Description Jan Vesely 2012-08-08 17:35:51 UTC 
I tested OpenArena demo088-test1.dm_71. and the pramerate dropped from 17 to 6 fps. I have seen similar drop(more than 50%) in anholt.dm_68 too.
mesa-8.0.4 runs fine.

I think this might be related to https://bugs.freedesktop.org/show_bug.cgi?id=52405.

I can theoretically bisect, but it is an Intel Atom machine so it will take some time.

Ignore this one, the drop is caused by compiling without llvm.
