I've been having issues with my mouse in rainbow six siege. Whenever I join any game type (t-hunt, multiplayer) my crosshair is not working properly (skipping frames, messing my sensitivity up). Before Demon Veil launched I could've fixed it by simply opening my mouse software, but now it no longer works. I tried reporting the issue to r6fix, but got no response. The game is literally unplayable.
My mouse is Steelseries Rival 600 and I use SteelseriesGG software. Please help.
