Resolution
Red Hat does not require 3D or GPGPU functionality or performance to be tested for system certification.
This system was certified using the Intel i915 video driver.
For systems with "Switchable Graphics" it is possible to run an OpenGL application on the discrete GPU by first exporting the environment variable "DRI_PRIME=1".
