Pilotwongs 64 framerate

[Dj ReoF]

Hi, i'm playing to this game.
In 1.6 version it runs well but in 2.1 it's like to playing a speed up game.

How can I fix this issue?

Edit:
Oh yeah, and it keeps slooooowing down a lot when i press a button to go from a menu to another and keeps crashing when i finish a mission and i click on Next (in 1.6 it was good)

I just have to ask... they made a Pilotwongs 64 game? Is it some foreign and unknown version perhaps?
