The Vulkan API is still a small level API but it has been welcomed by gamers with arms wide open and for good reason as well. We have seen that games using the Vulkan API run better on AMD GPUs.
Although the Vulkan API will support these older operating systems, one thing to note here is that multiple GPUs will only be supported on the Windows 10 platform.
This means that if you want to play a game using the Vulkan API and want to take full advantage of Nvidia SLI or AMD CrossFire then you will need to be running Windows 10 in order to do so.
Khronos Group showed a slide at GDC 2017, which we have included here.
In this slide we can see that SLI and CrossFire will only work if WDDM it is set in the “linked display” mode, this option is only available with Windows 10 and not the previous versions of the operating system.
AMD Vega is going to be coming out later this year and it will be interesting to see what kind of performance it will have to offer and what kind of performance boost Vulkan API will have to offer.
The thing is that the Vulkan API is still very small and there aren’t many games that support the API. This is a decision that only developers can make. AMD might be looking into getting more developers on board when it comes to working on the Vulkan API but as of right now we have no confirmation regarding the matter.
It will be interesting to see what the future has in store for both AMD and Vulkan. Let us know what you think about Vulkan.
