1) To answer queston 1, it is necessary to understand what Traffic X does do ... and conversely what it DOESN'T do. What it does do ... Traffic X does install AI planes and flight plans. To do this it simply copies some airplane models and liveries in to some folders, and then installs an AI traffic database file ("TrafficX.bgl") for those planes which FSX uses to fly the planes. What it doesn't do ... Traffic X does not alter the FSX software or how it works in any way. All aircraft systems such as instruments, dials, knobs, NAV, GPS, VOR, NDB, ILS, etc are all untouched. None of these have anything to do with adding AI planes to the sim, and therefore Traffic X doesn't have anything to do with them. In other words, the issue you describe setting the autopilot to NAV (and switching to GPS) and the plane subsequently flying off on a different course to what you are expecting has nothing to do with Traffic X. -------------------------------------------- 2) Bouncing is a common indication that your FSX settings are up too high and as a result your PC is stuggling to cope. What's happening is that you are seeing things bounce as each individual scenery layer is being loaded, one at a time, in order, on top of each previous layer, (ground, then trees, then hills, then water, then clouds, then aprons, then runways, then buildings, then bridges, then autogen, then AI planes, etc etc etc). As each layer loads, you see the bounce. In this case, yes, this could be due indirectly to Traffic X. By installing Traffic X you have added lots and lots of extra AI planes so the FSX program now has to do lots and lots of extra work. And if your FSX settings are up a little too high, this is now causing the system to struggle. Note that this issue could also result from adding any other add-on ... the more you add, the more the system has to do. The good news is that if you are patient, eventually all of the scenery layers will finish loading up, and the bouncing will stop. However, if it bothers you, then you can get rid of it simply by winding your FSX settings down a little. This may mean lowering your Autogen setting, or your detail levels, or reducing your AI traffic sliders, and so on and so forth. Reduce your settings until the system is no longer struggling and the bouncing will stop. -------------------------------------------- 3) CYYZ is reasonably populated by planes. It is certainly not empty (zero planes like PHNL [Honolulu] as johnep mentioned). I have my FSX airline traffic slider set at 60%. When I loaded up the sim and went to CYYZ I saw a range of different airlines there, and a reasonable number of GA planes too. Try checking at different parts of the day, morning, day, dusk, night. The airport should have a good number of airliners from different airlines and a reasonable number of GA. -------------------------------------------- 4) When you first load up the sim, yes, it is normal for lots of aircraft to start contacting ATC and pushing at the same time. The sim has just started and lots of AI planes got loaded. There is now a lot of AI planes and schedules for the sim to sort out and keep track of, and it will take a few minutes for the sim to "catch up". After a few minutes, things will settle down and the traffic flow will work as you expect. But in those first few minutes, yes, it can certainly be a little "crazy". And this also goes back to the answer to question 2 ... now that the sim has a lot of AI to sort and keep track of, its adding an extra workload to the sim ... an extra workload which places additional strain on your system. In your case, your FSX sliders sound like they are up a little too high to cope with this newly added extra workload and this is showing itself by you seeing "bouncing". It can certainly be a fine balancing act adjusting the FSX sliders to get the numbers of AI that you want to see, the graphics settings that you like, and making sure you are not straining your system too much.
