1: Hill with Devil's Castle as seen from the NW. Low polygon count near the edge of my FOV.{F849553}
2: The hill fills in with trees and detail when I turn slightly right to face it. {F849554}
3: Same hill with a low polygon count. {F849556}
4: The issue disappears when I turn to face the hill.{F849564}
If it can be of any help, the FOV in my profile settings is: fov=0.95993;
