Ok. It's happening in any aircraft. Tried with the default C172, Baron 58, Airfoillabs 172, JustFlight P28R...and got the same issue.
The xp11 graphical settings is reporting 4160 mb of usage, while my gpu have 8 gb of vram.
Also tried to reduce the texture resolution, restarted xp11 (now with 2513 mb of consumption) and it keeps freezin when I click on "settings" of the GTN plugin.
Here is the content of the RealityXP.GTN.ini file (I hope is it what you asked for, hehe) :
;//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
;// Reality XP Keyboard Shortcuts Configuration File - v1.0
;//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
;//
....
Another issue that I realized is the OBS (Open Broadcaster Software) is freezing the XP11, but only when I have rxp plugin inside the plugins folder on plane 11. It seems a conflict, but just when realityxp plugin is activated on XP11.
Anyway, thanks for the attention!
