Fps Drop to 60 and gpu is not using

Hello Dear EA

in the new split second split of season 2 i start playing after update and my fps is droping to 60 or 70 from 240 

i got 12900k with 3060 12 g i always had 240 fps fix and when i move my screen 180 degree my fps goes to 240 and when i move 180 degree again fps drops to 60 and 70 

i reinstalled my nvidia driver 

update my bios update everything change my windows verify my game files but its still fps drop and gpu ussage is 30% or 40% when fps is drop but when i move my screen 180 degree it back to 100% usage and fps is 240 fix this bug is just for apex legends new split please fix it
