Metal 4 support roadmap?

[songhuaixu]

Just wondering if there are any plans to support Metal 4 (WWDC25) in wgpu? Specifically interested in MetalFX frame interpolation and the unified compute encoder.

If it's already being worked on, what's the rough timeline? If not, is this something the team would be open to contributions for?

Thanks!

@songhuaixu Wgpu will already work fine on Metal 4. Many of the new features don't really apply to wgpu however, since we have our own command encoding API that is separate from however the APIs decide to implement stuff like compute encoders.

MetalFX frame interpolation can be added externally but it is unlikely that wgpu will support it directly. You can look at the as_hal methods to see how this might be done.

If you have a specific feature you want you can file an issue for it. If there is support for adding it you can file a PR to contribute it yourself!
