    Ok, so this is a mesa problem. But then I use the git version which might simply not be ready yet. But then indeed the phoronix benchmarks are rather meaningless.

      Their own link shows they're wrong:

      The built-ins suffixed with “Lod” are allowed only in a vertex shader.
      Lod in the fragment shader is not a part of 1.2. It must be specifically enabled, either via the gpu_shader4 extension (not fully supported by mesa IIRC), or by GL_ARB_shader_texture_lod, which is fully supported.

        Thanks curaga. I'll report it.

          I know this is way off topic but there is also an ogre3d based fork called Stunt Rally http://code.google.com/p/vdrift-ogre/ that might be of interest for racing game fans. It might be of interest for Michael too as another possible benchmark.

            Good point, didn't know about the "only by appointment". I just figured IRC would be fastest and I wouldn't have to create an account on their forum. Didn't think about github though, good idea!

              That one looks awesome! I used to play a game similar to it, 4D Racing, in the mid-nineties. Great game! =)
