Help! At seemingly random times, the whole game spazzes out, all objects affected by the game's physics (including NPCs) start flying in random directions, most of the time it only happens to objects behind me (I hear them fly around, I turn around and I see them lying on the floor in a mess), but at rare occasions it happens in front of me.

When I am near rivers or the sea, the water spazzes out as well, and for a brief moment the entire world is flooded, meaning I can swim in the sky, but this usually only lasts for like one or two seconds before it reverts to normal. Somehow one time this happened I was sent flying as if hit by a giant when the water disappeared again.

Any exorcists on this board with advice as to how to fix this bizzare behavior, or know what is causing it?

Turn on V-Sync

After performing the suggested ritual, the demon seems to be dormant for now. Thank you.
