FPS drop


When i play Forza horizon 4, first 5-10 mins everything is normal and i have stable 60 fps (settings High/Ultra) after those 5-10 mins fps drops to 30, even in menu. This all started 2 days ago, before that i played on stable 60 fps and everything was fine. I dont know what to do.

I updated drivers, windows, i reinstalled the game and nothing helps.

Hard drive is working fine, and pc is only about 6 months old.

I have Dell xps 15 9500

My specs:

- i7-10750H
GTX 1650 Ti
16 gb RAM
