*** Update *** an asute reader spotted some quick and dirty benchmarks over at Guru of 3D. It looks like the RX480 does indeed benefit from Vulkan, the GTX 1070 not so much.
While this does not mean that the new DOOM will run on Linux, today does see Vulkan support arriving for the new FPS. As we have seen with titles such as BF4 this is not going to benefit users of high end GPUs in any great way, however gamers on a budget should see improvements. Bethesda did not update their minimum specs but do anticipate older cards being able to maintain more respectable framerates; the current minimum specs are a GTX 670 or HD 7870. Expect to see some bugs as this their first shot at the Vulkan API, but do check it out if you have a lower end card or are simply curious how well it works. Handy links for drivers and more info over at Bethesda.
"At id Software, we’ve always pushed technology. With DOOM we let the game drive the technology decisions from early on. This has continued even in post-release, with new updates and more. Today we’re excited to share another big technology push: Vulkan support is now live on PC."

What will be the differences
What will be the differences between AMD’s async-compute in the hardware compared Nvidia’s async-compute implemented in Nvidia’s driver/middleware/software solution. I mean if AMD’s async-compute thread scheduling/dispatch are in AMD’s GPU hardware, and Nvidia has to implement their async-compute thread scheduling/dispatch using some software solution then there is no way that Nvidia’s in software solution is going to be as responsive as AMD’s fully in the GPU’s hardware solution.
Nvidia’s GPU SKUs on its prior to Pascal micro-architecture, and even with is Pascal micro-architecture, are going to have problems with some thread scheduling that is very asynchronous and random in nature. Nvidia is going to have to try very hard to hide any latency with software and driver tweaks but still with the DX12/Vulkan APIs and VR games throwing more asynchronous calls at a GPU at much faster rates than ever before there will be a limit to what can be done with software assisted asynchronous GPU processor thread scheduling/dispatching. One need only look at Intel’s SMT/”HyperThreading(TM)” CPU processor asynchronous thread scheduling/dispatching in it’s CPUs hardware to see that having all the hardware support makes for better CPU execution resources utilization and a lower latency response to dynamic workloads. The same is true for GPU processors.
So AMD’s GPU hardware ACE units are able to do the GPU thread scheduling/dispatch fully on the ACE units hardware and to help things along for AMD’s Polaris micro-architecture, AMD has added GPU instruction pre-fetch and there will be a primitive discard accelerator to more efficiently cull out any un-needed/hidden geometry in its GCN 4/Polaris based GPU SKUs. Nvidia has improved its GP100 Pascal thread scheduling/dispatching down to the instruction level, but that still requires a software(Cuda) solution and has Nvidia brought that GP100 Pascal functionality down to GP104/GP106, and still with GP100 Nvidia requires a software based solution to manage Nvidia’s “async-compute”.
The Games makers will be tweaking all their games to get at every last little bit of AMD’s async-compute using DX12/Vulkan and any explicit multi-adaptor advantage that can be obtained using the new graphics APIs. With the mobile gaming market 100% behind Vulkan expect that that’s where the development dollars will be going to get the Vulkan Graphics API as efficient as possible and taking every advantage of any GPU makers async-compute going froward. Just watch AMD Pascal GCN 4.0 And its 3.0/2.0 hardware as the games/gaming engines begin to take advantage of the Vulkan graphics API. Vulkan will also be able to accelerate via the GPU more of the non graphics gaming compute so those with weaker CPUs will see some improvement in any games that move more compute onto the GPU, as well as graphics.

Availability of the GTX 1080 is so dreadful that even NVIDIA didn’t have one. Check the video’s description.

I see about a 20 fps bump
I see about a 20 fps bump with Vulkan on a machine with an AMD APU (A10-7860K) and an AMD R9 Nano.
There’s a decent bump even for 1070 class hardware at 1440p, but at 4K, I don’t notice a difference. At 1080p, you can see the mythical 200 fps which almost nobody can realize with their display.
At 1080p, the GTX 1080 would be ludicrous (no benefit over a 1070 / 980 Ti / TITAN X class GPU.)
My Fury X is does 1080p 200
My Fury X is does 1080p 200 fps and 3440 x 1440 @ 110 FPS a very large jump
Looking at Guru3D’s
Looking at Guru3D’s benchmarks, the 16nm Maxwell(pascal) performs as the 28nm Maxwell. No significant change in performance from a low level API like Vulkan. On the other hand, AMD’s cards gain at least 20%.

