Updated Findings: New Test Method Validates Issue
In Gran Turismo 7 (and Gran Turismo Sport), a severe issue with gas pedal input delay persists across all supported steering wheel and pedal setups. Using a new test method, the problem has been analyzed further, and the results strongly validate that this is a core issue with the game itself, independent of driving conditions such as slope, speed, or other external factors.

Key Symptoms
1. Gas Pedal Delay at Idle and During Driving:
When the gas pedal is released fully, the in-game virtual pedal and engine response lag behind the physical input. The engine RPM drops much slower than expected, disrupting gameplay precision.
2. Temporary Fix with Specific Actions:
When testing with manual transmission and clutch, the issue can be temporarily neutralized by a specific sequence:
Allow the car to stall while in gear and holding the brake.
Restart the engine by gently releasing the clutch and softly pressing the gas pedal.
Immediately shift into neutral after the engine starts.
In this state, the engine RPM responds normally to gas pedal input, and the delay disappears.
3. Issue Returns During Driving:
Once the car begins moving again or the engine RPM is allowed to drop to idle after driving, the problem returns, with the same delayed response.
4. Inability to Feather the Throttle:
Due to the delay, it is impossible to modulate the throttle precisely. This impacts techniques like maintaining light throttle input during cornering or accelerating smoothly out of turns.

New Test Methodology
To demonstrate the issue clearly and isolate it from other potential influences, the following test procedure was developed:
Steps:
1. Controlled Environment:
Use a car with manual transmission and clutch. Perform the test while stationary to eliminate variables like slope, speed, or traction.
2. Testing Gas Pedal Response:
Release the gas pedal fully and observe the delayed drop in RPM.
Compare this behavior with a scenario where the car is stalled and restarted.
3. Temporary Neutralization:
Allow the car to stall while in gear, holding the brake.
Restart the engine by softly applying gas while gently releasing the clutch.
Shift into neutral immediately after the engine starts.
Observe that the RPM responds normally to gas pedal input in this state.
4. Reintroduction of the Issue:
Begin driving normally again. Observe that the delayed gas response returns as soon as the car is in motion or the RPM drops to idle.

Analysis and Insights
1. Core Software Issue:
The temporary fix described above strongly suggests that the problem is rooted in the game’s engine or input processing, rather than hardware or external driving factors.
2. Not Dependent on Driving Conditions:
Critics of the test method have suggested that slope, speed, or other driving conditions might influence gas pedal behavior or throthlle position itself. However, the controlled test environment (stationary vehicle) eliminates these variables.
The problem occurs consistently regardless of driving aids, road incline, or other external factors.
3. Fundamental Gameplay Disruption:
The inability to feather the throttle properly makes precise driving impossible, particularly in scenarios that require delicate throttle control, such as cornering, drifting, or maintaining traction.
4. Inconsistent Simulation Behavior:
The game’s throttle behavior deviates significantly from real-world vehicle mechanics. In real life, gas pedal input always has a direct and immediate impact on engine RPM, whether stationary or moving.

Community Feedback and Evidence
Numerous players on forums like GTPlanet and Reddit have reported similar issues, reinforcing that this is a widespread problem.
Videos demonstrating the delayed gas pedal response are widely available online.
Advanced sim racers and casual players alike have expressed frustration with the inability to achieve realistic throttle control.
Conclusion
The new test method demonstrates conclusively that the gas pedal input delay is a fundamental issue within Gran Turismo 7 and Gran Turismo Sport. The problem is independent of external factors such as slope, speed or throthlle position and significantly disrupts gameplay for all users of steering wheels and pedal setups more important clutch users not race drivers.
Immediate action is required to address this issue, as it undermines the realism and precision expected from a high-fidelity DRIVING simulator.
