Emulated games framerate

[Alucardx23]

This is a question about emulated games framerate. A lot of games like Shadow of The colossus allow you to improve the framerate of the game, but other games seem to be capped at 30 frames, why is that? Thanks in advance to anyone that can answer.

In the case of SOTC, "full speed" for that game was significantly higher than what the PS2 could consistently provide. Some games are simply that power hungry. Odin Sphere is another game that notably slows down on its native hardware but runs constantly at full speed when emulated.

Games are otherwise capped for reasons self-evident; delivering a consistent experience and avoiding tearing.
