With G2, I wished my model flew as good as the sim.... with G3, I wish the sim flew as good as my model. I find every unmodified model I try in G3 to be nearly impossible to fly.
What version are you running? It is displayed in the G3 launcher. What is your physics quality set to? It is found in the Simulator menu. Click Simulator->Settings->Physics->Airplane Physics Quality. Make sure it is on "highest."
I am running it on the same hardware that I ran G2 on...
What hardware is that? How many frames/second are you getting? (in View->Gadgets->NavGuides)
and why won't the new controller work with G2?????
For the G3 Interlink to serve its intended copy protection function, we had to change the way RealFlight communicates with it. There wasn't a good way to make it backwards compatible. Sorry about that.
