Perhaps this driver only supports OpenGL 2.1 on these cards? I've thrown in a mix of older AMD cards with OGL 3 support or better. Unfortunately, none of my older NVIDIA cards have anything beyond 2.1. Gonna try the GTX 960 in my gaming rig as a last resort, but still dead in the water with the three AMD cards I have.
UPDATE: The NVIDIA GeForce GTX 960 is not a supported card (EmulationStation UI is SLOW), but Dolphin DOES launch games successfully unlike the AMD cards which just segfault.
@nadenislamarre - Any chance this could help address why Mesa is only offering OGL 2.1 support for AMD GPUs? http://superuser.com/questions/964099/correct-opengl-version-on-a-notebook-with-two-amd-gpus
