Ryzen 7 CPUFreq Governor Comparison For Linux Gaming On 4.12

While CPUFreq Ondemand is Ubuntu's default, switching over to the performance governor yielded a 15% boost in performance. The schedutil governor that's relatively new and makes use of the kernel's scheduler utilization data showed similar performance to ondemand. The powersave and conservative governors meanwhile led to a decrease in performance.

DiRT Rally also saw a measurable boost in performance going from ondemand to performance (~19%).

Dota 2 with Vulkan meanwhile saw no real change in performance for the Ryzen 7 + R9 Fury system.

The open-source ET: Legacy game meanwhile had roughly the same performance between ondemand / performance / schedutil but dropped off with conservative and powersave.
