Commen= t # 5 on bug 11124= 0 from Sylvain BERTRAND 
On multi-core cpus, better use the performance cpu freq govern=
or.
Some load profiles may be badly managed by the on-demand cpu freq governor.
Due to the load profile, some cores may not get enough load to be switched =
to
their highest frequencies (which is critical for realtime game performance).

I did notice significant fps loss with the on-demand cpu governor with some=
 of
my dota2 configurations running on a 8-cores 4.7GHz (FX9590).

This is a pb for lambda users who don't want to know anything about cpu freq
governors.

Multi-threaded games must be aware of the pb and warn the users about the
cpu governor settings (this is true on any OS).
