computer degrading framerate

[kalizy12]

Hi, so i have been getting a ton of issues with my pc lately. I started playing r6 siege on the map house, the framerate at the time was high enough not to feel laggy but after some matches afterward i start getting low framerate that i shouldn't be getting on those maps or any of them at all like from a good solid 50 to 20ish fps and stays constant, even in the main menu. I've already tried troubleshooting with ubisoft and nothing worked, from clean boots to reinstalling the drivers the problem still persists, degrading fps with the course of time. the dxdiag and msinfo were taken just now

 

msinfo.nfo

edit: cpu temp is always below 40 so it wasnt throttling
