Linux builds run on Vulkan RHI instead of DirectX, while Epic Games is continuously adding support for Vulkan RHI on Linux some issues still persist, below is a list of currently know issues in 5.3
Unreal Engine Linux Support was massively updated in 5.4 and fixed a lot of issues with raytracing, physics and Vulkan RHI. If your projects allow it, update it to 5.4+
Hardware Raytracing is not supported. (Should work from 5.4+ onwards)
DLSS is not supported. (Should work from 5.4+ onwards)
SM6 features are not supported. Unreal Engine version 5.3 and above can activate SM6 for Linux.
Panning textures are not supported.
Virtual shadow maps can occasionally have visual issues.
Nanite double-sided foliage renders incorrectly.
Nanite meshes with display incorrectly in version 5.3 and above if SM6 is not enabled.
Meta Humans will crash the application at run-time. (Should work from 5.4+ onwards)
Some plugins don't work with Linux compile.
You can test previewing your project with Vulkan RHI. Just go to Project Settings, type RHI in the search bar and change the Windows Target RHI for Vulkan.
