P-State/CPUFreq CPU Frequency Scaling Tests For Radeon/NVIDIA Gaming With Linux 4.16

With Mad Max on Vulkan the performance is roughly the same across tested platforms with the exception of the CPUFreq powersave governor. Feral has used workarounds within Mad Max to ensure less erratic performance if the Linux system is using a less than ideal governor choice.
Here's a look at how the system power consumption was on the different systems during the benchmarking process. CPUFreq powersave obviously had the lowest AC system power consumption but with horrible performance. The only other real outlier was the CPUFreq Schedutil driver often dipping slightly lower with its power draw although the average power draw was right in line with the others.
