    Phoronix: Unreal Engine 5 Hits Early Access, Linux Still Supported

    Epic Games today pushed Unreal Engine 5 out to early access. Like with UE4, Unreal Engine 5 continues offering native Linux support and allowing use of the Vulkan API...

    I feel it's important to note, 2 of the biggest new features of UE5: Lumen, and Nanite, are Windows and next-gen console only. This may change as UE5 gets closer to full release, but at least for early access they don't run on Linux (at least not natively).

      What's in there that makes them OS-dependent?

        Probably Microsoft's big pockets.

          Likely Linux is missing an API to load and map files with priority in the background. The new games potentially load gigabytes every second.

            I don't know, but Windows as part of DirectX has this thing called DirectStorage which loads things directly from the SSD into the graphics card, bypassing the CPU, RAM and all that stuff.

              Simply D3D 11/12 being dominant api and Windows 10 being dominant OS. Due to this things move so slowly on anything non D3D and non Windows.

              Vulkan is only there on UE due to Android , so it is not important for them to push everything latest and great in it. Linux is even lower priority for UE so it is not really surprising, for latest and shiny stuff always Windows is way to go.

                  Could be because Linux needs things that can actually do it. Could be because its not finished yet and is prioritized. Who knows. Could be both.

                  Isn't it the motto of the open source Linux geeks to do it yourself if you want it lol.

                    No, users can't make drivers, users can't bring up rendering backends.

                    Nearly all of the huge tasks/accomplishments etc. you are seeing on Linux world has developers working on those full time and being funded/employed by companies.

                    So; no. Linux users can't bring nanite to UE5 for Vulkan.

                    So there are things that can be considered as "doable" by Linux geeks but nearly all of the big things that somehow lacks Linux support are not possible without corporate backing/full time devs with expertise.

                    Until Epic does it; there won't be nanite stuff on UE5 Vulkan.
