(In reply to Marek Olšák from comment #2) > r300g on RC410 uses software emulation for vertex shaders and clipping (the > same code as llvmpipe), because the hardware doesn't have any vertex > processor and clipper. Can't the chip do guardband clipping? I thought all radeon chips (starting from r100) could do this, regardless if they support hw tnl. I could be wrong though (and I wouldn't know how large the guardband would be, and certainly draw's handling of guardband if you enable it is a bit lacking, since hw has fixed limits whereas draw will use a guardband twice the size of the viewport).
