Project 1999 - Distance issues?

Hello, I'm having an issue in game that I'm not sure can be fixed. Basically what happens is, when a player, npc, or monster is a certain distance away, I'd say maybe 15+ feet, they lose all animation/movement. This becomes a problem when I'm kiting, and the mob looks like it's just standing there, until it reaches a close distance, and then it appears to warp on top of me. Is there a way to fix this to where everything retains it's movement/animation, regardless of distance? I have my clip plane turned all the way up, and that is the only solution I could think of, which of course hasn't worked.
