That's what i was thinking, but I reduced the so traffic density to 10 and all gates where still full.
Again, nothing to do with the GSX or the scenery. If the gate are full, which is clearly only controlled by the traffic product you are using, they are full...nothing we can do about it, you must act on your AI traffic product to control their density.
Are you SURE you are on 10% on Traffic ? UTLive has its own scenery density, which is separate from the one of the sim.
