@ -12,26 +12,27 @@ The design has a clear cut abstraction between the host daemon and library (\fBg
|
||||
|
||||
\fBGameMode\fR was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is intended to be expanded beyond just CPU governor states, as there are a wealth of automation tasks one might want to apply.
