Paul, have you tried deleting the control.cfg file in your player folder? When you start GPL, another control.cfg will be created.
But as your G25 is de-calibrating while you are driving (or hitting something) it could rather be wheel and not GPL or PC related.
This guy here reports that a cable that was connected to the circuit board was loose on his Logitech G25. After fixing it it was fine again.
See (it is in German): https://forum.virtua...-Dekalibrierung
I'd like to talk about the problem:
After some laps (LFS, rF, ...) of driving the calibration of my steering wheel shifted, funny enough always to the right. Happened especially when counter-steering. If I steered the steering wheel to the right with a fast movement, with a lot of power and high FF, this effect could be adjusted.
Because you can hardly break a broken steering wheel: Screw on.
In other words, the hood must be removed. Loosen the lower screws and screw down the steering wheel and the shift paddles in front. Otherwise the hood will not go down.
If you have the hood at the bottom you can see two motors in front of you. One of them - my left one - has a black cover with connected cable at the back. Under this hood sits a small circuit board with an optical angular momentum sensor. Similar to an old mouse with a ball.
Per board, and/or their attachment at the engine, was loose with me.
You could see it clearly when you wiggled the black cover.
You pull - with a force, no fear - the black cap and before the cable (6-pole), not the power cables! - from the motor. Then tighten the two screws in the direction of the motor, I have some curls on it, the cap on it again, the cable on it again.
Assemble everything and DRIVE!
Do again wonderfully and drive like new. Ole Ole!

Use a translator or you might also find infos in English regarding your problem on google.
