@ami888 Just to be sure, please test the default Sunset Valley in another clean user folder, as before. Don't add anything to that folder; the point is to see how the game performs with only EA-provided content. And make sure the framerate limit is being respected. If you do play in windowed mode at all, you'll still need to use RTSS to enforce the limit.
If you get another crash, please look for related entries in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. For any error that happened while you were playing in this new user folder, right-click and select "View technical details," then copy the info and paste it here.
