The Current Intel "Iris" Gallium3D OpenGL Performance Against i965 Mesa, Windows 10 OpenGL

For those interested in more i965 vs. Iris OpenGL benchmarks on Linux, here are some additional Linux data points:

The Iris Gallium3D driver is picking up more wins than in our previous rounds of testing for this experimental open-source OpenGL driver. Additionally, in cases where i965 is still delivering better performance is at least closer between these two Mesa drivers than we've seen in the past. So overall the performance is looking up for Iris but there is still more performance optimizations and maturing needed before we'll see Intel switch over the Linux OpenGL driver default. Nevertheless, it should be interesting to see how Iris matures this year as well as their ANV Vulkan driver. Stay tuned for more benchmarks when further Mesa Git commits warrant some additional tests.
