Significant improvements have been made to the graphics backend, in order to increase performance and stability of editors and runtime players targeting DirectX12. Changes include a new memory manager allowing over-commission of GPU memory (in a similar fashion to DX11) as well as a large collection of optimizations and bug fixes to improve stability and generally reduce rendering setup overhead.
In order to best utilize DX12’s multi-threaded rendering capabilities, we recommend enabling Native Graphics Jobs for runtime players.

The DirectX12 backend also utilizes DXR for enabling the Raytracing API, as well as HDRP's Raytracing effects.
