What is Vulkan in Rainbow Six Siege?

Existing players are accustomed to the DirectX 11 API, previously solely used by Rainbow Six Siege since 2015. The advantages of Vulkan often result in far less intensive rendering, primarily lowering CPU and GPU usage, and squeezing improved performance from the same hardware. In short, Vulkan cleans up how Rainbow Six Siege runs on your PC, generally improving framerates across the board.

Ubisoft introduces Vulkan after brief test server trials, leveraging findings to reduce crashes and performance issues. Public availability allows the developer to source feedback across a wider variety of hardware, improving the gains of using the API over time.

And while initial reports indicate performance bumps for many, Ubisoft warns of potential hiccups in the early days. "Please keep in mind that as we are still in the process of tweaking and testing Vulkan for Rainbow Six Siege, some players may see no change or potentially decreased performance with the initial live release," Ubisoft states. However, if among those impacted by Vulkan issues, reverting to DirectX 11 will provide a more stable backbone for gameplay.
