I was an early buyer of the game when it just was on Ubisoft and love every second of it. Recently I’ve had problems with my PCs gpu and am unable to play it on that and ubisoft launcher doesn’t work well on my steam deck. So it’s sadly been awhile since playing it.
I got hooked on Steep and i think that they kept the feel of snowboarding pretty similar to that.
Consider reinstalling it. Delete all settings and what not. Possibly reset your entire system if need be.
These are not common problems with this collection of games.
