Yeah... that and the Iron Lake result have been nagging at the back of my mind. My suspicion is that a lot of the shaders from shader-db that benefit from this patch use GLSL 1.30 or later. As a result, they are not built on GM45 or Iron Lake... but I haven't dug into it. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
