Havent seen the new GUI yet, but you want Aero enabled. So choose an Aero theme in Windows, do not check the new in game option if doing so disables Aero. Obviously you are running Windowed Mode.
Yes Aero (at least in standalone-haven't installed World yet) gives a significant FPS boost when running additional screens in Windowed Mode. Something to do with running DX optimizations on all windows.
After setting Mark Points, you have to set SPI to Steer Point (TMS Down Long), then you can cycle the Mark Points by cycling Steer Points (UFC Rocker, HUD as SOI then DMS Up and Down, CDU Rocker).
I found the metal hitch, but now I need the two metal rings. Are you still using the Cougar, or would you be willing to trade or sell some of the innards related to the AB (which would leave the throttle working perfectly just without the detente)?
Many thanks
