It seems that the game cannot properly synchronize with the input from the peripheral and causes issues such as stuttering. Dark Souls, in the past, had several issues when a controller was used instead of a keyboard. If you are using a controller to play your game on your computer, it may be the cause of the problem. Note: If this doesn’t rectify the issue, consider performing the same steps for USB Input Devices. Now launch Dark Souls 3 again and see if the problem is resolved.
Also, the drivers should be updated to the latest build as game developers always optimize the game according to the latest version.
