Well, I was just playing, and then I decided to disable slow-mo mode, and, instead of pressing control+o, I did control+p, and I accidentally found the debug mode, that shows the fps, if the slow-mo is active, and the time scale it is running, looks pretty useful, so I'm sharing it here

Old news. Useful anyways.
The ctrl+P is very useful when delagging the game.
(press ctrl+p and use 3 & 4 to adjust SimToRealCap around 60)

Might aswell share it here, ctrl+M shows the materials of the ground,
pressing it againg shows most of the active MO's
and one more time restores normality.