Go AMD. They are looking better every day. Go Raja.
Pascal will give a limited to
Pascal will give a limited to its process shrink improvements for DX11 games, and some limited Vulkan/DX12 close to the metal improvements relative to AMD’s much larger improvements. Nvidia will have to really pull out all it’s driver and Software/Middleware stops to get some larger DX12/Vulkan improvements on it’s hardware. Nvidia will have to work it’s overclocking and middleware angle to get enough improvements to allow for more time for Nvidia to get better full hardware async-compute in line for Volta. If Nvidia is not holding back that GP100 small improvement from its GP104/GP106 micro-architectures. For all we know Nvidia may have stripped out a lot of GP100’s limited “async-compute” features to save on power usage, and is still trying to sale its smaller power usage advantage in Pascal to some not so knowledgeable customers.
There will be the VR games that will need to have a very low latency response to changing game workloads that will really show why AMD’s fully in the hardware async-compute instruction scheduling/dispatch is the only way to make VR gaming perform for the kinds of VR lowest latency possible responses via some fully in the GPU’s hardware async-compute support.
When the fully capable Vulkan, and DX12, benchmarks are online and are able to stress test a GPUs hardware with test code specifically designed to get at any of a GPU’s hardware asynchronous instruction dispatch/scheduling abilities and can measure the difference between a GPU with these features implemented in hardware and a GPU that does not have the features fully implemented in hardware but instead have the features emulated in software. Then there will be a marked difference that can not be seen seen in most games that are using the old APIs.
There will be some DX12/Vulkan synthetic benchmarks that will be able to stress test a GPUs in hardware scheduling/dispatch abilities while also being able to measure closely any losses from having emulate in software any functionality not in the GPUs hardware. These synthetic benchmarks will be good for some measurements until the games/gaming engine software all have had time to be fully optimized for DX12/Vulkan. So until the games software fully catches up in a year or two there will be some synthetic DX12/Vulkan benchmarks to use until the majority of games catch up/are optimized and are truly able to show the hardware based async-compute advantage.
Nvidia was going to offer
Nvidia was going to offer simple software emulation to Maxwell cards with newest drivers. We all remember their promises. Instead they decided to market that “feature” under the name dynamic load balancing with Pascal.
The first indications from tests with Doom and Tomb Raider, point to be nothing more than a marketing name to cover up the lack of hardware, something maybe necessary to make it easier for buyers to swallow those Pascal prices.
Doom (1070 results)

Tomb Raider (980Ti results)

And they are going to have to
And they are going to have to offer software emulation for Pascal, because Nvidia does not have async-compute fully in Pascal’s hardware also. And the Pascal consumer SKUs GP104/GP106 may not even have what little async-compute improvements that P100 has, if Nvidia did not include the hardware that GP100 has in its GP104/GP106 consumer SKUs. Nvidia is a big product segmentator like Intel, just look at GP106 and SLI. Nvidia is about the milking of every little bit of GPU capability for every little extra dollar.
Nvidia is going to have to overclock and GameWorks(TM) it’s way to some form of attempted parity to AMD’s async-compute, until Nvidia can fix that async-compute deficiency. AMD’s products, even AMD’s older GPU SKUs, are going to show more improvement as DX12/Vulkan become more adopted. Vega should have even more to offer inside its ACE units, so those CPU like feature sets are going to offer more from AMD’s ACE equipped hardware. Polaris has 2 hardware scheduler units, so who Knows what Vega will have. Polaris will not have to do any computing of unnecessary/hidden mesh geometry, while also being able to do GPU instruction pre-fetch and maybe even a little speculative execution in the ACE units.
That dynamic load balancing with Pascal appears to be for GP100 and is supported only in CUDA(TM) code.

