I reinstaled the game to drive D(1TB HDD), due to lack of space on SSD drive C (many users could do it).When I did so I couldn’t adjust resolution to 1920x1080. There was still 1536x864 when I applied the settings (Before when I had the game instaled on drive C everything was OK). There could be a problem with User preferences saved on drive C in My Games folder/Star conflict folder (I copied it to drive D but with no result). When I switched to fullsreen the resolution was adjustable again so this error should occour only in fullscreen window mode. I had the same problem on test server. I am attaching files from C drive.
Try to delete user_config.xml in …/Documents/My Games/Star Conflict
