After having some problems with various things I noticed that I only seem to get the DSD bug (where you get a beep beep beep at random times which you usually can't stop, even with DSD and AWS disabled) when I have tweaked the engine ini with this: r.ViewDistanceScale=10. I already read someone else couldn't finish a scenario with this tweak enabled. I also had problems with a scenario which I solved by removing all saved ini's and files and hence I also removed this tweak. Maybe that was what actually solved my problem? Maybe someone who also had the DSD bug might check if he or she has r.ViewDistanceScale=10 in the ini and what happens if this tweak is removed? BTW Are tweaks like this officially supported by Dovetail?
