Now it is clear. Thanks for the answer!
I don't use it at all, so I didn't notice.
The fact is that due to low performance, I have to turn off the monitor, but when the turn signal is turned on, it turns on again and my FPS drops.
Wish I can turn this off...
I also really disliked the mouse steering sensitivity setting
The bus became difficult to control when using the mouse as a steering wheel.
Tomorrow I'll try driving with the Logitech Driving Force GT.
