It seems people are going nuts trying to change this and that. while some things are tweakable and people can tweak shaders and whatnot, maybe even hooking into it (not sure how legal), half the things people have tried just dont do anything. Its for the most part psychosomatic.
I straight up DELETED the graphics card compatability files, lightmass files and everything else I could find and the game didnt even care that they were gone... it changed nothing. Not just the local copies, I deleted the default copies as well as the ones left in by the crew with comments intact.
what weve got is what weve got and if its not in the game/engine settings it prettymuch doesnt exist.
