Persistent Game Freeze/Crash to Desktop

Anyone else experiencing this? The game performance in the pre-release build seems to be way more stable than the now released one. Even people involved in the testing prior to the release have given feedback that the released build is unstable and in a lot of cases simply unplayable.

In my case I haven’t been able to keep the Sim open longer than 30 minutes without crash to desktop so far, and even on my record length of 30 minutes it froze twice for about 10-15 seconds each time… but managed to recover.
