Moved the autosave off the main thread. Reports indicate this has vastly improved performance for those affected.
Added an option for players to toggle autosave off. In the event you continue to experience stuttering, please disable this in the Options menu. When finishing a session, please be sure to quit the game from the menu to ensure progress is saved. (For example don’t alt+tab to close the program or the autosave will not work and you will lose your wash progress on that level).
Legacy wash mode improvements to bring the effectiveness more in line with Standard.
