New Revision: 7378

Modified:
   trunk/darkplaces/gl_rmain.c
Log is attached.
glsl doesn't allow dividing by zero (result is undefined, although sane on nvidia), so...
-"      color.rgb = SceneBrightness / (ContrastBoostCoeff + 1 / color.rgb);\n"
+"      color.rgb = color.rgb * SceneBrightness / (ContrastBoostCoeff * color.rgb + 1);\n"
also gains some fps apparently (7600GT here)
Weirdly, *= seems to be by 3fps slower than using = and *
