Re: [Flightgear-devel] On line Multi Pilot freezes

[Maik J. <mj...@gm...>]

Hi Nick,

I think the AI-Objects (multiplayer Aircrafts are such things) in the 
ground-cache cause this behavior.
@Mathias: I know, that you are working on optimizing the ground-cache 
for such things. Is it much effort, to disable the AI-Aircrafts in the 
groundcache up to that?

Best regards,
Maik
