CONFIG_HZ_PERIODIC
# CONFIG_HZ_PERIODIC is not set

Ubuntu seems to not set this option on the desktop version. Also I'm noticing
this performance issue rarely. For example I remember to have seen this issue
some time ago on Loot Heroes and some other games I don't remember well
anymore. They worked much better from changing all 6 cores to the performance
governor (was ondemand with up_threshold on 11 before). And a short time ago I
have noticed this performance drop on Bullet Heaven 2 but it was only a short
test. If I could I would simply set up_threshold to 1 to be sure to really
eliminate any race condition here as much as possible.
