This is sad to see. A new benchmark video for Windows and Linux using Dota 2 actually shows Windows doing quite a lot better than Linux.
I spoke to the person who did it on twitter, he mentioned both Windows/Linux were done in borderless fullscreen mode. The Linux Nvidia driver was 367.17, while Windows used 368.25. As for AMD Windows used 16.5.3, while Ubuntu used amdgpu-pro.
I said before plenty of times that Vulkan will not be some magical bullet to bring Linux performance up on par with Windows. There can be problems elsewhere contributing to the performance drop on Linux. It could be X11, it could be a compositor issue, it could be lots of things.
I'm certainly no expert in these issues, but seeing Vulkan perform worse than OpenGL at 4K on Linux was quite disappointing to me. At least in lower resolutions Vulkan was performing better than OpenGL on Linux. The major issue is just how much faster Windows is with Vulkan than Linux.

Quoting: liamdaweI actually see a point here. Your card is powerful and supported AFAIK. It means that you can do the benchmark of DOTA2 just to compare your results with his (I'm not interested in all modes he used, just the best ones from Windows (including Vulkan) and Linux Vulkan/OpenGL. I would be interested to see such a comparison.Quoting: devlandNo one is sensationalising anything. These are the facts.QuoteWhat are your thoughts, any theories?
Vulkan is a new API. So far all performance tests yielded similar results. This was expected and is not news.
Please don't sensationalize the issue. Vulkan will get better in time as will it's implementation by game developers. :)
Quoting: rkfgFrom reddit:I don't see the point, since I have a 980ti, not the 1080 that was tested. Totally different generation.
QuoteMaybe the Linux driver is still not perfect for the 1080 card?
From Phoronix, discussing the latest beta driver:
The NVIDIA 367.18 Linux driver doesn't explicitly mention any Pascal support for the new GTX 1070 and GTX 1080, but I believe that's in there too. The next driver release though should officially mention this new graphics card support.
So that suggests to me that the tested driver (not sure of the Linux version he used, I assume the latest stable) is not great for the 1080.
Liam, you have Windows and you can test the renderer yourself. 980Ti should be supported very well and this concern would be struck out.

Quoting: reaVerI'm still calling for this to be tested on a high performance distro rather than Ubuntu.What, exactly, is a "high performance distro"? Every benchmark I've seen suggests that the performance differences between mature distros is negligible, especially when it comes to gaming.

Quoting: MblackwellTo the above question about borderless window: No, if an application is not exclusive fullscreen it won't set the flag required to bypass the compositor.That's a great point. Running with compositor enabled is a great way to kill gaming performance on most Linux desktops.

Quoting: melkemindI'm actually more surprised Nvidia's Linux drivers already suppirt their 1080 card.
Driver was out in Arch main yesterday. Nvidia 367.27-1.
It's in the changelog.

I think it is worth asking they guy if he can check wether using real full-screen makes any difference, but this is a suspect. With borderless window, there is a ccompositor that can decrease performance, with native full-screen this should not happen. If there is still a significant difference with native full-screen, then we need to look deeper, such as into drivers.

To the people asking about the fullscreen mode used, it was stated in the article:

Yes, which is not the optimal mode to benchmark. We need to know if it did influence the results.

I don't understand, there's more fullscreen than borderless fullscreen?

Well, the options in Dota are Exclusive Fullscreen, Windowed and Borderless Window.

Whenever the term "borderless" is used, it indicates windowed. Borderless fullscreen just makes no sense. There's no fullscreen with borders. But a windowed can of course be maximised to fullscreen. I think that's what we talk about here.
