[PC] Driving problem Forza Horizon 4

Hello,

As you can read in the title, I have a problem with driving.
I had played the demo a few months ago and no worries but then when I start the game, you know the very beginning with the McLaren in the fall, I roll everything goes well but when I want to shoot, instead that the car turns slowly as I would like to follow
the plot and well it is locked in the scenery, as if someone was playing at the same time as me, I do not understand, yet I have not touched any option in the gameplay or so when I want to turn the car does not respond, I have this problem with this game.

This problem I have often in play, I have already made a reinstallation but still the same problem.
I play with the keyboard.

Opinions ?

:)
