After I made the change, the game crashes on launch. I already removed old drivers with DDU, and installed the most recent version My question is: is there anybody who can start and run DOOM demo with latest driver? I read somewhere that this error may depend on VulkanRT library. Currently, on my system I have 1.

And no, switching back to OpenGL is not a solution. It should be 1, or not? Showing 1 - 14 of 14 comments.

At the time, we were promised that a patch with support for the Vulkan API would show up "soon after launch," which apparently meant around two months. The good news is that after all this waiting, the public Vulkan patch went live last week ; there's also a FAQ on Doom's Vulkan support that has additional information. So what is Vulkan and why should anyone care?

The key element we want to discuss is what it means to be 'low-level' and how that changes the game engine. This gets technical, but it will help set the stage for what we see in the benchmarks.

Doom benchmarks return: Vulkan vs. OpenGL

Software developers typically use programming libraries to help make their jobs easier. Imagine you want to create a game for Windows; there's a lot of work involved in doing so, but many common tasks can be handled by a programming library—an API, or Application Programming Interface. Rather than reinventing the wheel for each new program, tasks like graphics, audio, window resizing and positioning, reading and writing to storage, and more can simply use an existing library to make life easier.

Focusing specifically on the realm of graphics, the API helps handle things like texturing, lighting, and creating all the amazing visuals we see in modern games. But using a library also involves some level of abstraction, and in the world of graphics it means you have a driver that supports the set of functions in the library, and it maps those to the actual hardware. In the past decade or two, most graphics APIs have been 'high-level,' meaning there's a larger amount of abstraction.

This generally makes the job of the programmers easier, at the cost of some performance optimizations. Some developers have wanted ways to extract more performance from the hardware, however, and they've basically asked for 'low-level' access to the hardware.

That means more work in some cases, but it can also improve performance if you know what you're doing. And that brings us to Vulkan and DirectX Ultimately, the end goal is the same: allow developers to extract more performance from the hardware if they want to put in the effort.

There's some politics involved with the low-level API discussion as well. The biggest item is that AMD supports a feature called asynchronous compute, which is basically the ability to mix and match graphics and compute instructions in the execution units.

Fundamentally, AMD and Nvidia architectures aren't the same, and this is why we run benchmarks. That makes the Fury X percent faster. I picked the Fury X and GTX Ti for a good reason: on paper the Fury X should be substantially faster, but in practice the Ti ends up with a small lead of around five percent the Fury X does lead by five percent at 4K, however. With a low-level API, AMD's ACE has the potential to help better utilize certain resources, particularly if the developers spend some effort to better optimize their code.

Instead of utilizing percent of the available execution units, they might be able to get to percent utilization, and that could make a big difference when it comes to the end user's experience. Now combine the above discussion with AMD's presence in all the current generation of consoles, and AMD has a vested interest in finding ways to improve the performance of their hardware.

This is arguably why they created Mantle, and why they're so interested in DirectX But couldn't AMD accomplish something similar by simply spending a lot of resources to optimize their DirectX 11 drivers?

What about Nvidia—don't they have features and hardware elements that are handicapped by high-level APIs? Probably, though Nvidia for their part has been more interested in creating other gaming libraries rather than specifically focusing on low-level APIs. With all of the above out of the way, let's talk expectations.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Gabe Newell is quoted as being strongly in favour, without further explanation. What exactly is Vulkan's relationship to OpenGL? Update: The Vulkan 1. Originally referred to "glNext," one can infer that Vulkan was likely going to end up being "OpenGL 5," but that the standards body eventually decided that a new name would better coincide with the relatively clean break the API purports to make from existing OpenGL paradigms.

Vulkan's practical advantages to game developers are primarily about control as in, allowing more of it, potentially allowing for better optimizations at the cost of significantly more up-front work on the developer's part. It is, however, better typed in that not everything is a bare int ; there are relevant typedefs and so on.

It is much lower-level than OpenGL. OpenGL might achieve comparable performance to Vulkan, in draw calls per second, but also regarding general driver overhead:.

Anko Anko Leonard Nimoythe actor of Spock a very popular character recently died onso speculation abounds that the name was a tribute. However, it was coincidental: The Vulkan trademark request was filed on ; before Nimoy's death. Active Oldest Votes. Specifically: The API is oriented around asynchronous generation of command buffers across multiple threads and sequenced processing of those buffers to a command pipeline.

This reflects the realities of modern hardware. Thread and memory management tasks are left to the application, not the driver, allowing game developers more control over those behaviors and thus potentially more accurate tailoring of those behaviors to their individual game's needs. Validation and diagnostics layers can be independently enabled, allowing in theory for better tools integration with the API something OpenGL itself has suffered from and disabling of excessive validation, in theory allowing " the graphics on level three " to be that much more performant.

There's no hard API differential between mobile and desktop versions, which will in theory ease the porting of cross-platform games and if nothing else reduce version-checking headaches that everybody hates.

Extremely short version: Games that run on Vulkan API are supposedly more efficient and optimized than those without. It gets you more bang for your buck when it comes to rendering graphics and such.

Anyone who wants to elaborate or correct my overly simplistic explanation be my guest, because that is about all I know about it so far, I have no direct experience with it. Vulkan with a 'k' is a low level API application program interface. You should not need to download anything out of the ordinary; both AMD and Nvidia's recent driver packages contain everything you need to use Vulkan and the patch containing Vulkan will automatically download and update DOOM when it is available.

But how does this translate into the real world?

Doom OpenGL VS Vulkan Graphics Performance Analysis

That being said, most games run in OpenGL ES 2,0, and there is a huge difference here, which you can see above. This is where Vulkan comes in, offering at least the same in graphics quality, but with improved performance. So how does Vulkan do? There are a few reasons to why this is.

The multithreading capabilities are a lot better with Vulkan, allowing for all 8 cores to get a workout, not just one. The CPU usage reported in task manager is more than likely a bit misleading.

I believe this is the case because Vulkan spreads out the load of this example across all 8 cores, instead of just one with OpenGL ES 3. So while it is technically using more of my CPU, the CPU is not as stressed as the work is spread out between the cores. Notice that the RAM usage does not change between tests as well. Usually, you want this number to be lower, as performance can suffer, but in this case, the new API stomps all over ES 3.

OpenGL ES 3. While this is essentially nothing to my desktop, on a phone this could be a huge difference and we could see percent GPU difference possibly.

Imagination has also observed similar results in their tests. This test really shows how well the new API works with multiple threads and how much it benefits from doing this. This is an interesting question, as at the time of writing, there are only a few devices that are actually able to utilize Vulkan. While new flagship devices running Android 7. Or not at all, like Unity. All of this will come with time, of course, but I would not hold my breath, as there are a few stars that need to be aligned before your device supports the new API.

For reference, Vulkan will be supported on Snapdragon 8xx and up with Adreno 4xx GPUs and up and Exynosand and presumably everything proceeding those models. Once Vulkan is used correctly, games will see a massive jump in quality with very little to no penalties as the API and hardware advances over the years. This is definitely an exciting time to be a developer and gamer. Vulkan looks very promising for not just Android, but also for the desktop.

The real question is how fast will developers start implementing the new API in their games. As engines progress and development gets easier, I see no reason why not to. Android Development News.
