Windows 10 vs. Ubuntu Linux - Dell XPS Intel Gaming

Dota 2 at 1080p isn't playable for the UHD Graphics 620 on the Dell XPS 9370, but between OpenGL, Vulkan, and Direct3D 11 on Windows the performance was close. With Ubuntu 18.04, the results were just about the same and slightly leaning in favor of OpenGL, albeit by just a single frame average.

The aging Portal game is easily playable with the UHD Graphics 620 and here we found the Windows 10 performance to be measurably better than Ubuntu 18.04 LTS.

Unigine Superposition saw around the same performance between OpenGL and Direct3D 11 on Windows. In this more demanding graphics benchmark, the Windows performance was noticeably ahead of Ubuntu 18.04.

Unigine Valley was also faster on Windows over Ubuntu 18.04.

As we have seen with the X-Plane 11 flight simulator on other graphics cards/drivers, the X-Plane performance tends to be better under Linux than Windows.

It was mostly a battle of the snails with this UHD Graphics 620, but for those curious, these are the numbers while waiting for the more interesting system/CPU benchmarks and power data, etc in the days ahead. At least the UHD Graphics 620 are capable enough for a modern composited desktop on either platform and even for driving an external 4K display -- more on that in my Dell XPS Linux review itself.
