it slows down… whyyyyyyyyyy this this a default feature???
I’m not sure exactly what your problem is, screenshots or a more in-depth description would be helpful
Maybe you have
View Lock enabled?
Or your scene camera is active? If you have a numbpad, try NUMBPAD 0 or select this:
There is an invisible pivot point that your camera will rotate around and zoom to. Sometimes it gets in a weird place, especially if you pan a lot.
Go to top view, or some other view where you can see what is going on, select the object you want to zoom in on, and then press numpad . (period key)
