like reduct a little the movement to prevent the pupils to make funy angles whem the PC in just in front and the crosshair force to much the border

That said, I've had to stop using it because it is so disconcerting to have people staring at me through the side of their heads. If there was any way to change the angle of NPC eyes from parallel to, say, half the angle from where you're looking, or even just to put a "stop" where the iris hits the side of the eye

Some people would roll their eyes so far they looked to be possessed.. and when I look to someone's left, it seemed weird that they would look to their right.. like they weren't paying attention to me. I'd like to see the X axis on the eyes reversed, so that when I look to someone's right they also look to their right. I would also like to see the movement range for the eyes to be reduced so that their eyes don't roll so unbelievably far out of the normal range.

Restrict the eyes' rotation a bit more. It's disturbing to watch people's eyes roll back like that. Or make them chant satanic incantations when that happens.
