Vulkan API has been introduced to the Rainbow Six Siege by ubisoft, which can deliver sizeable performance benefits with your existing PC setup. This short article will guide you on what the R6 Vulkan API is and how to use Rainbow Six Siege with Vulkan API on PC.

 
 

What is Vulkan API?
Vulkan is a graphics API, which acts as the middleman between the game and your graphics card. Ubisoft is pursuing Vulkan because of its superior performance over the game’s current API, DirectX 11. Under most hardware setups, Siege should run a bit smoother with Vulkan. That’s cool and all, but Siege’s Vulkan version comes with a feature that you should definitely know about: dynamic render scaling. It’s a new setting exclusive to the Vulkan version that lets players set a target fps to constantly reach for by dynamically scaling the render resolution. You’ll find the new slider under the Graphics menu, but you have to have your anti-aliasing set to any of the available T-AA settings for it to work.
 
“The Vulkan API provides advantages over DirectX 11 that can help Rainbow Six Siege improve graphical performance,” writes the Ubisoft dev team in a new blog post. “Moreover, Vulkan as a newer API has benefits that will help to reduce CPU and GPU cost, as well as support for more modern features that can open the door to more new and exciting things in the future.”
 
How to use Vulkan API?
Utilizing Rainbow Six Siege's new Vulkan support can deliver sizeable performance benefits with your existing PC setup. Ubisoft has released Patch 4.3 for Tom Clancy's Rainbow Six Siege, also marking the arrival of Vulkan API support. Introducing the multiplayer shooter's secondary graphics API for PC players, it promises unmatched rendering optimization, targeting performance enhancements across all types of PC hardware. And while Rainbow Six Siege disables Vulkan by default, that quick switch could boost framerates title-wide.
 
This goes for both Uplay and Steam versions of the game: you need to go to your library and select Play. Assuming you are using the correct launcher (it will be the one your Rainbow Six Siege license was purchased through), an option should appear asking you to choose which version of Siege you wish to launch. The first option is the good ole’ fashioned DirectX 11 Siege, and Vulkan is what it says on the tin.
 
If you use your desktop icon to launch the game you will need to pin a new one for the Vulkan client. Currently there isn’t a way to change APIs within Rainbow Six Siege, so if you click the icon and get straight into the game chances are you are running the DX11 client. If you are not sure there is an easy way to check: pop into the graphics settings and see if Adaptive Render Scaling is an option. If so then congrats: you are in the Vulkan client.
 
When using Rainbow Six Siege with Vulkan, expect improvements to gameplay performance, allowing for higher framerates. That is the guide for how to use Vulkan with Rainbow Six Siege, if you need to buy cheap R6 Credits, we 5mmo.com is also here for help. Finally, hope you can truly enjoy the game!
