Windows 11 vs. Linux Benchmarks For Intel Arc B-Series "Battlemage" Shows Strengths & Weaknesses
For some more synthetic tests, FurMark showed roughly comparable performance between Windows and Linux when rendered using OpenGL. But for the Arc B580 there were again exceptions and especially when using the Vulkan renderer with Furmark.
The GPUTest results were mixed when exercising the Intel graphics drivers on both Microsoft Windows and Ubuntu Linux. But at the end of the day there is still clearly much room for Intel Battlemage driver optimizations especially on Linux.
