Low Fps

I have a i7 2600, gtx 1050 lp, 8gb of ram and am using a 1tb hard drive. I was just wondering why I was getting 15-20 fps on my game when im seeing people on youtube with about the same specs maybe even worse specs getting double maybe even tripple the fps I am getting.

Thank you…same here.

Buuut…if you put full screen off…than you get 60 perfect.turn it back on it goes on 30 to 40

Same here.
Full screen off all good.on 30 to 40 fps.

How the heck are you playing Forza 4 on a PC?

Edit : Forza Horizon 4 moved to correct forum.
