My system is a quad core q9550 @3.44 ghz with liquid cooling normally when running mass effect 2 or other cpu intensive tasks ive never gotten close to getting the overheating alarm on any core but after 30 mins of beta 3B im getting it constantly.

Putting up the process debugger i can at tops find 3 threads running so seeing up to 60-70% cpu time used is quite worrying, i do suspect you left a while loop running when you went home for the weekend guys.

And ive had quite a bit more stalls in the game, sometimes it just takes a long time to think. And if my sovereign attacks a spider or something the spider just disappears no xp or anything. Especially noticed this if using the cloth map to navigate, ill click somewhere in the shroud, an enemy is there my soveregin go to attack it pauses for a moment like its about to crash then the enemy despawn and the game moves on.

City structures despawn, this is a real annoyance and has been through beta 2, buildings are built but despawn and show as empty lot maybe a bit of smoke when zoomed in.
