Gratz Tarasis! You are the 1st person to not have had to deal with these 3 issues (that has posted at least) It is nice to know that at least 1 person has been able to play in more than a 25 minute increment of time (and I am not being sarcastic).
I have played 50 hours and I have not yet had the game crash. No leaks. No FPS degradation. It basically just works.
