Linux / UNIX: Test Graphical Performance ( 3D Acceleration / FPS )

How do I test my graphical performance including FPS under Linux operating system? How do I find out if 3D acceleration support is included or not under Linux?

You need to use the glxgears program is a port of the “gears” demo to GLX. It displays a set of rotating gears and prints out the frame rate at regular intervals. It has become quite popular as basic benchmarking tool.

Open a terminal and type the following command:
$ glxgears

Above is a result from my Quadro FX 570/PCI/SSE2. FPS rate < 1000 means you either lack 3D acceleration support or driver is not loaded.

    my system crashed and I reinstalled with the CD. I can’t get past the window for “user name and password”? What can I do? I have tried every combination of of passwords and nothing is working!

    Phoebe, boot system from CD (rescue mode) and remove password from /etc/shadow or try single user mode. It depends what OS have you got.

    Also, If you have vblank sync enabled because of your shitty nvidia card (or other reasons) this locks it to 60fps or whatever your vertical refresh rate is.

      Hello, what does it means? I have 60 FPS, but with a sentence that sounds very much like whatever you are speaking about:
      “Running synchronized to the vertical refresh. The framerate should be
      approximately the same as the monitor refresh rate.”

      Thank you,
      Antonello (intel+ATI i5 laptop, ubuntu 12.10)

        Turn off synchronization and you will see the real speed (FPS):
        vblank_mode=0 glxgears

    Hello! I got a problem.

    When I was using my X server without installing my gpu’s driver, glxgears showed a performance about 300 FPS, after installing my gpu’s driver, performance is the same.

    My gpu is nvidia geforce 7300.

    Anybody knows how to fix that problem?<

    Thanks!
