SM3 requires the ARB_shader_texture_lod functionality though.
Yeah, I guess that's the driver's fault, since the hardware should support it, AFAIK. Anyway my hack was intended just to investigate whether this was the root cause of the bug or if there is something more.
BTW, ARB_shader_texture_lod is not reported on my GeForce GTX 460 either (while fglrx reports it on my Radeon), but being a DX10+ class GPU it has EXT_gpu_shader4 and that is still good for our purposes.
