Poor performance

Hello,
From three days after the system format I have very poor performance in the game. A few days ago on “High” settings I had a 60fps but now on “Low” I can’t even reach 60fps. There is no such problem in other games. What is going on?
Reinstalling the drivers did not help.
pc specs:

cpu: amd fx 8300
gpu: msi geforce gtx 1050ti gaming x
16gb ram
mobo: gigabyte ga-78lmt-s2
the game is on ssd (system disc)
psu: silentiumpc vero l2 500w

also i don’t know why forza is recognising my monitor as 240hz i have 60hz monitor

benchmark on low: Imgur: The magic of the Internet
benchmark on high: Imgur: The magic of the Internet

ok after update problem solved
