Doing anything where mispredictions result in a few frames of doing the wrong thing escape to the user is going to make games feel really inconsistent. If the game is running at 60fps and you have a system that can predict with 99% accuracy (which seems wildly optimistic) you’re still going to have mispredictions at a pretty high rate. Not to mention that the game will have to be written especially to allow for the simulation to be rolled back and forth. For example a misprediction triggers a sword swing it turns out you didn’t make that traps the player in a state for a second. You end up giving the player a horrible experience where the game seemingly has a mind of its own. Or you can roll back and interpolate from the bad state back to a good one which would be ideal. Then the middle ground is to rollback and have a cut in the action back from misprediction. Then you realise this is happening every second or two.
