My system has Just Flight’s Traffic X and a few other AI traffic addons installed. They together brought a lot of AI aircrafts and traffics, which makes the default ones redundant.
To reduce overlapping and enhance system performance, the TrafficAircraft.bgl under X:\Microsoft Flight Simulator X\Scenery\World\Scenery was moved to a backup folder so that no standard AI traffic is loaded.
To restore, just putting back the file to the original folder will do.

Dear Tom,
Is this same trick required for myTraffic?

Hi Ircghost, I don’t know since I don’t have myTraffic. But it won’t hurt to try the trick.

No, I didn’t say that. I meant if you have Traffic X, taking out default AI would reduce unexpected problems like I encountered before. After all, you have to test it yourself.
