Interesting.
Did you play WebGL version? Web version can be pretty laggy.
Also spawning hundreds of cubes almost all with physics can be pretty taxing on CPU. So I can totally see it lagging. My i7-12700h handled both WebGL(at 60fps) and Windows (at 165fps) without any hiccups. I’m curious what CPU you are using? Asking so I won’t overwhelm any CPUs next time I build a game.
Thanks for your feedback, it is much appreciated 🙂❤️
