Doesn't load videocard (Rust)

low fps gtx 1060 3gb / not loaded video card
Rust loads the graphics card by 20% at low settings and produces 50-70fps
At high settings, the video card is loaded by 50-70% and 50-65 fps

Processor xeon e5-1650 - 3.2 gigahertz ( boost 3.5) (6 cores + multithreading)
Graphics Card gtx 3gb 1650
rm 32gb

In other games, everything works stably (the problem is not in the drivers)

The processor and motherboard are all patched and all the cores are open

What do you think is the problem in optimization, and what to do in this case?
