First time playing this game.

So why are the leaves stuck in air without moving?
Is it a glitch?
I have a nvidia rtx 4060 on my windows 11 24h2.
Do i need to install anything extra for it?
Because i am using nvidia drivers for my graphic card 572.60.
And using an advanced launcher mod and i turned the physx to normal.
The game didn't warn me anything about missing a physx driver.
Edit think i needed the legacy physx drivers to make it work.
Since i just tried and it works i think.
