Hey I tried to look to see if anyone else had this problem, if so I'll be sure to close the thread.
Anyways, something happens in every Sins beta game I start up, around mid to late tech (has nothing to do with amount of time played) and essentially causes 1:1 stuttering (2 seconds of stuttering for 2 seconds of normal play usually)
I checked, and its not some odd process error, and restarting it or steam does nothing. I don't believe its a memory problem on my computers part.
I've tried to nail it down to a single tech upgrade but have been unable to sadly, changing the graphical settings also does nothing.

Has anyone else had this problem or something similar?
