Try this page on desktop safari vs desktop chrome:

It is insanely slow pointerlock tracking on safari. Once we grab the pointer, you need to move the mouse almost a meter across the desk to rotate 180’. It’s super fast and responsive in chrome.

I’m using babylon 3.3 and BABYLON.UniversalCamera. Is there some trick here that I’m missing?

Increasing the sensitivity doesn’t seem to help because the rotation speed seems to be tied to the render time. Even if we’re still hitting 60fps, the time spent in `scene.render()` seems to control how responsive the mouse tracking is.

Scratching my head on this one.

I have no mac but you can try to increase `mouse.angularSensibility` to control the rotation speed
