Running the just released 3.1 beta here. I'd say my machine's specs are pretty high: Mac, 6 core i7, 32GB RAM, SSD.
When using the editor it feels laggy. When running a scene it's getting worse, up to a point where I rather quit the scene, do my edits and then restart. CPU usage is not high and the game is running at 300+ FPS, also other apps on the Mac are running just fine.
So I was wondering if there's maybe a new performance intensive feature that can maybe be the reason? Is anybody else observing similar problems?
