OpenGL Threaded Optimizations Responsible For NVIDIA's Faster Performance?

With the recent BioShock Infinite Linux benchmark results and the big Metro Redux graphics card comparison on Linux, a fair number of Linux gamers have been bringing it up in the forums with their hypothesis that NVIDIA's Linux gaming performance wins is due to their driver supporting OpenGL threaded optimizations. Well, that's not always the case, as shown in this article with a __GL_THREADED_OPTIMIZATIONS comparison in many Linux games with different GeForce hardware.
