Well I am currently building a home cockpit... it isn't a replica etc.. it's a universal thing.. anyway moving on to the question

I am going to have FSCommander running and I want it connected to flight sim x which, you know where I can look at FSCommander and see my plane on FSCommander with the details etc.. and also the other planes which are on multiplayer (AIBridge). I understand I need FSUIPC4? First question how much does this cost? , Second: what exactly does this do? (<- Sorry if that is nooby)

Also using this software [FSCommander] will it take up alot of CPU on my computer? and resulting in a frame rate drop of around more than 10? I get like 25-30 just now
