On a short test with a Voodoo2
using FX_EMULATE_SINGLE_TMU and
FX_DONT_FAKE_MULTITEX
I got the following results:
1) (best) real multitexture
2) single TMU no faking
3) (worst) single TMU faking multitex
The difference between the steps was
5-10 % in framerate.
All tests were run with a texture setup
which fit into the onboard memory.
(obviously it would be easy the get really
bad results with a the single TMU configs
using a larger texture set)
