I watched a video where someone compared the performance between the FSLTL AI models and the FS Traffic Models, saying that the FPS were better using the FSLTL injector, and specifying the FS Traffic AI Models.  I checked the price the FS Traffic and it is around $40. If the difference in performance is one or two FPS, that seems like alot of money to spend for a small improvement. I posted this to see if anyone has tried this,and did you see a substantial gain in FPS with the FS Traffic models? 

The liveries are much better with the FSLTL models, I wouldn't bother swapping to the FS Traffic models for a miniscule gain. 

I confirm this is not worth it, FSLTL is enough for the moment.

I have been using FSLTL since it was released and, like others, I have found it a great addon. However, I am not prepared to take the big perfomance hit that comes with it. Even with very conservative settings I have been experiencing no less than 25% FPS hit. OK at some airports, but at larger airports I was finding my frames drop to about 24, and that's unacceptable.  I'm rather disappointed and have returned to AS Simple Traffic and I find that a pretty good compromise.
