Maybe you know that Lockon takes a lot of FPS during the mission, this is not nessecary because it may slow down your computer.
So to fix this you can do the following thing:
Go to the Graphics.cfg and scroll down to bottom.
Than add this at bottom:
MaxFPS = 45;
Of course you can fill in another number, but 45 is good and stable.
Thanks to Sawamura who told me this kind of mod
