NVIDIA Linux Driver 2015 Year-in-Review

The GTX 780 Ti performance seemed to improve bit by bit with the tested driver releases while the GTX 980 didn't indicate any performance change for BioShock Infinite between the 346 and 358 release streams.

The DiRT Showdown benchmarks indicate there being measurable performance improvements for both the GTX 780 Ti and GTX 980 between the 346 and 358 driver series.

Metro Last Light Redux saw a boost at the end of 2014 between the 340 and 346 driver series, but for the GTX 980 not working properly on the 340.65 release, it's unknown if that would carry over to other hardware. Between the 346 and 358 releases, there was no measurable change in performance.
