Vulkan on NVidia 980Ti

[margalus]

I just did a quick little test between OpenGL and Vulkan using NVidia. Seems it helps out quite a bit, at least with a high end system.. The performance difference is very dramatic. The highs stay the same, locked at 200fps. But the lows are dramatically higher using Vulkan.

Here are some screenshots that show the difference. Settings are completely maxxed, including nightmare shadows and texture and 16xAF. First ones have Vulkan running at 160fps and OpenGL at 95..

This second set has Vulkan at 157fps and OpenGL at 107.

Overall, Vulkan was consistently much higher. I would see OpenGL drop down to the 80's, when playing. The same area in Vulkan it would only drop down to about 115 or so.

This isn't conclusive proof, but it sure as heck isn't anywhere near bad performance. I am very impressed. Of course this all really moot since I run with vsync at 60 hz...

The system:
i7-6850@4ghz
32GB ddr4 3200
EVGA GTX 980 Ti FTW

I had very similar results with my 1070.

i have very similar results as the OP same specs except i have a i7 3930k and evga gtx 980ti classified

1920x1080 resolution and no v-sync

I was just trying my 980 Ti sss with vsync OFF. Did you experience any tearing? is that why you are still using Vsync to 60? I read in another thread that Vulcan seems to perform with no tearing so I just played the last part of a level with out Adaptive Vsync so I could see my Frames and I didnt have any tearing.

I am bummed though that when I saw Alternate Frame Rendering 2 as the default mode I thought they had given us a comparable SLI option like on DOOM 3 and Quake 4. But i was wrong. Still nothing is getting used from my other 980 Ti. I thought they said once Vulcan was enabled they would be able to solve the SLI issue. I guess I dont really care but it would be nice if it worked.

Did some quick comparision, didnt noticed any differance with my i7 6700k and 970. Lastest drivers.
Maybe you only benefit from vulkan in specific scenarios?

I didn't notice much tearing, no. But when you are doing 150+fps it's hard to notice the little bit of tearing there would be.

I still run vsync enabled under normal play though.

Yes. Your PC is GPU-limited both under OpenGL and Vulkan (due to your combination of very fast CPU and midfield GPU), therefore you don't experience a performance boost.
If you'd underclock your CPU to 1GHz and then compared OpenGL and Vulkan, you'd definitely see better performance with the latter.
