Quake in the browser via javascript was done 5 years ago using GWT. I recall seeing that port at Google I/O years ago.

You linked to quake2-gwt-port, which is a Quake 2 port. But this is a Quake 1 JavaScript port called SiPlus' WebQuake.

I wonder how a JavaScript port done manually like this would compare to an emscripten port in terms of performance? It was a little choppy on my old laptop that can run Quake 3 decently.

I am pretty sure that this one was written from scratch, not "compiled to JavaScript".
