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

With last week's release of Feral GameMode as a system tool to optimize Linux gaming performance, which at this point just toggles the CPU frequency scaling driver's governor to the "performance" mode, reignited the CPU governor debate, here are some fresh Linux gaming benchmarks. Tests were done with both the CPUFreq and P-State scaling drivers on Linux 4.16 while testing the various governor options and using both AMD Radeon and NVIDIA GeForce graphics cards.
