New Ibuypower pc runs horrible

I just bought an ibuypower pc recently with RTX 4060 And Amd Ryzen 7 5700, 16 gb. And the thing runs horrible I cannot play anything on it. Marvel Rivals For example runs my GPU % constantly above 90%. Fps during any time of actual gameplay is below 35. Drivers are updated. And my gpu wattage shows 0 as well as fan speeds. What do I do?
