I have a 1070 GPU with a i7-6700 and I play on 1440p resolution but the game seems to run at only 25 fps. Is there a way to run the game at 60fps?

I also use the wide screen resolution fix
No, this game was created long before 60fps was even a thing for video games. They will only play at 30fps maximum, that's the way the engine was designed.
