OpenGL multithreading in Mesa is ready for wider testing

A Mesa developer wrote into the public Mesa-dev mailing list to ask for testers of OpenGL multithreading in Mesa so that they can grow the whitelist of games that will use it.

The OpenGL multithreading can actually be used by all Mesa drivers, not just AMD. So anyone using an up to date version of Mesa-git should be able to get in on the testing. They went with a whitelist since it can actually hurt performance of some games. Games that are limited by CPU performance are the ones that will benefit from the OpenGL multithreading.

The mesa developer gave an example of some games they found to benefit already:

QuoteAlien Isolation: +60% (it varies depending on the location, increased since
Grigori's commits)
Borderlands 2: +50% (it varies depending on the location)
BioShock Infinite: +76% (benchmark)
Civilization 6: +20% (benchmark)

They also specifically asked people to test a few like Civilization 5, which already has patch to enable it as someone has already tested it!

You can find the full mailing list entry here, with instructions on how to proceed.
