Deecy currently requires a GPU with Vulkan (Linux) or D3D12 (Windows) support. Dawn will revert to software rendering otherwise, with terrible performance.
Here are the steps I identified while toying with it:
- Re-compile Dawn with OpenGL and/or D3D11 support. Doable (couple of CMake toggles and very small patches for D3D11 to compile), mostly just annoying.
- Configure zgpu with
dawn_allow_unsafe_apis, and modify it to also include the disable_adapter_blocklist toggle.
- Modify zgpu to request an adapter with
compatibility feature level.
- Now the real issues: Some currently required features will probably not be supported by older hardware (First one:
BGRA8UnormStorage), this would probably require a significant rewrite of the renderer and is why I probably won't even bother with properly solving the previous steps :D
Note: D3D11 is still considered experimental by Dawn. OpenGL is also a "best effort" backend. Basically odds are not in favor of any of this working at all.
