Various tweaks to improve the gaming experience in Linux
This is especially useful to launch automatically when you run a (Steam) game by adding it to the game's "Launch Options" in Steam -- right-click the game in the library list, click "Properties", click "Set Launch Options...".
eg:
$HOME/bin/linux_gaming_tweaks.sh start; %command%; $HOME/bin/linux_gaming_tweaks.sh stop
.
Make sure to chmod +x linux_gaming_tweaks.sh
before you try that.
