After reloading the save attached I had bad fps, but I don't know why. (I hope I gave the right save files.)
In the video the fps counter value jumps up and down.
Since I made a recording in 60 Hz of my 144 Hz display the effect is barely visible. (On my end the effect is highly visible. Giving a heavy stuttering when moving the camera with arrowkeys or screen edge.)
