  • Disabling VSYNC in Quake2. ***READ***

    There has been some confusion on how to disable waiting for vsync in Quake games.

    You don't need any special registry hacks to make Quake games "not wait for vsync". Just like for any other card, you issue the following commands within Quake2:

    gl_ext_swapinterval 1
    gl_swapinterval 0

    You may have to do a vid_restart after this.

    The command for Quake3 test is:

    r_swapinterval 0

    You see, older Matrox ICD's were ignoring the swapinterval setting and NEVER waiting for vsync. The current ones will wait for vsync unless the game turns it off. This is the correct behaviour, as defined by the OpenGL specification. So now in order to not wait for vsync, you have to use the Quake console commands.

    Yes, as Ant described, that is one way to do it...if you are only concerned with Quake games. The registry approach is another way to do it, and produces the same effect...but applies to ALL OGL, not just Q2/Q3.

      Yup. Basically, Matrox has the support in. Now the ball is in the game developers' court.

      The real soluton is for these game developers to start using the swap_interval extension, so their users don't have to jump through hoops with registry settings, etc. just to get vsync turned off.

      Matrox most likely put the registry "back door" in so that users could enjoy high frame rates, even if the game developer might not want them to

          Gains? how about loses ;(
          I really don't fell like reinstalling the damn SE again but it seems like the only option left. I wonder what will happen if this doesn't help either. And I still get 13.8fps in q3demo1.
