Having a play with this now. Overall, FPS is ok - but there are a few stutters here and there. I'm playing with .ini files at the moment, trying to stop my POV hat from changing the view as I use TrackIR and want to use the POV hat for trim changes. I think the entries below in ConfUser.ini might do the trick:
[HotKey viewPan]
NumPad-4=PanLeft2
NumPad-3=PanRight3
NumPad-2=PanDown
NumPad-1=PanLeft3
##Pov225 Joystick+Pov=PanLeft3
##Pov270 Joystick+Pov=PanLeft2
##Pov315 Joystick+Pov=PanLeft
##Pov0 Joystick+Pov=PanUp
##Pov45 Joystick+Pov=PanRight
##Pov90 Joystick+Pov=PanRight2
##Pov135 Joystick+Pov=PanRight3
NumPad-9=PanRight
NumPad-8=PanUp
Pov180 Joystick+Pov=PanDown
NumPad-7=PanLeft
NumPad-6=PanRight2
NumPad-5=PanReset
I've commented out the applicable entries, let's see if it works!
I'm not playing with any graphics settings in the .ini files as the issues may be patched out pretty soon. I am looking at onscreen font sizes, however.
