AMD Catalyst AI Performance With "Tonga" On Ubuntu Linux

Along with today's R9 285 GPU scaling tests from Ubuntu, other Linux graphics tests I ran from the AMD Radeon R9 285 GCN 1.2 graphics card is a check whether to see Catalyst AI is doing much on Linux.

In the past I've found the Catalyst AI feature exposed by AMD's Catalyst Linux driver to be next to useless: AMD's Catalyst A.I. Is Good For Few Linux Games and AMD Catalyst A.I. Useless Under Linux?. But with this latest Catalyst Linux driver (fglrx 14.30 series) and newest graphics card (R9 285) I decided to run the OpenGL tests again on Ubuntu 14.04 LTS.

Catalyst AI can be enabled from the AMD Catalyst Control Center Linux Edition (AMDCCCLE) and defaults to enabling it with the "standard" level but it can be disabled entirely or also set to the "advanced" level. Catalyst AI is supposed to improve the performance for some games with AMD graphics by taking rendering short-cuts or other "secret" optimizations to improve performance -- Catalyst AI isn't supported by the open-source AMD Linux driver.

Once again when testing Catalyst AI on Linux, I didn't find much (any?) performance difference.
