I was wondering how to exclude certain 3rd party aircraft that may be bringing my perf down more than I'd like . . .Noel

You got a top of the line system (almost), should be no aircraft that will bring your performance down! LOLSeriously, I assume you mean one you use for AI that is a framerate hog and it is bringing your FPS down, correct? Just delete that aircraft or change the name in the aircraft cfg so that it doesn't match the flight plan name and it won't show up as AI. Of course you could just use AITM utility and reassign another aircraft to that flightplan. I only use PAI, Aardvark and FSP aircraft for AI, learned the hard way that it kills the FPS with any other, and no matter what others say I see hardly a difference between any of the mentioned models on impact, about the same. Rule of thumb, if it has a VC it probably won't be good for AI.Regards, Michaelhttp://mysite.verizon.net/res052cd/mybannercva1.jpgCalVirAir International VAwww.calvirair.comCougar Mountain Helicopters & Aviationwww.cgrmtnhelos.com

Double click on that plane's aircraft.cfg file and change the title= line (I add NoAI to the end for "No AI"). The only problem with this approach is that any Flight you created for this plane will no longer load the plane - you'll have to do that manually after starting that flight (and then resave the flight).Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Actually, I high percentage of AI aircraft are still very poorly made & will bring a 5Ghz system to a crawl if there

Thanks folks these are helpful tricks.Noel
