Windows 10 vs. Ubuntu Linux With Radeon / GeForce GPUs On The Latest 2018 Drivers

For the Dota 2 results, first up using OpenGL on both platforms... The RX Vega 64 again shows its strength on Windows, making it look like there still is more Vega optimizations needed by the AMDGPU+RadeonSI driver stack on Linux. The NVIDIA results for the GTX 1060 were comparable between operating systems while the GTX 1080 Ti ended up being 39% faster on Ubuntu.

Dota 2 with Vulkan on both operating systems meanwhile showed the Radeon Software Vulkan driver being much faster than the common "RADV" Vulkan driver on Linux. With the NVIDIA drivers meanwhile the GTX 1060 was comparable between platforms while the GTX 1080 Ti again was a fair amount faster on Linux.

Portal obviously is very much playable with any modern driver/GPU should you still be interested in this Valve game... But for what it's worth, the Windows results on Radeon were slightly faster than Ubuntu while for the GTX 1080 Ti the performance was about the same between operating systems and on the GTX 1060 was slightly faster with Windows 10.
