my fps is capped to at least 35 - 45 fps

Yesterday everything was normal, my fps was at 120, but when I opened the game today, my fps dropped to around 40 all the time. No matter how I adjusted or changed the settings, the fps didn't change.
I've tried repairing the game files and reinstalling the graphics card drivers. But these still don't help.
I try Dx12 and Vulkan it still doesn't work, Dx11 fps swings 15 - 100 all time can't play with it.
restart pc nothing has changed.
this happens on every map of the game.
