Which hardware/driver are you using under Linux? I just became aware of a hardware limitation in several drivers (mga, r128, savage). They can do multi texturing, but if multi texturing and projective textures are used at the same time they fall back to software rendering. For example quake2 gets really slow on the savage if you enable multi texturing, because it uses a projective 2nd texture for lighting effects.
If multiple passes are used then there is no need for software fallback, because each pass uses only one TMU with or without a projective texture.

The same method, and with no > alteration to the code, with nVidia drivers in linux shows mtex is faster.
