Hardware Involved:
Steering wheels and pedals from Logitech, Thrustmaster, and Fanatec.

Overview of the Issue
In Gran Turismo 7 (and previously in Gran Turismo Sport), a critical issue with gas pedal response affects all supported steering wheel and pedal setups. The game exhibits an extreme delay between the physical gas pedal input and its in-game response, which disrupts precision driving and negatively impacts gameplay.
This issue is present across multiple hardware setups, regardless of manufacturer (Logitech, Thrustmaster, or Fanatec), and originates from the game’s input handling.
Key Symptoms:
1. Delayed Virtual Gas Pedal Release:
Rapid release of the physical gas pedal does not result in an equally rapid virtual pedal release. The in-game animation and throttle response lag significantly, causing the engine RPM to drop slower than in real-world driving.
2. Inability to Feather the Throttle:
Due to this delay, it is impossible to smoothly and precisely modulate the throttle (e.g., to keep slight pressure on the gas pedal while driving). This is especially problematic for advanced driving techniques like maintaining balance in high-speed corners or managing traction during acceleration.
3. Universal Occurrence:
The issue is not specific to any single hardware manufacturer. It affects all players using supported steering wheels and pedal setups, including Logitech G29, Thrustmaster T-GT II, and Fanatec GT DD Pro.
4. Impact on Immersion and Control:
The problem is particularly evident in cockpit view and VR gameplay, where the delayed response of the virtual driver’s foot and gas pedal is clearly visible, undermining the immersive experience.

Analysis
1. Game Engine Filtering or Input Smoothing:
The issue appears to stem from built-in input filtering or smoothing within the Gran Turismo engine. While this may be intended to simulate a gradual throttle response, it introduces unrealistic delays that do not reflect real-world vehicle behavior.
2. Functional and Visual Disconnect:
The delayed animation of the virtual driver’s foot and gas pedal might initially seem cosmetic, but testing shows that it directly affects gameplay. The throttle response is also delayed, making precise input impossible.
3. Severe Simulation Inaccuracy:
Real-world driving requires the ability to feather the throttle with finesse, keeping slight pressure on the pedal when necessary. In Gran Turismo, this finesse is impossible due to the exaggerated lag, significantly deviating from real-world driving physics.
4. Driving Aid Independence:
The issue persists even when all driving aids (e.g., traction control, stability control) are turned off, confirming that the problem lies within the game’s core input processing and not in optional settings.

Reproduction Steps
The issue can be consistently reproduced as follows:
1. Connect any supported steering wheel and pedal setup.
2. Start a race and enter cockpit view to observe the virtual gas pedal and driver’s foot animation.
3. Attempt to:
Release the gas pedal rapidly.
Feather the throttle by lightly modulating pedal pressure.
4. Observe the lag between the physical input and the in-game response. Note the inability to maintain consistent, light throttle pressure.

Community Evidence and Feedback
Numerous players on platforms such as GTPlanet and Reddit have reported this issue.
Videos of gameplay clearly demonstrate the delayed response, affecting players across all supported hardware.
Advanced and professional sim racers have highlighted how the inability to feather the throttle significantly hinders the precision required for competitive play.
---
Proposed Solutions
1. Immediate Patch for Input Response:
Introduce an option in the settings menu to disable or customize throttle input filtering.
Provide a slider for gas pedal sensitivity and response time, allowing players to fine-tune the input behavior.
2. Real-Time Input Processing:
Ensure that gas pedal inputs are processed in real-time, with no artificial delay, to match the precision and responsiveness of real-world driving.
3. Animation and Gameplay Synchronization:
Synchronize the virtual driver’s foot and pedal animation with the actual gas pedal input to maintain immersion and visual consistency, especially in VR.
4. Developer Acknowledgment and Transparency:
Polyphony Digital should acknowledge this as a critical issue and provide a roadmap for addressing it in future updates.
---
Conclusion
This issue represents a severe deviation from the realistic driving experience that Gran Turismo aims to simulate. The inability to feather the throttle with finesse and the noticeable delay in gas pedal response significantly impact gameplay quality, especially for competitive players and VR users.
Polyphony Digital must address this issue urgently through a software patch to restore the precision and immersion expected in a high-fidelity racing simulator.
