Optimize Rust FPS

I'm experiencing extremely low FPS (3 FPS) while playing Rust despite having a high-speed 1000 Mbps internet connection. I need help to optimize my game performance.

My system specs:
- 32GB DDR4 RAM
- Intel Core i3-10105 CPU @ 3.70GHz (4 cores, 8 logical processors)

I've already tried some troubleshooting steps, including updating graphics drivers, lowering game settings, and checking for system malware.

Ideal skills and experience:
- Expertise in FPS optimization for Rust
- Strong knowledge of system performance tuning
- Experience with similar hardware setups

Looking for someone who can effectively diagnose and resolve the issue to improve my gaming experience.
