| Summary | frame stuttering in ut2004 |

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.
