Question GPU under utilization issues

[RMCC3]

I am trying to find a solution for a buddy that bought a brand new Asus ROG Zephyrus G16 GU605MI laptop. We are trying to play 7 days to die but he can get better than 20FPS with even the lowest graphic settings. 7dtd does not need much for graphics so it isn't making sense to either of us. The CPU is only running at 3-4% and GPU at 30-40%. From what I have experienced, on a desktop, GPU should run in the 99% when gaming. Is this not the case in laptops? is there anything he can safely do to improve in game performance? Seems odd that a brand new 2024 gaming laptop is struggling so much with a game that has low requirements.
