I really want to enjoy this game but I'm getting 54FPS with drops into the mid 40s at time. No disrespect, because I knew the game's art style before I purchase, but it's not exactly Crysis 3 on the technical side of things. Why is the frame rate so low?

I guess that is pretty easy to explain since the game is made with Unity. and while the engine itself might not have a bad optimisation, I have already seen other games running on Unity with mediocre graphics and low performance.

At least if you compare it to more modern games like Prey, Dishonored 2, etc.
