I usually get around 220 - 240 fps when i play valorant but when i have valorant open my fps dropped to 60-90 and when i record with it i only get around 60 fps
im using 2 monitors, both of them are 240hz
my spec is rtx 3060 i7 10th gen 16gb ram
i tried using display capture and game capture. both of them makes my fps drop
having streamlab obs open makes my frames drop as well.

Alsoi set my base res and other resolution to my monitor resolution ( 1080p) but streamlabs's recoding thingy is at 1135p. how can i fix that ?
