Controllers, bindings & display
What can you do if Phantom Blade Zero stutters after using a Bluetooth controller?
On PC, compare Bluetooth against a data-capable USB connection. PC version 1.0302256 includes optimization for Bluetooth-controller stutter. Check the installed version and compare the same scene using each connection.
Make a repeatable comparison
Record how long the controller is connected before stutter appears and whether it also happens without the controller.
Restart using USB while keeping the scene, resolution and quality settings unchanged, then check whether the same stutter returns.
If it persists
Record the controller model, connection, game version and GPU driver. If both USB and Bluetooth stutter, continue general performance diagnosis rather than changing controller settings alone.
