I was working with an old Dell Keyboard and Mouse when I first played MCC on PC. Mouse and Keyboard were working just fine. Though until upgraded to them to a Corsair Keyboard and Razer Mouse the input lag screen tearing began. I use Controller, no issues with controller. Movements from controller inputs correspond accurately as to what’s on screen problems only occur with mouse and keyboard. I know you already thinking and yes I already tried the mouse and keyboard with other games. Splitgate and the Halo Infinite Flight had no issues whatsoever. If someone else had the same issued and resolved it please message me, I’m absolutely perplexed by this issue.
