NOTES:

As noted in the Heaven Benchmark, I have the Nvidia settings to 'Prefer Consistent Performance' instead of 'Prefer Maximum Performance' in an attempt to avoid thermal-throttling.

Most people online agree that Heaven is a much more finnicky and stressful test than even 3DMark, and it's much easier to get higher numbers in Valley.
That being said, apparently Valley uses more VRAM. This card has 4GB, so maybe that alone will push the frames.

And sure enough, it does, to a degree.
But before we discuss results, let's discuss temperatures.
As seen in the Heaven benchmark, OpenGL had higher temps sitting around 75C - 78C. Note: It didn't ever hit 79C, which it frequently did on Heaven.
For DX11, the average was somewhere from 73C to 75C.
But near the end of the benchmark, it got throttled. It was at approximately 11.9 FPS average when it happened. Down to its 3FPS, for a couple seconds, then the temp spiked down to 68C (and quickly ramped back up) while the frames went back to normal.
Although I didn't actually catch it in the act, I suspect OpenGL did the same thing, leading to the very low Min. FPS numbers.

Strange that it happened while only at 75C though. I typically caught it only around 79-80 previously, so perhaps the GPU is falsely reporting because of the benchmarking software? That would also explain why it never hit 79C while Heaven was basically operating at that temp. during its last few scenes.

In any case, to the numbers comparison. OpenGL got a higher score yet again, and will be the base score to relate from.

			[OpGL]			[DX11]	[Result]
Score: 		495		vs.		486		(+1.8%)
Avg. FPS:	11.8	vs.		11.6	(+1.7%)
Min. FPS:	2.8		vs.		3.0		(-6.7%)
Max. FPS:	20.2	vs.		19.2	(+5.2%)
[BONUS:]
Fix. FPS:	11.9	vs. 	11.8	(-1.8%)

Note the bonus: If the frames did not throttle right at the end, it would have beat OpenGL's average framerate.
At the end of the day, we can arrive at mainly the same conclusion. OpenGL can pump larger numbers at the cost of stability and power consumption.
That being said, these numbers are incredibly close to one-another, less than 6% delta for each individual result.
Perhaps it doesn't make a difference.
