I totally agree with DrZGard. After flying with the TH2Go, single monitor flying seems like tunnel vision. Then add the IRTrack, it is as close to real flying you will get inside of a professional simulator.
I get good frame rates with my set up. On average high teens to mid twenties with sliders mid range to three quarters over.
Now, what is this about adjusting the cfg to make the lights look smaller? I have always thought they were to big.
