Intel Broadwell Iris Pro Graphics: Windows 10 vs. Linux

Lastly for this initial Intel graphics comparison for the day-old Windows 10 are some synthetic tests using GpuTest.

With many of the GpuTest cases, the Intel Windows 10 driver remained faster than the latest Intel Linux driver code.

In the Pixmark tests, the Linux driver on Fedora 22 came out ahead.

There's also some tests that run fine under the Intel Windows 10 driver but not the Intel Linux driver at this time. As a reminder, the Intel Windows driver exposes OpenGL 4.3 and OpenCL 2.0 support while at the moment the Intel driver exposes OpenGL 3.3 (but 4.0~4.1 in the coming days) and OpenCL 1.2.

These results were interesting for our first Windows 10 benchmarks, albeit the Intel Linux driver ended up being a little bit slower than the Intel closed-source Windows driver in many of these OpenGL tests.
