the screen on my game apps areall zoomed in after New software update?

I just updated the software on my Galaxy S6 and since then all the games I play , the screens have all been magnified and I haven't been able to adjust it to the original size. It cuts off 1/3 of the screen and makes certain apps unplayable. What should I do? Any help is getting appreciated! Thank you!
