On dx10+ cards this should work. If you are having this problem on a Geforce 8
or newer, or on a Radeon HD 2000 or newer it is probably a different bug. On
older ones it has improved a bit, but not enough for this game.

The situation is unchanged on Nvidia. We're providing 253 uniform for the
game's use, 2 are left for the compiler's own use and 1 is for our position
fixup uniform. If you have a geforce 6/7 card use ARB shaders for this game.

On AMD cards we have removed the hack that reserved something like 8 uniforms
for the compiler and are doing the same thing we're doing on Nvidia now. So in
theory the game has 253 constants available, but needs 255 (256 is the HW
limit).

If you want this to change it is something that you'll have to do yourself. The
hardware is EOL since a long time, so I won't put much time into fine-tuning
this corner case, and I believe the mesa driver devs won't do it either.

Again, if you're on a dx10 card and the game doesn't work (it does for me with
it's highest quality Shader Model 3 shaders) then the problem is something else
and I am happy to investigate.
