Army of Two The 40th Day 60 FPS Patch doesn't work correctly

[fog13k]

Hi there, i want to report an issue about the 60 fps patch of this game, the frame counter does indeed show 60 fps when activated but internally the game still runs at 30 fps, tried with different Vsync settings and nothing happened.
Know that other settings on the patch work correctly and all the other patches for other games work correctly, it's specific to this game, can i get some help please ?
