Although rarely, your in-game cursor may feel the need to overcompensate; at other times, it's visual location will not actually match the area it's hovering. To put matters straight, follow these steps:
- Navigate to your game installation directory by right-clicking on your Launcher icon and pressing Open file location.
- Open the bin64 folder.
- Locate the file BlackDesert64.exe, right-click on it and press Properties.
- Go to the Compatibility tab and check the "Disable display scaling on high DPI settings" option.
