GameMode is a daemon/lib combo for GNU/Linux that allows games to
request a set of optimizations be temporarily applied to the host OS.
GameMode was designed primarily as a stop-gap solution to problems
with the Intel and AMD CPU "powersave" or "ondemand" governors, but is
now host to a range of optimisation features and configurations, like
tweaking various settings: the CPU govenor, the I/O priority, the
kernel scheduler, the GPU performance mode and gpu overclocking
(NVIDIA). It can also excute custom scripts when launching games.
