Thanks for the replies. I downloaded the free FMS flight sim and have used it with a standard joystick, it's fun to play with but not very close to the real thing and unless I spend $40 for an adapter can't use my TX. I think you are right, unless I use FMS or Realflight G2 I am going to have to upgrade my video card. I'm going to start looking and see where the best performance/dollar line is.
