Turok TMark
I was using the good old downloadable demo of Turok. Turok is also only using single texturing, another game that doesn't take advantage of TNT's or Voodoo2's second texture unit. The interesting thing about Turok for 3Dfx products is that you can run Voodoo, Voodoo2 or Voodoo Banshee under Glide or Direct3D, showing the huge difference between these two software interfaces. Comparing the results of the Pentium II with the Celeron results shows that the impact of the CPU performance is MUCH higher within Direct3D (DirectX6 used!!) than within Glide. Glide drops only by about 14%, Direct3D by 30% !!! That is why Intel loves Direct3D and why it doesn't like Glide, Direct3D is much more convincing for buying a new and faster CPU. For us it's another reason why favoring Glide though, which is also a good reason for using a 3Dfx product rather than anything else.
