There is no support for 21: 9 format monitors in full screen mode. In full-window mode, the resolution of 2560 × 1080 is set, but freesync requires full-screen mode. Due to the work in the window, the monitor function does not work correctly and the screen flickers during the game. if you enable the game mode in full screen, the screen resolution is set to 1920 × 1080, the picture is stretched and does not look serious, but the screen flickers stop and the freesync function works fine. It seems more than strange to me to ignore modern technologies in 2019, and in this case, it does not care about users with 21: 9 and 32: 9 monitors.
