i have an rtx 2070 super paired with the ryzen 5 3600. while playing GTA V i noticed that i only get a maximum of 4% gpu load, it doesnt go beyond that, but on other games like csgo,valorant it can go up to 50% and it doesnt go beyond that aswell. shouldnt gpu's go up to 90% load on games?? it would be great if you guys can help me out since its my first pc build.
 
full system spec? include make and model of the psu
what do you use to see the gpu usage?
cpu/gpu temp and usage during the game?

amd ryzen 5 3600
msi geforce rtx 2070 super ventus gp
t force night hawk 3200mhz ddr4 (32gb)
msi b450 tomahawk max motherboard
x63 aio cooler nzxt
adata ssd rgb 1tb
corsair rm650 psu

gpu and cpu temp
stays around 50-60

i use nzxt cam to monitor cpu and gpu usage
