Wine checks for ARB_shader_texture_lod to enable SM3.0 now, doesn't it?
So using something like MESA_EXTENSION_OVERRIDE="-GL_ARB_shader_texture_lod" would cause it to fall back to 2.0?
We enabled SM3 if ARB_shader_texture_lod is present, but it's not currently a requirement for SM3. I'm seriously considering changing that, but currently disabling ARB_shader_texture_lod doesn't necessarily disable SM3.
