Handling variable frame rate in SDL2
The most consistent way to do this is to use a fixed time step for your game logic. This avoids game logic oddities due to rounding errors when frame rate changes (collisions or events that don't ...

Dynamic frame rate in Unity
I think render to texture is still your best bet. If you took a "screenshot" of what the camera sees and just display that texture the rendering cost should be cheap even at 30fps.

What's causing this stutter when framerate fluctuates?
You're averaging the total travel of the mouse on a frame.
The travel of the mouse is proportional to the speed the player is moving the mouse and the duration over which you measure the movement.
