This is the first version that I would consider "production ready."
This is likely the last release before needing to use C++ for tasks like detecting if the user's GPU supports Ray Tracing, as this isn't exposed in Blueprint. Oh, and there's DLSS Ray Reconstruction now if you're interested. ;)
By default, it launches with DirectX12_SM6, but you can also launch it with DirectX12_SM5, Vulkan_SM6, Vulkan_SM5, or DirectX11_SM5. Keep in mind that almost everything is broken in SM5, but I’ve enabled it in case you need to try it anyway. Vulkan still lacks full support for Lumen HWRT in version Unreal Engine 5.4, but in 5.5, it will be on par with DirectX12.
