Performance observation: I've noticed that that the biggest performance hit is on high-population maps such as Mistlock or Lion's Arch. However, changing the Character Model Limit and Character Model Quality between Low/Medium/High does little to affect performance with only a 1-2 FPS change. Now, this makes perfect sense as even the invisible characters are interacting with the environment and thus affect me. However, even if the invisible characters are just standing around, even if they are out of sight I still experience the hit. As soon as the population drops (visible pop remains the same, invisible decreases) performance improves.
