This.. is incorrect. If I go to chrome://gpu (I'm using Chrome on Windows!) it says "WebGL2: Hardware accelerated". I have an RTX 3060. There is no reason this shouldn't work.
There's no error in the console for me to go off of, and the source code is packed/obfuscated, so I can't tell what the problem is. I can't tell if it's pre-emptively refusing to run because I'm not on a whitelist, or running into some sort of error.
