Why is linux supporting taking a while? I figured the underlying graphics subsystem on Android is Vulcan right? Wouldn't that also be the main graphics subsystem on Linux these days?

Testing/Validation and bugfixing. Just having Vulkan isn't enough to enable it by default, everything actually has to work right. Even for Android this is only for specific types of devices. You should be able to force enable it on Linux right now though. It's just not GA quality guaranteed.

I tried and tried and tried, Chrome 120 will always stick an undocumented Origin Trial for disabling WebGPU.

You know we’ll have all moved onto Romulan by then, leaving Vulkan and Metal behind - including WebGPU.

In seriousness though, WebGPU in Chrome with “non-free” Linux GPU drivers should work, no?

Edit: I see it’s still behind a flag

about:flags in Chromium

search for "accel"

Disable the blacklist for your GPU.

Which is exactly why WebGL never really took off for games like Flash did, versus native games, or now streaming.

Having drivers installed is not enough as the browser lords decided the computer isn't worthy of playing games.

Flash was a buggy crap which made lots of older computers spawn cycles like crazy and had zero accesibility for the blind. It deserverd to die.

Usually the only ones complaining are Linux users.

The rest enjoyed the games, to the point that Flash is being brought back thanks WebAssembly, with Unity and Flutter as spiritual sucessors.

Doesn't stop disablement done through --origin-trial-disable-feature=WebGPU and I have yet to figure how to drop that without recompiling Chrome.

Afaik it is possible only in unstable and beta, not in stable. That's why GP mentioned Chromium, not Chrome.

Which fully supports pjmlp's point in the sibling comment.

On ChromeOS.

On devices by selected vendors, and only on selected models.
