Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming
Written by Michael Larabel in Display Drivers on 22 June 2014. Page 5 of 5. 10 Comments

To no real surprise now, Warsow didn't see any measurable improvement in the frame-rate for Warsow on the NVIDIA GeForce GTX 760 but its CPU usage was measurably higher.

Xonotic saw improved performance with NVIDIA's __GL_THREADED_OPTIMIZATIONS in the 337.25 driver for the GTX 760, but there was much fluctuation in the frame-rate between the multiple trial runs carried out by the Phoronix Test Suite.

It's understandable that the OpenGL threaded optimization feature isn't enabled by default given that it won't benefit all OpenGL games/applications and for some can decrease performance while causing greater CPU utilization. See our earlier __GL_THREADED_OPTIMIZATIONS information if you want to play around with this NVIDIA proprietary driver feature on your Linux PC.
