This is one of the cornerstones in why having better equipment makes you better at toribash. The faster of PC you have, the faster it can render the game and thus you can see the ghost interactions with your "opponent" without much of a delay. 2-3 years ago I set into a crusade to try a workaround, but the best I ever got were using a cheat engine showing every 5th frame of the game, at the cost of a very, I need to emphasize veeeeeeeeeeeeery, laggy experience which had me drop the project and move on to disabling ghosts and starting to play without them. I see no harm to finally geting a solution to this inherent problem with the game engine.
