Can't edit any longer but just to clarify: That was on DuckDuckGo on Android, which is my one and only browser on mobile. So if something doesn't work with it, I disengage. Given this is HN, benefit of the doubt :)

Meaning now trying it on Desktop with Firefox and DuckDuckGo as an extension it works just fine.

On both, the FPS display is basically pegged at 60 FPS. So I think this is probably technologically awesome work for the performance side and just isn't compatible with some specific setup(s).

ah yeah that makes sense, i use SharedArrayBuffers which i think duckduckgo on android might not support. the project is more of a template or a place to learn than a plug and play web table at this stage, will make a fallback to running everything on the main thread for browsers that don't want to implement SharedArrayBuffer
