    Default According to glxgears I don't have 3d acceleration?!

    I run Gentoo x86. Direct rendering is on and I can play games like ETQW fine. However glxgears shows strange results What does this mean? And how can it be fixed?

    $ glxgears
    Code:
    303 frames in 5.0 seconds = 60.463 FPS
    299 frames in 5.0 seconds = 59.795 FPS
    299 frames in 5.0 seconds = 59.795 FPS
    299 frames in 5.0 seconds = 59.795 FPS
    299 frames in 5.0 seconds = 59.796 FPS
    $ glxinfo | grep rendering
    Code:
    direct rendering: Yes

    First, ensure that you do not have sync-to-vsync forced on (use amdcccle). You can also change your refresh rate to 75 Hz to get a 25% performance increase .

    Finally, try to be less smart (this is looks like gentoo issue than your issue). Options like TexturedXRender are in-development, non-public interfaces. Using the options directly is unsupported. The supported options are configured via the UI - amdcccle/aticonfig.

    Where can I check the sync-to-vsync settings? And where do I configure my refresh rate? I have those render options enbled because otherwise movies won't play Thanks in advance!
