I am also having a huge problem and my specs IMO are good.
-i7-8700k
-EVGA geforce 2070 super
-32gb ram
I can fly, but for a limited time. The tutorials i had no problem (for the most part)
When i choose a destination to travel to on my own, i usually crash about 5-10 min in. (Any place that tends to have a lot of houses/trees)
Whats odd is the game runs great while its working, then itll start to stutter and freeze up then it crashes.
I have it through game pass but on my PC, so its not a huge loss for me, but i feel for others who paid for this game. I dont have any problem with any other games but this one. Granted i know the game takes a lot to run, but shouldnt be this unplayable. Would love to support the game if it was playable.
