My player pawn hovers above the ground via a constant physics force. Additionally that player pawn also moves (via WASD keys) by applying forces on the X/Z axes as well. The main camera is attached to the player pawn via a camera boom component (which has a small camera lag set).
The problem now is that when I fly around with the player pawn from time to time the camera stutters a bit. It’s not too bad, but noticable. It doesn’t happen all the time, but every few seconds. The frame rate however constantly stays at 60 FPS in any case, even during the stutter.
I have tried to enable physics sub-stepping via project settings. It feels a bit better now, but the problem still occurs.
Now I am not 100% sure that the physics forces applied to the player pawn really cause the troubles, but unfortunately I cannot identify any other reason, in particular since the frame rate stays so constant.
Do you guys have any ideas how I could identify the reason for this issue?
