--- Comment #4 from Michel Dänzer michel@daenzer.net --- Looks like Xonotic uses derivatives with GLSL 1.30, which radeonsi doesn't implement yet, so it falls back to dummy shaders:
warning: failed to translate tgsi opcode DDX to LLVM Failed to translate shader from TGSI to LLVM EE ../../../../../src/gallium/drivers/radeonsi/si_state.c:1951 si_shader_select - Failed to build shader variant (type=1) -22
Maybe you can work around this by disabling / lowering some settings in Xonotic, or you could try the WIP patches from http://lists.freedesktop.org/archives/mesa-dev/2013-June/040406.html and http://lists.freedesktop.org/archives/mesa-dev/2013-June/040412.html .
