I also have a copy and have to agree with everything said so far..especially the graphics which are the best I've ever seen on any flight sim to date.
BUT
After some 20 mins flying I get a pale ble screen which freezes the whole system and only a hot reboot will re set.
Bah Humbug!!
It is a bug withy the software apo!
I am running powerful enough system but issues with the graphics card I have await a de bug from UBIsoft
