Windows 10 vs. Ubuntu + Linux 4.7 + Mesa 12.1 Intel OpenGL Tests
Xonotic continues to show a very radical performance difference between the Intel Linux Mesa driver and Intel's proprietary Windows driver. With the other GPU drivers we tend to not see as radical of a performance difference between the two operating systems.
The GpuTest results for these synthetic micro benchmarks show Linux performance numbers still well below the Windows 10 driver.
