Very bad FPS just for this game on powerful laptop

So, the title can serve as a TLDR.

I have a 5900HX + RTX 3080 (Strix Scar 15).

I have set both windows settings and nvidia settings to run the game on dedicated GPU. It even shows up on the processes utilizing GPU.

But, I still get 601 in the ranked benchmark test. Unacceptable.

What is happening ??

Weird thing is, when I open task manager, and look at the 3080 tab, is see 0% 3D usage, but, significant usage of "dedicated GPU memory usage".
