ACC controller settings: the console reference

Most ACC players on PS5 and Xbox Series X|S play with a controller. The default controller settings are usable but not optimal — drivers who leave them at default give up several tenths per lap to drivers who tune them. The metric that improves most when settings are right is consistency: smoother, more modulable inputs translate directly to lower lap-to-lap variance.

The settings that matter

Steering speed. How quickly the virtual wheel responds to stick input. The default is too fast for most cars — small stick movements become large wheel movements, producing jerky mid-corner corrections. Most fast controller drivers set this in the 40–60 range. Lower values feel heavy but produce smoother inputs and better stability.

Steering linearity / gamma. The non-linearity curve of stick → wheel. A higher gamma means small stick movements produce proportionally small wheel movements (more precision near centre); larger movements expand proportionally. Most controller players benefit from a slight non-linear curve (gamma 1.5–2.0). Default is closer to linear.

Steering deadzone. The dead area around the centre of the stick. Stock controllers develop minor drift over time; a small deadzone (5–8%) accommodates this. New controller: 0–3%.

Brake gamma. The non-linearity curve of trigger pressure → brake input. Most analogue triggers produce too much initial brake pressure for too little finger movement. A brake gamma of 2.0–3.0 flattens the curve so you can modulate at the threshold-braking zone. Default is closer to 1.0 (linear) and feels grabby.

Brake / throttle deadzone. Trigger play before input registers. Small deadzones (3–5%) remove inconsistency from very light trigger touches.

Traction Control (TC) and ABS. Not controller settings per se, but set per car. Default TC is level 3. For controller players, TC level 4–6 (depending on the car) is often the right starting point — slightly slower on exits, significantly more consistent. ABS at default (level 3) is correct for most controller players.

Stability Control. ACC's training-wheels assist. Most fast controller drivers run 0 — it costs lap time and masks handling issues. New drivers can leave it at 10 while learning a track, then dial it down.

The PaceBoss-verifiable signal

You can't directly measure "controller settings are right." But the downstream signature shows up in the data:

• Lap-to-lap consistency rises. Adjust brake gamma and start braking more consistently: S1 (entry-heavy sectors) tightens. The pace-trend chart's spread narrows.
• Sector ranks shift. A driver who was spinning exits on low TC may regain S3 by raising TC — accepting a fractionally slower peak in exchange for every-lap consistency.
• Theoretical-best gap matters less. If your peak lap is good but your typical lap isn't, consistency is the issue. Settings often unlock the opportunity for technique to land — the verification is whether your numbers move.

A change protocol

Change one thing at a time. The pattern:

1. Baseline. Drive a 10-lap stint with current settings. Record best lap, consistency, and S1/S2/S3 percentages.
2. Change one setting. E.g., bump brake gamma from 1.0 → 2.0.
3. Drive another 10 laps at the same track.
4. Compare. Did consistency rise? Did the relevant sector move? If yes, keep the change. If no, revert.
5. Repeat. Steering speed next, then linearity, then TC level.

After 5–6 sessions of one-change-per-session experimentation, you've built a setup that fits your hardware and your hands specifically.

DualSense vs Xbox controller

• DualSense (PS5). Adaptive triggers can be enabled in ACC for haptic-feedback braking — physically resistive triggers that simulate brake pressure. Some drivers find this useful for threshold feel; others find it fatiguing. Try both.
• Xbox Series X|S. No adaptive triggers, but impulse-trigger rumble can simulate ABS engagement (vibration when ABS fires). Worth enabling.

Both work. The control of ACC's physics doesn't favour one over the other; the comfort and tactile feedback differ.

GT3 starting points

A reasonable starting point for a competent controller player on a GT3 car:

• Steering speed: 50
• Steering gamma: 1.5
• Steering deadzone: 5%
• Brake gamma: 2.5
• Brake deadzone: 3%
• Throttle gamma: 1.5
• Throttle deadzone: 3%
• TC: 4 (start), 3 (when comfortable)
• ABS: 3
• Stability: 0

These are starting points, not gospel. Tune from here using the change protocol above.
