So I'm trying to lock the game at 60 FPS in window mode, as when I use a helicopter, it moves super-fast. I tried to use dxtory, but apparently I have to buy a license.

Is there any other way of being able to lock the game at 60 FPS in window mode? I am running the game on Windows 10.

I've been succesful with locking the FPS with dxtory without a licence.

My DXtory screenshot where to lock the framerate to 60:

So the trial doesn't expire then? Just that I didn't want to click on the Experience Trial button just in case.
