Windows 11 vs. Linux Benchmarks For Intel Arc B-Series "Battlemage" Shows Strengths & Weaknesses
Unigine Heaven as the well known and demanding OpenGL benchmark showed the Linux performance slightly outperforming Windows 11. Not too surprising though given the maturity of the Intel Iris Gallium3D driver and the OpenGL support still being more common to Linux systems than Windows.
With the newer Unigine Superposition benchmark Linux maintained the performance lead at low quality settings but at high quality the Windows 11 performance was slightly faster.
With the Unigine Valley OpenGL benchmark being less demanding, the performance of the OpenGL open-source Linux driver was much faster than the aging Intel OpenGL Windows driver.
