I began having this problem with my mouse a couple weeks ago, and it kinda made me quit overwatch for a while
I have NO clue what could have caused it.
Whenever i’m in-menu, on google, in battlenet etc. you know, doing “normal” stuff, my mouse tracking/movement is normal and no problems there, but as soon as i join a game and the gamestart countdown hits 0, my mouse begins to not respond properly to the physical movement of my mouse.
Wierd example: When i’m on google, my cursor moves 3 cm, whenever i physically move my mouse 3cm. BUT as soon as a game starts in OW, and NOT in training, only ingame. When ingame i physically move my mouse 3 cm, and ingame it only moves 2,5cm or 2cm. (sort of random how well it responds)
Short summary: When doing ANYTHING else than being in a live match, cursor responds well to mouse movement, but as soon as the game goes “live”, it responds wierdly.
I’m using a razer mamba mouse. (have just updated my razer synapse driver)
