Hey guys, my GTA 5 is stuttering so bad when I am in the plane and I am flying up. Flying down is okay as well as hitting high speeds. I get these stutters only in planes while flying up. My pc specs are: ryzen 5 3500x, gtx 1070 and 8 gigs of DDR4 3200MHz ram. Do you think that I need more ram? Or is it something else that is bad?
