Mouse movement causes stuttering in the game.
Mouse movement causes stuttering in the game.
I have a Gigabyte 1060-6GB, Ryzen 7 2700x, MSI B450M-PRO M2 motherboard, G.Skill 2x8GB at 3000MHz, and Corsair CX650W power supply. This issue exclusively occurs in Fortnite: Battle Royale. While I achieve approximately 160 FPS, sudden unplayability arises when I move my mouse/camera until the movement ceases. Consequently, I am unable to aim effectively.
Screen tear can typically be resolved through Vsync or a framerate cap. However, Fortnite is an eSport title where limiting frames is undesirable; therefore, Vsync may not be suitable without a high refresh rate display. Switching to Windowed Fullscreen versus Fullscreen may resolve the issue, and if that fails, employing a framerate cap using Nvidia Inspector set slightly below the average frame rate can be attempted. Further troubleshooting includes reducing mouse polling rates on game mice incrementally, ensuring updated drivers (including latest Nvidia drivers).

Reducing my polling rate decreased CPU usage and now I can play normally. Changing from 1000Hz to 500Hz resolved the issue. Thank you.
