Performance difference with graphics?

[fliptwister]

I recently reinstalled 10.10.2 on my dual boot computer and I'm wondering if I have an issue with my setup or if poorer graphics performance on OS X is just inherent of drivers, os, etc.

I have a GTX 970 that I'm overclocking to 1,468 MHz core and 7,830 MHz memory, a i5-4690K @ 4.9 GHz, and I'm running my ram at 2,400 MHz. I tested some cross platform benchmarks on my machine with exact same hardware and tuning. These are with most recent drivers for both operating systems.

In Cinebench I get the following:
108.82 fps Open GL OS X (10.10.2)
152.63 fps Open GL Win 8.1
That is about 40% better performance on Win 8.1.

With Unigine Heaven Benchmark at 1920x1080, quality - ultra, Tessellation - Extreme, and 4XAA.
51.1 fps Open GL OS X (10.10.2)
64.3 fps Open GL Win 8.1
70.4 fps DX11 Win 8.1

1,286 score Open GL OS X (10.10.2)
1,619 score Open GL Win 8.1
1,774 score DX11 Win 8.1

With Unigine Valley Benchmark at 1920x1080, quality - ultra, and 4XAA.
56.2 fps Open GL OS X (10.10.2)
68.6 fps Open GL Win 8.1
79.4 fps DX11 Win 8.1

2,351 score Open GL OS X (10.10.2)
2,871 score Open GL Win 8.1
3,320 score DX11 Win 8.1

Are other people that are dual booting seeing these kind of differences in graphics performance?

Thanks!

edit: I should mention that I'm running a Samsung 830 SSD for OS X and a Samsung 850 Pro SSD for Win 8.1. The SSD for Win 8.1 is a faster drive but I would not imagine this would make a big difference.

Interesting article. Thank you!

The article has similar performance difference to me in Portal. The article has fairly close performance in Call of Duty 4 and Cinebench. I'm certainly not seeing close performance on Cinebench. It does not look like they are using nvidia web drivers though and that was 4 1/2 years ago.

I'm going to see if I can track down any more recent articles.

Has anyone out there run Cinebench of both of their OSs?
