can you give a advice for fsx ai traffic? best fps, easy to use and hdd requirement is important for me.can be freeware or payware.thanks

Since this question comes up about once a week try doing a search and you will find many, many post on the very subject where it is hashed out.Frankly there really is no best, it all comes down to what is important to you. What I find the best, may not suit you at all. However I would compare MyTraffic X and Ultimate Traffic 2, as those are probably the leading 2 payware products on the market now. Personally I prefer UT2 because the AI fly actuall flight plans and the schedules are based off of real world airline schedules, so you will get the right traffic and the right airport at the right time. I also use some WOAI to fill in some of the cargo that UT2 is missing.For free the best would probably be either WOAI - World of AI http://www.world-of-ai.com/ or PAI - Project AI http://www.projectai.com/forums/

thank you for your advises
