Yeah, it's part of the problem, but that would normally only give you ~60 - 100 ms lag (at least if you're on a decent connection, close-ish to the server). But we're experiencing another bug where WebTransport doesn't get a chance to send/receive data when the framerate is < 60fps (because the thread is starved), which makes it much worse than that. We're aware of it and working on it. This is the core issue: https://github.com/w3c/webtransport/issues/543

Yes, I'm quite sure this works this way. I was looking into a few implementations and the specs: https://datatracker.ietf.org/doc/html/draft-ietf-webtrans-ov... https://www.w3.org/TR/webtransport/ https://github.com/w3c/webtransport https://github.com/w3c/webtransport/blob/main/explainer.md https://github.com/aiortc/aioquic/blob/main/examples/http3_s... WebTransport just landed in Firefox release versions and is available since some time in Chromium so it's indeed ready for hacking! :-D
