Bnz IMO if you can't see if he's right side up at 400 yards thenA your monitor is too smallB your resolution is set too highC Both!Gunery is determined on your FE, if you see a single dot, its going to be very hard to hit it. But if you have a larger monitor, and lower resolution setting, so you see a bigger dot, its going to be a lot easier to hit.The higher you set your resolution, the better things look, and the smaller the planes get.What is a single pixel dot at 800 yards in 1600x is 4 or 8 pixels at 800x.But don't take my word for it, check it out yourself. Key is to find a balance that you can live with, and still see to shoot.
