4. Performance with the proprietary driver, set to use application settings, Tear Free enabled (typical, all releases):
I could not see any difference in the video tests between this and when the settings all at high quality. Obviously those applications were being allowed to use optimum values and Tear Free was key.
TF2 and GLMark2 frame rate increased back to 60FPS. But that's really not what the gamers will want to hear.
5. Performance with the proprietary driver, set to use application settings, Tear Free disabled (typical, all releases):
I could see some hints of tearing in videos. Or was it my imagination?
But this where the game and GLMark2 got to really shine -- at least in demonstrating the computing power of the GPU. Tear Free and overriding application settings seem to knock the wind out of them as far as their computing performance.
TF2 was much faster (in terms of frame rate) and the GLMark2 score was pretty good at 2077 -- or about 2000FPS faster than my 75Hz monitors can produce. I don't know if gamers would find that acceptable for any sort of bragging rights or not.
Max observed temperature was 65%, max fan speed was 55% and load hovered near 100%. Obviously it was working harder than it was before.
Unfortunately, this did cause some significant disruption in the smoothness of some of the DE eye candy, like window movement, etc.
