My game has been a little weird ? Whenever I get close to animals or close to the ground I get pretty bad audio stuttering. It gets worse when I'm viewing the animals with the camera. There is also a slight lag too. It's almost not noticeable, but it is there. Things don't improve on lower settings either. When I move up and away from the ground things almost return to normal and the game seems to playing fine. Has anyone else this issue, or know how to fix it ?
