If your game is flickering on Windows 10, you need to change the screen size from Fullscreen to Window mode. Unfortunately, it's not possible to fix this issue in Fullscreen mode. This is because we are dependent on external game developers, who can't always fix their games for newer Operating Systems, such as Windows 10. You can change the screen size in-game by choosing Window mode in the Options menu. Alternatively you can press both the Alt+Enter key during the game.
