Lorsque je personnalise la météo en maximisant les nuages, précipitations, vents et minimisant la visibilité (donc le vol de rêve :)) l'écran, après 3 minutes de vol, devient gris ou noir rendant inopérant l’ordinateur...Et ce avec n'importe quel add-on : PMDG, Captain Sim, Majestic Sofware, Carenado,...

Je me rapproche donc des experts en configuration pour trouver une solution...:)
