|User Control For Orbiting a Camera around a Target|
I prefer no acceleration or weight on the camera rotation based on player input, but that is something that many designers disagree with me about. My reasoning is that I like the immediacy of control to camera direction and I care more about accuracy than soft movement. The opposing reasoning is that it feels jumpy and unpolished. Spend some time on the smoothing parameters to get a decent compromise, especially if the smoothing also applies to cameras used for precision aiming.
