Doom 3 and Tiger

Cafemacs generated quite a bit of buzz with their alleged DOOM 3 test on a Tiger build, saying the perfs were quite a bit ahead of Panther's. Lots of comments in all directions.
So we went ahead and asked a beta tester to run some benchmarks for us, so we could compare them with the results our Gui92 gave us under 10.3.8:
- 800x600 w/o Aniso w/o shadows : 50.9 FPS
- 800x600 w/o Aniso w shadows : 38.3 FPS
- 800x600 w Aniso 4x w/o shadows : 47.7 FPS
- 800x600 w Aniso 4x w shadows : 37.1 FPS
- 1024x768 w/o Aniso w/o shadows : 41.7 FPS
- 1024x768 w/o Aniso w shadows : 29.6 FPS
- 1024x768 w Aniso 4x w/o shadows : 38.2 FPS
- 1024x768 w Aniso 4x w shadows : 28.1 FPS
Our beta tester friend then ran the same benchmarks on the most recent seeded build of Tiger:
- 800x600 w/o Aniso w/o shadows : 52.2 FPS
- 800x600 w/o Aniso w shadows : 40.2 FPS
- 800x600 w Aniso 4x w/o shadows : 46.4 FPS
- 800x600 w Aniso 4x w shadows : 35.4 FPS
- 1024x768 w/o Aniso w/o shadows : 44.2 FPS
- 1024x768 w/o Aniso w shadows : 31.6 FPS
- 1024x768 w Aniso 4x w/o shadows : 37.4 FPS
- 1024x768 w Aniso 4x w shadows : 27.9 FPS
Both results are more than similar, dare we say identical. So, no need to think Tiger will help for DOOM 3, coz it won't.
