I have had RealFlight G3.5 for quite a while. It has been running fine.
Today, when I ran it, it loaded the terrain fine then the Airport Objects took around 3 seconds each.
WHen it finally loaded, the response was a couple of orders of magnitude worse than it used to be.
It took seconds to respond to any controll on the Interlink.

I speant over an hour on the phone with Tech Support. I tried several different versions of the display driver with no change.
To my knowledge nothing has changed on the PC since the last time I ran it.

Anyone got any ideas?
