Can users set a flag (e.g. environment variable) that will rather do
"nothing" than hitting software fallbacks?

Disable "projectors" in the UI.

The game actually is quite playable on a G450 + 1 GHz CPU with the D3D
renderer here.

UT2003's D3D renderer respects the D3DTEXOPCAPS_MODULATEALPHA_ADDCOLOR caps
bit and overrides the MaxSimultaneousTextures caps bit to 2 as the driver
lies about it.

FWIW, a G450 is below minimum system requirements and I'm curious to hear
how well cards like the Radeon 8500, which currently is the fastest DRI
accelerated card out there if I'm not mistaken, handle running the game.
