Severe Force Feedback issue after update – Fanatec CSL DD

Hello,

I would like to report a serious Force Feedback issue that started after the latest F1 25 update.

Hardware:

Fanatec CSL DD 8 Nm

Fanatec ClubSport / Formula steering wheel

Steam Input disabled

Problem:

The wheel initially works correctly. However, after changing sessions — for example, going from Qualifying to Race — the Force Feedback can become completely unstable.

When accelerating out of a corner and progressively straightening the steering wheel, instead of returning smoothly towards the centre, the wheel starts making sudden left/right movements. This makes it extremely difficult or impossible to control the car.

More seriously, on some occasions when I pause the game, the wheel continues rotating by itself towards one side until it reaches the physical steering limit. Once it reaches the limit, the CSL DD continues applying force in that direction, as if the FFB command were stuck.

Reproduction pattern:

Start a session with the CSL DD normally connected.

Force Feedback initially works correctly.

Finish/change session (for example Qualifying → Race).

In the new session, FFB becomes unstable and the wheel can oscillate aggressively from left to right.

In some cases, pausing the game results in the wheel rotating towards the steering limit and continuing to apply force against it.

Without closing F1 25 or restarting the PC, I switch OFF only the CSL DD using its power button.

Wait approximately 5 seconds.

Switch the CSL DD back ON.

Force Feedback returns to normal or near-normal operation.

I have reproduced the problem multiple times, particularly during session transitions.

The fact that power-cycling only the wheelbase restores normal behaviour while the game remains running strongly suggests that the problem is related to the FFB state/initialisation when F1 25 transitions between sessions.

I have also disabled Steam Input and the issue still occurs.

Current relevant settings:

CSL DD: 8 Nm

FFB Strength: 100%

Natural Damper (NDP): 50%

Natural Friction (NFR): OFF

Natural Inertia (NIN): OFF

INT: 11

FEI: 100

FOR: 100%

SPR: 100%

DPR: 100%

In-game FFB strength: 75

This issue should please be investigated with high priority. On a Direct Drive wheelbase, unexpected full-force steering movement is not only a gameplay issue; it can also present a potential safety risk to the user's hands/wrists.

Please specifically test Fanatec CSL DD → session transition → Qualifying to Race, without restarting the wheelbase between sessions.

I can provide additional information, logs, video recordings or perform further reproduction tests if required.

Thank you.
