--- Comment #2 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-28 09:44:14 --- Watch the console for glsl warnings. The difference between a Geforce6/7 and a Geforce8 can be really big. In short the latest dx9 games stress the shader engine to the max capabilities of shader model 3.0. Lots of games consume about the maximum number of 'constants' (uniforms). To emulate differences between d3d and opengl we are 'eating' some of the constants. This causes less constants to be available to the game and if the game was nearing the limits this can cause serious problems. Quite a number of modern games are affected by this (including UT3). Not much can be done about this. Geforce8 cards offer a lot more constants (because SM4.0 requires this) and for that reason don't see these issues.
