Description

I know we can limit how often the Rewind feature takes a snapshot and if it would be set at for example every frame than that would be how fast we would rewind.

I think Rewind needs a delay setting that freezes a rewound frame for X milliseconds. That way we could rewind slower without having to force a snapshot every single frame.

So instead of Rewind rewinding as fast as possible - 1 snapshot per frame - it would rewind 1 snapshot, wait 100 milliseconds while the Rewind key is held and then rewind another snapshot and so on.

It would make Rewind much more useful and resource friendly.

Research direction

The issue names no file, test, or entry point. Start by locating the Rewind implementation and the loop used while the Rewind key is held, then trace how snapshot frequency is configured. Done means a delay setting causes rewind to pause between snapshots while preserving the requested resource-friendly behavior.
