Just a tought: could it be that the performance issues with AI traffic are not related to the models, liveries and visuals in general?
I noticed that when I spawn and start FSLTL performance stays ok for the the first couple of minutes. I only see a severe drop once the first aircraft start to move. So my hypothesis is: it is not the rendering of the models but the archaic ATC engine from FSX times trying to calculate taxi routes, arrivals and departures in the background.
I also see one of my cores starts to get hammered after a few moments and I’m limited by mainthread. I suspect the ATC engine is not optimized for multi-core CPUs and limits the sim’s entire performance by pushing one core to its limits with its route-calculations.
I suppose we will continue to see poor AI performance as long as Asobo do not optimize the ATC engine managing traffic in the background.

When I upgraded to the latest version of FSLTL I saw a big performance hit that was not happening with FSLTL v1.0
I reverted back to v1.0 and performance drop is gone, so if you recently updated it and still have the original version, go back to it.
