game fps capped at 60fps

recently my games verison{1.21.4} fps is capped at 60fps i tried to turn off vsync it didn't work seems like the game can only can get 60fps even though i would get 100+ fps with out any mods. and in older versions.
i lowered my resolution graphics has been minimal still capped at 60fps its been more than 16 days since this problem..
