My game crushed and i restarted it. But fps dropped to about 5! If i did alt+Tab and alt+Tab to the game again, the fps comes to normal but for few seconds and it drops again. Deleting and reinstalling drivers helped, but only untill the next start of the game and the dropping stuff came back. Everything is fine with my GPU, it works great. I did benchmarks, i played another games. Everything is fine but Destiny 2.
