I bought the disk version of this game and upgraded the GPU and PSU to meet the min specs of my PC so total investment about £400. The features of this game are brilliant but it has had so many crashes to desktop that it is totally unreliable and with some aircraft, unusable. Generally I’ve found the Robin 400 is playable in GPS/VFR flight but it consistently crashes when flying the Citation and the Diamond. Not had the opportunity to fly any of the other aircraft. I’ve made numerous CTD reports to Zendesk and followed many recommended solutions including updating drivers, repair, reset and reinstall of the game but still the same problems. These solutions have been from Microsoft, msfs forums and general internet searches. The problems with this program are widespread looking at comments by others but admittedly others still are finding less issues so I’m at a loss to understand why these difficulties occur seemingly erratically. I’ve found this program very unstable and the support from MS slow and ineffective. Very frustrated having spent so much money obtaining this game. If they can get it working properly without constantly crashing it would make an excellent buy but right now I would not recommend it as it is by no means the finished product.
