Quoting: aFoxNamedMorrisOn a GTX 980 over here, I got capped at 120, with the occasional drop to 119.

Are you using the "+fps_max 0" argument?

Quoting: liamdaweI wouldn't just use the ones the Valve dev pointed out, there aren't any that are the "best".

No, not the "best" indeed, they are just meant to illustrate scenarios where Vulkan is efficient.
Ideally I would use more demos with specific scenarios or a single one but much longer.
For the moment though is too early (I think) to spend so much time for a benchmark that tomorrow might be obsolete.

Quoting: NyamiouThe resuls by dubigrasu already show that you can greatly change the results by using another demo

Yeah, but which one is the good one ? :)
Personally I used what dang_valve told me to use (after all, he's the damn Source Vulkan dev) for relevant Vulkan benchmarks, but I ran other demos too before that and the results were very different.
So not sure what to believe.

Quoting: liamdaweThose are just what he happened to be testing with, doesn't mean the are the best. Just different.

Ah well (I misread your post), when Phoronix tested "some" random gameplay DanG said that they were not giving a full image of what Vulkan can do, so that's why he provided the ones I used.
From what I understood they are actually the best for this task, as in putting Vulkan to work.

Quoting: Mountain ManBetween this and the OpenBenchmarking test, I'm beginning to the think the kid in this video screwed up his Linux benchmark.

Well, I don't know. Like I said, you get different results depending on what demo you use. Maybe I should've use the same demo he used for a strict/correct comparison?
But basically Valve's Dota dev said that those two demos (from Phoronix) are the ones to use when testing Vulkan...so I used one.

Well yes, you're bound to get different results depending on what demo you use.
Even those from Dan give different results although they are both meant to prove Vulkan performance. The one that I used is the most spectacular (on my configuration) in performance gain (GL vs VK).

Quoting: liamdaweSo you're using a different demo file to me then, I am using the same one the guy who did the video provided which is why I imagine my results are so different. The one in the video is much heavier.

Yeah, I'm using some demos provided by the Valve team/guy. I asked on Phoronix about some demos that he (Dan I think?) considers relevant for Vulkan and these are what he posted.

There are two file demos included:"1971360796.dem" & "OctPerf.dem". I use the first one.

I'll add some details in a moment but this is what I get on SteamOS:


SteamOS Alchemist (kernel Linux steamos 3.10-5-amd64)
Windows 10 Pro
i7-4790K
16 GB RAM
Nvidia GTX 780 with
Linux Nvidia driver 367.27
Windows Nvidia driver 368.39

Demos were ran for 10 times each for both systems.
SteamOS BPM stands for the default SteamOS configuration with steamcompmgr, the others test were made in desktop mode (Gnome 3).

For the benchmark I used a different demo than the one mentioned in this article, more exactly because dang_valve mentioned that:
The more particles/models/etc. that are on-screen during the timedemo the better I expect Vulkan to do since that is when we tend to be come renderthread CPU bound on the other APIs (GL/DX9/DX11)
and recommended these two demos on Phoronix:

The one I used is "from the Global eSports Cup Finals"

Well, shitty/evil DS/Techland or not I'm not gonna burn any bridge for now.
I still have three awesome games from them, so not ready for the hate.
Just my opinion.
