Ability to customize the FPS limit or to remove it entirely

I have a 144hz monitor, and I'd like to get more than 60 FPS

The physics are calculated 60 times per second, so you won't have any gameplay benefit from that.
i'm not even sure if the smoothness of motion increases since, i guess, the position of camera and marble isn't updated faster

Could the position of the marble and camera be interpolated at high framerates? Lots of games/game engines have framerates uncoupled from their physics simulation.
