So, wait

When Vulkan submits work to the GPU, it can schedule a fence to be signaled when the work is complete, and…

The CPU can:

• ask if the fence is signaled right now (without blocking)
• synchronously block the calling thread until the fence becomes signaled

But there’s no way to hook it up to an event loop?!?! Like, there is a way to turn the fence into a file descriptor, but passing that file descriptor to select() or epoll() does nothing?

What a joke API

• Experimental support for subgroup is added behind a flag, please test it and provide feedback!
• Rendering to slices of 3D textures is now posible.

WebGPU in Chrome 124 gets two very requested features:

• read-write storage textures for more compute flexibility (previously write-only was the only mode allowed),
• support for using WebGPU from additional types of JS worker!

Is there a legitimate reason why anyone would want to run WebGL on a server? (As opposed to running WebGL on the client, or running OpenGL (or something else) on the server)?

People keep asking me about this over the years, and each time they do, I’m always bewildered why anyone would want to do that.

I guess if you want to avoid writing security-conscious code, then you could instead delegate all security mitigations to the WebGL layer, instead of just writing safe code in the first place 🤔

Chrome 121 supports WebGPU on Android (mostly thanks to @tojiro and a bunch of other niceties like being able to omit the entryPoint name when creating pipelines.

Next release seems fairly quiet but Chrome 123 looks like it will have a lot more new features!

Here are the release notes for #WebGPU in Chromium 119: https://developer.chrome.com/blog/new-in-webgpu-119/

Filterable 32-bit float textures, unorm10-10-10-2 vertex format, and rgb10a2uint texture format and more! We have a much awaited extension that starts with an f and ends with a 16 in the next release :)

Here are the release notes for #WebGPU in Chromium 117: https://developer.chrome.com/en/blog/new-in-webgpu-117/

Standing out among the small features and fixes are a fix for the caching of pipeline with implicit layouts so that pages using them should now start much quicker! (after the first load)

Here are the release notes for WebGPU in Chromium 116: https://developer.chrome.com/blog/new-in-webgpu-116/

WebGPU now integrates will with WebCodecs for super efficient video processing! Of course there are tons of tiny improvements in ergonomics, perf and more in the 100s of new commits :)
