Question Is there something wrong with my graphic card?

I’ve built my first PC 3 months ago and I now I am wondering if there are any problems with it after there was a massive drop in FPS in game destiny 2. After I restarted PC the problem seemed to go away, however I’ve asked a friend for an advice. We have tried several things such as scanning for viruses, but nothing showed up. When I launched the game after the restart, I saw that the FPS stayed at around 45-55 on the Ultra settings, while my friend’s was around 100. My components are better than his thus this what made me wonder that there is a problem.

Sorry, wrong memory, I though you talked about the VRAM.
