Re: OpenGL performance with Gala


Hi all:

I created a little daemon to set priorities. It's called GAMEd.

You can download and install it just opening a terminal and typing:

    git clone https://github.com/rastersoft/gamed.git
    cd gamed
    sudo make install

Now, to set the priority, just type

    renice_gamed -20

This will set the priority of both Xorg and Gala to -20

Now, each time you enter your session, GAMEd will automatically set the
priority to that value. If you change it again, the new value will be
remembered between sessions.

You can also edit /etc/gamed.conf and add more executables to the list
(like unity or gnome-shell), allowing to use it with other desktops.

Of course, this is just a temporary hack, until ulatencyd gets fixed.

One last note: it seems that the effect in games needs some seconds
before working, so after setting the priority, wait some seconds before
launching the game.
