Found another issue with the FreeLook. I noticed that my input was stuttering really hard at times, particularly when the values were low. So, I slowed it down by increasing the acceleration and deceleration times and noticed that the FreeLook exhibits a sort of stepping as it repeatedly speeds up and halts, despite input remaining constant.
Here’s a video showing the stepping behavior. Notice that, even though the input values don’t change, the camera orbits in steps.
By design or otherwise, this is a pretty big deal for a player camera. It’s been very distracting, even while just testing, and it’s particularly harsh with a mouse. A constant input needs to be met with a constant result.
