Question 2070 low usage

[Headchog]

I have a 2070 and ryzen 5 2600 and the usage on fortnite is low. I cant break 144 fps on low settings on fortnite and the usage stays at 40-60%. I have dual channel 3200mhz 16gb ram. Anti aliasing also barely works on all games and it looks disgusting. Im considering 1440p. Would love some help

The cpu usage is normally around 30-50%. My psu is a semi modular cooler master masterwatt 550w bronze rated. My gpu temperature never exceeds 70 under full load and this is my first system built so I haven't had any gpus before this
