S!
Also can try this...First set the settings you want and exit game, clear cache. Then open BOTH conf.ini files, located in X:\documents\1C Softclub\il-2 sturmovik cliffs of dover\ and the other in X:\..\steam\steamapps\common\il-2 sturmovik cliffs of dover\ Then line by line compare the files and check for differences. I found some and changed so that BOTH conf.ini are similar now. It MIGHT help and as it is easy to do worth the try IMHO
