Why isn't rust using all of my cpu and gpu?

Specs: (4060 ti, ryzen 5 7600, 32gb of ddr5 ram, 2tb ssd)
I built my pc a few months ago and finally got my graphics card the other day. I'm currently playing rust but the performance doesn't feel great sometimes dropping down to 90s inside busy places like outpost which I feel like shouldn't happen with a 4060 ti. So I turned on RivaTuner and noticed that my gpu and cpu usage is pretty low, sometimes its only using 20% - 30%. Why is this?

because a CPU is not a GPU or otherwise everyone would buy a threadripper.
Rust is using just 4 threads if i remember correctly.

Sorry, I'm not sure what you mean. I know a cpu isn't a gpu.

Not all games have good engines.

Big difference from Haswell (2013 = rust) to a modern AMD 7600X.

Looks like time for a higher resolution monitor

It's a 2013 game so if run on modern hardware it usually run that way. 90s on busier places is still good to be honest. You can force in nvidia control panel to 'Prefer maximum performance' if you wanted to

You have 160 FPS so who cares?

the OSD you are using is counting cpu as a whole. So you won't see 100% useage unless game can use all process cores at max. without knowing cpu you got and specs just say a ryzen 7700x that is 8 cores. if 1 core is 100% load then all you will see on that OSD is ~12%.

You are using 3 CPU cores at almost 100%. Not bad. You can't ask for a lot of CPU usage out of an old game designed for CPUs which existed at the time. They didn't waste time optimizing for many CPU threads for CPUs that didn't exist.
GPU usage? Meh. Probably a game engine limitation too. I wouldn't be surprised if it was a game engine limitation because it is CPU bottlenecked by not being able to use more than half of your CPU. 158 FPS is more than enough. They probably never even considered optimizing for and trying to achieve what wasn't achievable at the time. How would they predict and solve a limitation that they had no way of knowing even exists? I wouldn't worry.
