Directx 12 vs Vulkan

What is the difference between Directx 12and Vulkan?

[Fasauceome]

DirectX is developed by Microsoft. Vulkan is derived from AMD's mantle API and is not closed source. The only real difference between the two is that I've heard them both described as "low level" APIs, able to better leverage parallel compute resources than their predecessors.

They are different APIs.

I'm not sure of what the above article is saying, as the site doesn't load for me. I'm reading on the link, it says slightly behind Vulkan. It really comes down on the application, however today I'd prefer DX12 to Vulkan. There are far better works that will be done using DX12 on Unreal Engine 5, Vulkan will be shadowed by them (it already is being).

However, one advantage of Vulkan was, higher performance. You lose some of the pretty bits that are there with DX12, while rendering in supposedly higher performance. AMD cards especially used to excel at Vulkan.

Aside from what others have mentioned, DirectX is a whole suite of APIs (Direct3D, DirectSound, DirectMusic, ...) that does much more than just 3D graphics, while Vulkan is focused on graphics.

 

Other than that, they are different APIs that can be used to achieve the same thing. DirectX is limited to Microsoft platforms (Windows, Xbox), while Vulkan is also available on other platforms (e.g. Linux)

Vulkan is going to leverage resources from a lower power card better, DX12 is going to be better with more muscle.

Anyone looking for a clear choice between these is going to be disappointed.

 

Generally speaking, both APIs are great choices for Windows.

(DX12 is Windows/XBox specific.  Vulkan is supported on more platforms - primarily Windows, Linux, Android....)

 

In 2023, Vulkan seems to have a little bit more documentation, books, and tutorials.  Although Microsoft has decent stuff for DX12.

 

Many games support both and let the user choose.

 

Especially thought it was worth mentioning that Unreal supports both Vulkan and Dx12.  You can select target RHI in project settings.  Nanite and VSM work in both.

 

AMD and Nvidia support both.

 

There are no significant differences in capabilities (which is not a big surprise as they are exposing functionality for the same hardware).  Both APIs are focused in enabling better low level control of resource allocation and management.

I'd say that DX 7, 8, 9, 11 and  12 is far less likely to have issues/crash than Vulkan; running better doesn't mean much if the API crashes the game. This is one of the reasons I despise Vulkan; for a crash free experience in RDR 2 or Ghost Recon Breakpoint; DX12 and 11, respectively, are the answer.

Playing RDR2 on my 3080, first time I have used Vulkan and after the second or third time loading up the game I would get a random black screen flickering, however the HUD would remain, sometimes it would be from the moment the game loaded sometimes it would be after a hour or so play, but it would just be a very quick black screen flicker. I tried all sorts of fixes, eventually changed from Vulkan to DX12 and boom, gone, played 8-10hours since the change and not had any other issues since with all settings kept the same and frame rate nearly identical.
