont see the second device,too choose wich card u wanne use)in setup of it.
blood II...dont see the second device neither...zzz
On my Pentium III 1000 mhz these games runs with no problem(win 98 on it)

On XP Voodoo 2 support is limited to OpenGL and Glide, unless you're using LegendgrafiX drivers, but good luck getting those to work. This is why Tomb Raider 2 and Blood 2 don't work, theyre Direct3D games.

But this doesnt explain why a Glide game doesnt work..maybe it doesnt like the most recent version of Glide? I'm not sure.. On the other hand I think some games try to use their own old Glide dll's that don't work. Try copying the new ones from your drivers to the game's directory. It's been awhile since I used my V2s..

Yea. Im not sure about windows xp and 3dfx cards. On win 98 sometimes the 5500 doesnt even like to run some games in glide but runs d3d just fine. Just trial and error maybe.
