Bug #: 53261 Summary: [i915g] Performance regression in git Classification: Unclassified Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/i915g AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: jano.vesely@gmail.com
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.
