NVIDIA 2013 Linux Graphics Driver Year-In-Review
Many features were added this year to the NVIDIA Linux driver, including some performance enhancements, but no widespread changes across the board -- at least from this testing and the other tests I've done between driver releases in the months prior. For Source Engine games, the 310 release brought many of NVIDIA's optimizations like last year with the threaded OpenGL optimizations.
There wasn't anything too exciting about the Unigine results either from this GeForce GTX TITAN benchmarking.
At least on the bright side there weren't any regressions affecting this Kepler GPU's OpenGL performance.
