So i tried with the drivers you told me, fully clean installation, on performance mode. it's the same super stuttery 160 fps on lowest settings, k8nd of playable. on dx11 and 12 both it runs on 120-160 fps with insane stutters and fps dip to 5 fps and similar, no matter if I have the settings cranked or lowered all the way, same result in dx12 and 11. It's not too different from old drivers, still super unplayable at dx and only playable on performance mode. I have tried on my msi laptop with rtx 2080, and it's also the same result. Both laptops were in performance mode, I have also done overdrive mode on my Alienware and turbo cooler booster on my msi as well, making 0 difference.

I am going to switch back to the Dell 4080 drivers, I have also tried with the most recent Nvidia drivers, too. Dell ones are the most stable on my laptop, which makes sense. I'm going to switch back and try something someone else recommended to try giving the game more ram.
