The closest walls of that room are being culled automatically, and I’m moving around with WASD. Sorry for the low FPS, my GIF recorder and computer are shitty.

That scene in the Editor. The red and blue lines emanating from the camera were put there to debug some quaternion math for the camera following.

Here’s switching the view with J and L. The walls are autoculled correctly. The little jog in the camera after each rotation is just an incorrect damping parameter in the camera logic and is easy to fix.
