Open source drivers force vsync for everything 3D - why?

Use driconf and look under performance tab.

I did that, but there is still vsync. Is it because of Unity? Vsync is turned off in compiz settings.

*bump* I am back using open source drivers in Ubuntu 11.04 temporarily

Here is my .drirc:

Code:

---

<driconf>
    <device screen="0" driver="r600">
        <application name="Default">
            <option name="fthrottle_mode" value="2" />
            <option name="vblank_mode" value="1" />
            <option name="allow_large_textures" value="1" />
        </application>
        <application name="warsow" executable="/home/myname/warsow/warsow">
            <option name="fthrottle_mode" value="2" />
            <option name="vblank_mode" value="0" />
        </application>
    </device>
</driconf>

Frames per second in Warsow is still locked at 60

Alright, I just froze everything, not even REISUB saved me.

*gives up on gaming with open source drivers for another 10 years*

Ubuntu 11.04 is still using 7.10. The difference between r600g in 7.10 and (what will be released as) 7.11 is like night and day. Very much worth the effort to grab from git or by using some unofficial packages.

You still need to manually edit drirc:

Code:

---

<driconf>
  <device screen="0" driver="dri2">
      <application name="Default">
          <option name="vblank_mode" value="0" />
      </application>
    </device>
</driconf>

I added this ppa:

I don't know what driver version I now have, but vsync issues are gone! I didn't even have to run driconf and disable it there.
Unfortunately Warsow can't achieve stable 125 fps yet, even at 640x480 resolution.