Remember that Vulkan is what
Remember that Vulkan is what you get when the Mantle comes to the surface. So all that Mantle work has gone into Vulkan and Vulkan is the public face of AMD’s Mantle project and more! Vulkan will be supported across all the devices markets and not only on just PCs/Laptops. So the Vulkan API will get the needed support from all the developers. Those gaming tweaks to Vulkan for the mobile devices market will transfer to the PC/laptop market and the other way around for all the billions of Vulkan API enabled devices. I can not wait to see what sort of RX480/AMD CPU affordable Steam Machines will be coming online over the next months once the AM4 motherboards are ready and there can be some Bristol Ridge based SKUs that will be able to be updated to Zen when Zen becomes widely available.

It looks like this will go down like a cup of cold sick at NV hq .. just in time for the 1060 reviews. I’m sure they thought this game was in the bag too.
This sort of Flip flopping is not good for NV , the more engines / games that get ported to modern APIs , they are tending to loose advantage – outright loss.
I say this owning Maxwell Titan X , sick of seeing no benefits from Modern APIs.
Really looking forward to the Doom vulkan battle between 1060 and RX480.

AMD OGL drivers have been garbage for as long as I can remember.
Often times a GTX 970 performs as well as a Fury X in the same game.
That’s not to say that Nvidia OGL drivers have been good either but AMDs OGL drivers specifically have been so bad that almost always linux gamers have no option but Nvidia.

If I heard it correctly, in the demo or the beta or whatever it was, the game ran OpenGL 4.5 on both AMD and Nvidia cards, but when the game released, it stuck AMD cards on OpenGL 4.2.
It’s hardware related to what
It’s hardware related to what your AMD card will support. An r9 300 series has 4.5 support. Always assuming gimping to make Nvidia look better. In fact I would believe the opposite. AMD would probably gimp it themselves by using lower version to make gains from Vulkan look that much more impressive. Just my opinion though. Or wait does second link shed some light on this.

Or it was actually an AMD driver issue they fixed a few days after release. LOL fanboys.

Fury X faster than 1070 on Vulkan?! WOW! Yes please!
As the fury non x and x
As the fury non x and x versions are still more expensive $500+ than a 1070 retail price. Fury products aren’t widely available. If you’re a red fan you’re better off waiting for Vega than buying Fury.
I don’t view this as much of a problem for Nvidia. There is still an opengl version that they oWhat did enthusiast 1080 compared to your enthusiast Furyx do. Right, some lame excuse Nvidia didn’t even have one. Right. I believe that one. Also side note Bethesda is working with Nvidia to get their version of async working with Vulkan.
Does Vulkan do anything for the horrible frame times of AMD cards or does it still look like seismographs of 4.0+ earthquakes? This is more important than getting a few more frames than Nvidia. Nvidia’s VR under steam VR is silky smooth compared to AMD.
On top of the performance
On top of the performance gains being seen on AMD cards there is also a very nice power savings. Seems like AMD has to work a lot harder running DX11/Open GL.

What about this article? Says Doom was running at 50-55 fps on 1080 but with Vulkan well over 120fps up to 200 fps. Shows over 100% gain. May have been a trick with vsync on or using 60hz monitor to artificially lower 1080 performance on opengl. Don’t know for sure though. All marketing things tend to misrepresent in one way or another to show things in the best light.
http://www.kotaku.com.au/2016/05/doom-will-support-vulkan-with-extra-performance-gains/
Using 980ti got 60 fps boost. Something is smelly maybe they were using older drivers for Nvidia that aren’t Vulkan compatible to make AMD look better.

It seems that somehow asynchronous compute is not running on Doom Vulcan on Nvidia but was running before in beta?
https://community.bethesda.net/thread/54585?start=0&tstart=0
Here is relevant text
Does DOOM support asynchronous compute when running on the Vulkan API?
Asynchronous compute is a feature that provides additional performance gains on top of the baseline id Tech 6 Vulkan feature set.
Currently asynchronous compute is only supported on AMD GPUs and requires DOOM Vulkan supported drivers to run. We are working with NVIDIA to enable asynchronous compute in Vulkan on NVIDIA GPUs. We hope to have an update soon.
