    Default Tweaks to improve gallium on RV770?

    Hello,

    Are there switches to improve gallium performance on a radeon 4890? Perhaps stuff that can be turned on that is off by default or something like that.
    This is some of my glxinfo:
    Code:
    $ glxinfo
    direct rendering: Yes
    server glx vendor string: SGI
    server glx version string: 1.4
    server glx extensions:
    
    client glx version string: 1.4
    client glx extensions:
    
    GLX version: 1.4
    GLX extensions:
    
    OpenGL vendor string: X.Org
    OpenGL renderer string: Gallium 0.4 on AMD RV770
    OpenGL version string: 2.1 Mesa 7.11.2
    OpenGL shading language version string: 1.20
    Thanks.

    The best way to tweak things would probably be to use the latest stuff from git, and enable 2D color tiling. You might also want to try the HiZ patches, but those seem to be a bit unstable.

    If you don't mind flickering, turn off SwapbuffersWait (xorg.conf) and set vblank_mode to 0 (drirc).
