Hello everyone, I just wanted to point this out.

What OP is talking about is this http://www.youtube.com/watch?v=yr0JICIYyzU. This is a trick used to cover up the sharp spikes that trees tend to show in pretty much all the games. Some work around is ether doing this, high polygon count just for grass, or restricting the camera so it wouldn't notice this (tera does this). Though, I don't think I could ever find myself getting upset over grass, I just wanted everyone to visually see what OP is talking about. Personally, I never noticed this on Just Cause 2 until someone pointed this out. I don't really care if it's implemented or not though.
