After not having used FS for several months I recently reinstalled FS04 and now I'm thinking about adding AI traffic again. I had used ProjectAI packages in the past, but since there are so many other designers of ai-models (AIA, ARNZ, CDAI, FSP, ...) I'd like to know if there are any differences when the effect on framerates is concerned.How good are PAI models compared to those other designs?Is it worth the work to search for all the models, textures and flightplans instead of just downloading a PAI package?Thanks in advanceRick

go for Aardvark, CDAI, Dee Waldron, Henry Tomkiewicz, EvolveAI, FSP ..in my opinion it's definitely worth it to hunt for repaints and flightplans yourself instead of using PAI packages .. i use mostly MRAI plans, and if PAI has a package of an airline not available at MRAI, i install that package and then replace the PAI models with the models mentioned above .. PAI is good if you want no-brainer AI, but if you're willing to spend some effort, then go for the manual way .. all models mentioned above should be more frame rate friendly then their counterpart PAI brothers and sisters ..
