Does anyone with the 256.44 drivers experience any speed improvement when the GLSL trick mentioned above ? I don't (256.44, GF 9800 GE, core2duo @3Ghz), but downgrading to figure out if it's related to the driver version seems a bit complicated :) With my setup I generally get 15-20 FPS ingame. (1920*1080, medium settings + high shaders + ultra textures)
