The Coalition has patched Gears of War: Ultimate Edition to take advantage of yesterday’s Windows 10 update, which paved the way for unlocked frame rates in Universal Windows Platform games and allowed for G-Sync and FreeSync compatibility.
V-sync, an option designed to eliminate the screen tearing effect by synchronizing a monitor’s refresh rate with achievable frames per second, can now be disabled, enabling unlocked framerates.
