Hello everyone ,I would ask for a little help for this game, which I downloaded a few months ago but only recently I had the time to play seriously. I would like ask if anyone can help me with a problem I am having since I switched from Windows 7 to Windows 10; With Windows 7 the game worked perfectly but now, when active the full screen in the game options, the game continues to work in window mode ; I tried to run it in compatibility mode with Windows 7 and with administrator privileges, but there was no improvement. someone could give me some ideas to try to fix this issue?
