Godot is one of the most popular open source game engines, and it's currently using GL only. It would be great to have a tighter collaboration between our teams, and I could see the following paths:
- Provide them with our Vulkan portability implementation. This can be started right now, with our task to assist the porting efforts, quickly identify and fix upcoming issues.
- Rewrite the rendering component (following the visual server protocol, as far as I see) in Rust. It's supposed to run on a separate thread(s), and we can then call gfx-hal directly from it.

Fairly succinct description of Godot's tentative plan for gfx-rs here.
_by @akien-mga_
[DirectX 9] Won't happen for several reasons:
Godot is cross-platform at its core, and won't bother supporting a proprietary API for a single platform if there are open source alternatives (OpenGL, Vulkan)
If you don't have OpenGL drivers installed, you likely also don't have DirectX installed either, so that's not a solution. What you're experiencing is probably people who don't have drivers for OpenGL 3.3 (required by Godot 3.0), and those likely wouldn't have drivers for DirectX 10+ either. This will be solved with Godot 3.1 which supports OpenGL 2.1 again, which 99.9% of the market should support.
Our way forward is to implement a Vulkan backend which is cross-platform and performant, and not spend time on a 15 year old DirectX 9 which cannot support any of Godot's rendering features.
Eventually, the Vulkan backend could be used together with a portability layer like gfx-rs which would allow to translate to DirectX 10+, Metal and OpenGL if need be - though even then I doubt DirectX 10+ support will be really useful when all hardware capable for DX10 should also support Vulkan.

IIRC @karroffel works in this direction.

Yes I am working on a rendering engine with C/C++ API, it can already present to the Godot-created window and right now I'm in the process of implementing a render graph implementation. I'll post updates later on!

@karroffel Thank you for your work on this! What's the current status of the project?

@vultix unfortunately I am no longer working on that project.
