Hopefully some one can answer a couple questions for me. I am using both some default FSX AI aircraft (less than 20%) as well as some from MyTraffic. I have a moving map that I can zoom out and I see that I have AI traffic over 100 miles out. Is this much AI traffic impacting my performance? If so, is there a way to tell FSX to only use AI aircraft that are 50 miles out? If this is a question already asked, I apologize but could not find a reference. If this is a "stupid" question please accept the fact that I am a "newbie" to tweaking FSX and have learned a lot thanks to AVSIM's forums. PLEASE do not tell me about another alternative to FSX, I am in the FSX arena to stay for awhile. THANKS!!!
