The stutters are caused by the rapid fluctuation in fps.
It is much smoother a solid, fix 60 FPS, wich matches the refresh rate of my monitor,
60 hz, than a higher frame rate fluctuating every second or less from 80 to 100....
Settings included. I get perfectly fluid experience with this in Caucasus, Nevada and PG,
excepting the disastrous Normandy, wich is very poorly programmed, as show many threads in this forum.
