I think many people don't know that there is actually a difference between auto reprojection and forced on reprojection, the first one almost always creates ghosting artifacts all around the cockpit, the second one creates artifacts only around overlapping edges (see video attached, 45fps reprojection through the lense).
If you run reprojection, it's important to leave some headroom for the GPU (6-7ms of frametimes), otherwise it will ghost.
