When in game, the cursor won’t lock into the game window, even in first person. This causes it to go off onto the second monitor, and force me to make large left turns to avoid moving my mouse onto my right monitor. This happened after updating my graphics card drivers (GeForce Game Ready Driver v428.81).
Unreal sometimes can do this, I find. If you press tab real quick you should lock your cursor back in. I’ve been doing several fixes for this, but sometimes it just happens with multi-monitors.
Hi! Thank you for your solution, however, I found out Rainbow Six: Siege did not close properly, and after closing it through task manager, the game instantly kept the mouse locked inside the window.
If this happens again, and there is no game in the background, I will try this!
