Godot now supports Vulkan foveated rendering on Android, Application SpaceWarp, DirectX 12, and OpenXR render models, and can build a universal OpenXR APK.
If you’re unaware, Godot is a free and open-source alternative to Unity and Unreal Engine. It’s technically controlled by the non-profit Godot Foundation, but all development takes place in the open.
Since last year, Meta has been funding a group of Godot veterans to improve the engine’s support for OpenXR and Quest feature extensions, as well as to build high-quality samples and documentation.
Godot can do arm yeah but there will be a slight hiccup in that godot xr opengl requires the multiview extensions that mesa (amdgpu, freedreno) does not currently support. So only vulkan projects will work as of right now. https://gitlab.freedesktop.org/mesa/mesa/-/issues/10712
Getting a godot steam frame export working should be reasonably straightforward otherwise as it is all just openxr. As it stands though with waydroid you can literally take any android openxr apk that doesn’t use meta specific extensions and it will just run out of the box on frame.
Zink merged support for it a couple months ago:
MESA_LOADER_DRIVER_OVERRIDE=zink. But yea godot’smobileVulkan renderer will likely be a better choice.
