Drop FPS in Clubs

When I play in clubs with friends my FPS drops акщь 120 to 10-15. The first match everything can be great, in the second match the FPS drops to 10 and does not increase, sometimes it was that we played for 6-7 hours and everything was fine, and sometimes from the first match 10 FPS. I tried to optimize the game through Geforce Experience, I also reinstalled the game several times and nothing helps.
Now every match with 15 FPS and nothing helps
There is no pattern.
