Frame Rate dropping to 20-40fps when I normally get 165

frame rate stays miserably low (20-45) ,gpu utilization temperature and cpu utilization all measure extremely low (10-20% utilization), low network latency, yet frame rate not going back to 165.

eventually mid game I try swapping display resolution and nothing happens. then later I try again and it somehow just starts working perfectly at 165 fps. Then the very next game back to 20 frames

Normally maintained 165 for 3 years while playing, but in the last 3-6 months it has been happening continuously.

If it were just my computer it would be one thing, but my brother just build a new computer and has the exact same problem and can’t play either.

does OW just not work with AMD graphics cards or something? or is some new option changed things? i haven’t made any changes to my system other than updating amd graphics drivers.

I am forced to play other stuff because the game just cannot maintain frame rate

How about cleaning up your current GPU driver and installing an older version? If your brother is experiencing the same situation, there must be a common reason between your PC and his.
