Pictured: My Godot 4 game running on CrazyGames. This was previously impossible because most websites don't support SharedArrayBuffers/CrossOriginIsolation, which was required to run Godot on the web.
Today is a glorious day for us webgame developers. Godot 4 is finally viable to use thanks to this PR which should be merged by 4.3
This allows you to force the exported game to run on a single thread, meaning you don't need any special headers and your game should be able to run anywhere on the internet. This has the added benefit of making the games work properly on MacOS/iOS, which for some reason had serious issues with SharedArrayBuffers causing the browser to freeze.
Brings a tear to my eye, really. I might not need Unity for my next project.
If true I may actually switch from 3.5 to 4.3. Thanks for the info good sir.
