            Bug ID: 96790
           Summary: frame stuttering in ut2004
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: network723 at rkmail.ru
        QA Contact: dri-devel at lists.freedesktop.org

My hardware: HD7950 & Phenom II x6 1090
The problem: intensive frame stuttering and frame rate drops below 30 fps while
playing UT2004. Drops usually happen when there is intensive shooting, but it
may also happen on maps with complex geometry.

Also, in-game fps counter shows 'avg fps' about 90-200, with rare jumps to
300-400 fps, even with vblank_mode=0 set. 64 bit version of the game on Windows
shows stable 300+ fps with OpenGL renderer.

I wonder if this may be related to AMD CPU, since various test results on
Phoronix show much greater performance (up to 5 times) with Intel CPU and same
GPU.
