Start with a direct controller baseline
Connect a supported controller directly to the system and open a practice area. Note the active input type, horizontal and vertical sensitivity, deadzone and any advanced aiming options. Epic documents Aim Assist Strength under Fortnite’s controller settings and notes that options vary by platform. Use the game’s current support page rather than copying values from a different title.
If the title includes several camera modes, repeat the same slow movement in each one. A menu cursor, a free camera and a scoped camera can respond to the same stick differently.
Isolate the adapter and game settings
Reconnect through Titan Two with an unchanged layout and compare the same movement. Then add one mapping or response change at a time. Watch input and output separately in the Gtuner IV Device Monitor. If the outgoing stick moves while your physical stick remains still, inspect the active slot and other connected input devices before changing game settings.
Check whether gyro or another input mode is active. Epic’s Fortnite support page explains that gyro disables aim assist in that game. Other titles can handle this differently. Keep a note of the game build and your original settings so you can distinguish changes caused by an update from changes made to the adapter.
Trace movement while the stick is at rest
If the camera drifts in one direction, let the controller rest on a stable surface and inspect both stick axes. Compare the direct connection with the neutral adapter profile. Repeat with another controller if one is available. Keep the smallest intentional movement in your test to see whether an increased deadzone costs you fine control.
