Vulkan raytracing is being ported to AMD's Vega, Polaris, and Navi graphics cards by Joshua Ashton, known as the developer behind the DirectX to Vulkan translation layer (DXVK), which allows running 3D applications on Linux using Wine.

In a blog post penned just yesterday, Ashton explained that there is no reason for Vulkan raytracing to be limited to Big Navi (AMD's Radeon RX 6000 graphics cards), even though this doesn't guarantee that the performance will be acceptable on older hardware.
