It works beautifully for 2 hours and then almost consistently after about 2 hours of game time it will crash with Fenris - doesn’t matter what I’m doing in game. I launch and again it’ll run fine for 2 hours.
Clearly behavior indicates some type of memory leak since it’s time bound. Frustrating but it’s so consistent that as long as I quit the game and restart before the 2 hours I can play a long time. It’s not ideal but it is a workaround.
I have 64GB of RAM so maybe that’s why I last 2 hours, others may last less time.
