Deadzone Settings
Dead zones define how much physical movement is ignored before S2 begins outputting a stick or trigger signal. Properly tuned dead zones eliminate drift, reduce unwanted movement, and make stick response feel consistent across different controllers.
Controller Stick Dead Zone
Two controllers can have their dead zones configured: the authentication controller (plugged into USB1) and the main controller (USB2–4).
| Parameter | Range | Description |
|---|---|---|
| Inner Dead Zone | 0–100 | Movement below this threshold is ignored. Higher = more stick movement required before output starts. |
| Outer Dead Zone | 0–100 | The maximum position before the stick is considered fully tilted. Lower = reaches 100% output sooner. |
Authentication vs. Main Controller
| Controller | USB Port | When to Adjust |
|---|---|---|
| Guide (Auth) | USB1 | If the authentication controller’s stick is visibly drifting on the IO Monitor |
| Main | USB2–4 | If your gameplay controller’s stick feels too sensitive or not responsive enough at the edges |
Trigger Dead Zone
Configure the inner and outer dead zone for analog triggers (L2/R2) on connected controllers.
| Parameter | Range | Description |
|---|---|---|
| Trigger Inner Dead Zone | 0–100 | How far you must pull the trigger before output begins |
| Trigger Outer Dead Zone | 0–100 | How far before the trigger reaches 100% output |
Trigger dead zones are useful for games where you want a hair-trigger response (lower inner dead zone) or need to prevent accidental trigger activation (higher inner dead zone).
Numeric Input
Every dead zone slider supports precise numeric entry. Tap the value to open an input box and type the exact number you want — no need to guess with the slider.
Dead Zone Shape
For the main controller sticks, choose between two dead zone shapes in the Game Settings page (alongside keybinding configuration):
| Shape | Behavior |
|---|---|
| Circle | Equal dead zone in all directions. Best for most games. |
| Rectangle | Independent X and Y thresholds. Useful for games with strong horizontal-vertical aim asymmetry. |
💡 Tip: Start with Circle and a low inner dead zone (5–10). Increase only if you notice stick drift on the IO Monitor.
Per-Game Differences
Different games interpret stick input differently. A dead zone that works for one FPS may cause sluggish aim in another. Always test after changing:
- Open the IO Monitor to see real-time stick values.
- Move the stick to the edges — verify both X and Y reach 100%.
- Release the stick — verify both axes return to 0.
- Adjust the inner dead zone up if values do not settle at 0, or adjust the outer dead zone down if values do not reach 100%.
⚠️ Warning: Setting the inner dead zone too high can create a “jump” when the stick passes the threshold. Keep the inner dead zone as low as your hardware allows.
