Not rendering != despawn entities and respawn entirely new entities every time your camera changes direction. They also advertised it as NPC's each having their own unique routines, etc. Talk about overpromising and underdelivering. This broke immersion too much for me to play the game. The second I hit the city and saw how NPC's were handled, I was done. It's unfortunate, because I thought the map design, sound, graphics, and gunplay all seemed really good.
