DarkRP server client side fps drops at max players.

[Retalak]

I have a 17 slot DarkRP server and it seems to have very poor FPS once max players is reached. After it maxes out, slowly everyone's FPS drops until it's unplayable (about 10-20). Also the FPS magically is better in the ESC menu.

Heres my CFG:
