Overall, these results aren't too different from what we've seen in past Windows vs. Linux OpenGL comparisons when using NVIDIA's official drivers. For the most part, the performance is very close between Windows and Linux. Where the performance deviates generally is in the CPU bound scenarios (OpenArena, Xonotic with low image quality settings, etc) where Ubuntu with the NVIDIA driver tends to come out ahead, particularly on higher-end graphics cards. Coming up next will be the Windows 10 Radeon Software vs. Ubuntu 16.04 AMD GPU-PRO driver results.
