it might seem a bit slower since you're getting double the framerate but this will work a bit to your advantage with manipulating your tori cause the mouse is more fluent
no, FPS is a scalar value of smoothness, it could show you 1 frame every second, or split the same movement over that second into 30 frames, or even further into 60?
(note the human eye sees at about 25fps)
seeing higher fps actually increases the smoothness of what you're looking at even if the human eye can only see 25 fps. in relation to alot of video games most aren't rendered at 25 or even 30 fps. rather 60 fps is the standard rendering motion so even if you see 25 fps on the 60 fps renderings if they're going 30 fps the animations still look choppy and slow. the more frames the more motion can be applied. in the case of toribash however 30 fps seems faster because the animations are rendered in 30 fps normally. doubling the fps however doesn't seem to scale the motion in toribash as much as it should giving the effect of it being slower however smoother it may be
It's largely because the physics & animation are all seperate from the rendering engine, so the objects move reguardless of whatever the frame rate might be, and it just updates the frame whenever the rendering engine says so.
