Why even bother with the touch controllers? Also bin the mouse in favour of a track ball. If you keep the trackball in the same place you should be able to find it with your eyes closed.
Move the taskbar to the vertical right side of the screen if you can’t go full screen,that will prevent mouse clicks losing focus. Also, try resetting windows explorer to see if that fixes the full screen issue.
If you have VoiceAttack you can call the mouse up at a predefined pixel coordinate.
For you, you could bind your Warthog button to bring up the mouse cursor via VoiceAttack right in the middle of your FOV.
Yep, it’s a bit too realistic for gamer types. Don’t expect to spot much in the A10 without proper use of the targeting pod and binoculars (VR zoom) just like for real. The real fix is to get good.
