An Initial Look At The Intel Iris Gallium3D Driver Performance

One of the most exciting developments in the open-source Intel driver space this year was the Iris Gallium3D driver taking shape as what's destined to eventually succeed their "classic" i965 Mesa driver. With Iris Gallium3D maturing, here's a look at how the performance currently stacks up to their mature OpenGL driver. The Intel Iris Gallium3D driver is designed for Skylake (potentially Broadwell too) support and newer generations while being a forward-looking driver and utilizes their mature NIR compiler support. Iris holds much more performance potential than their classic Mesa driver albeit the developers haven't really taken to performance optimizations yet but rather getting the driver up and running, eliminating test suite failures, and getting to the point of feature parity with the i965 driver.
