Unreal Engine Games not running off GPU

So any Unreal engine game, Helldivers 2, CoDMW, and this random demo that uses Unreal Engine 5, called If Sun Sets… None of these games wants to run on my GPU but puts all the load on my CPU.

The bigger the game like CoD, it puts up to like 90% CPU and 2% GPU and it gets choppy and ■■■■■■.

Any tech guys know whats up? And there’s no integrated graphics. Its custom built PC. And the processor is AMD Ryzen 7 5800x. 3070ti GPU. X570 Aorus Elite mother board. Been lookin all over Google, found some other people with similar issues, but cant figure it out for the life of me.

All the other non Unreal engine games, like Apex, OW2, they all put like 60% load on GPU and 30% on my CPU.
