Can the sensitivity of rotating the lens with the mouse be lowered? Can you help? thx

I can't drive properly and need immediate attention.

The music / BGM was all broken when I played on Steam Deck. Some broken noise was playing and even I turned the in-game music volume slider to leftmost, the noise still kept on playing. Also the frame rate dropped a lot of times, despite the relatively simple graphics of this game. Some part has good fps around 60 which was all smooth though....

i have not the game but would like too can someone tell me if there is a way to disable those shaders?

Can the camera be moved with the mouse?
