Super Mario World: All-Star Edition: Team Fangame Project

Previous, the numbers on the bottom right of the screen is FPS (frames per second). It tells you the speed of which the game is playing at. FPS that is at 50-60 FPS means that its running at optimal speed, and the lower the FPS, the lag becomes more apparant as the game's slows down (as the FPS lowers)

It does appear to be that way. It might be something worth looking at, though. If the game is running at 60 (which I assume it is, since the standard is usually 60 or 30, and two of those counts are above 30), then 31 and 39, etc. are unreasonably low. Even then, a low FPS is tolerable, but not a fluctuating one. At most you want it to change by 3 or 4 FPS while playing the game. 8 - 10 is really bad. Try optimising some stuff.
