I think I’m in the same boat as Malediktus. OOM crashes after 4 to 5 hours of play, they’ve all occurred in LA or during Tequatl fights. I’ve probably crashed around 10 times now since culling was removed, never had a crash before that and I’ve been playing since release.
Run all my hardware through various stress and error tests and they’ve all come out fine. Tried lowering in game settings too and still crashing. I’m gonna give Kyllaa’s suggestion a go and set my max prerendered frames to 1 and see if I have any luck.
If it helps narrow things down I’m running an i7 930, 16GB RAM, GTX 660Ti video on a 2560×1600 monitor.
Edit: I’ve also tried a -repair which turned up no issues.
Got 2 of the requirements at the same time as well (daily champ slayer and leveler) to hit 5/5 and no chest here either.
If getting 2 achievements simultaneously isn’t the issue, could it be the tracker display? I had it set to display my Dive Master progress instead when I completed dailies.
