Forced Vsync in Ubuntu?

TwistedFury · May 2, 2014

I have my games set to not use Vsync (Minecraft on Max FPS, etc) But it's still limited to my monitors refresh rate (60) is there a setting I need to toggle to disable Vsync? I just installed this OS, do I need to install the Intel HD Graphics driver via Synaptic?

It would be helpful to install the Intel HD Graphics driver. This link will tell you how to do exactly that:

You should also install vaapi from this page:

https://launchpad.net/ubuntu/+source/intel-vaapi-driver

...or this page as your hardware requires:

https://packages.debian.org/wheezy/libva-intel-vaapi-driver

You should also have installed CompizConfig and CompizConfig Settings Manager from the Software Center or the command-line.

It might also be helpful to look at this information:

Setting resolution changes in xorg.conf

If the file is not there, you can create it.

Notice how to append the refresh rate:

Section "Monitor"
Identifier "External DVI"
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync
Option "PreferredMode" "1280x1024_60.00"

...with an underscore and 60.00 like so "_60.00". That value can be modified.
