             Bug #: 50360
           Summary: flightgear has absymal performance with the llvm
                    shader compiler
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: aaalmosss@gmail.com


I get ~3 fps with the LLVM compiler, while I get ~20 fps with `R600_LLVM=0
fgfs`. The only setting on the 'rendering options' dialog that affects
framerate is 'material shaders', when it's off, I get ~50 fps with both
compilers.

Other games perform around the same with the two compilers.

Yes, it helps a lot. Now I get ~40 fps with both compilers.
