What is Vulkan? What is the difference between Vulkan and DX11

Vulkan presents a potential performance increase over DX11 in most cases, though may be slightly less stable for now. We generally recommend you use Vulkan, the default Graphics API.

The Vulkan implementation of Baldur’s Gate 3 is still in Early Access. We are actively working on performance improvements and stability. We want to collect as much feedback as possible, but it should not be used to measure overall performance at this stage. If you are having performance issues, please try the DX11 API instead, which is available through the launcher.
