I tried to play Gears of War 5 on PC whenever I press key on the keyboard the game starts lagging but when I try with the controller it works fine. I tried moving the mouse it does fine. if I just press a key it starts to lag and stutter
Fix that worked for me which i found in this forum: If you are using Razer Cortex, close out of the program before starting Gears 5. Completely solved my issue.
Thanks that resolved my problem
