DCS generally works fine for me except in one area - when I go into the Adjust Controls Screen I have regular lock ups that need a hard restart about 75% of the time or resolve themselves after a minute or so about a quarter of the time.
This happens in multi, single player modes and in the controls section of the pregame seettings tab.
This evening (F4 release) it has crashed about 15 times, SO annoying! Geforce experience shows CPU and GPU use both low (under 50%).
