I been playing rust for 3,5k hs and i never got the game running fine, i've replaced every component on my pc and the game still goes at 45 fps on a high end pc.

I tried everything i can think of and i dont know who else to ask so i hope u can help me.

Specs:


Motherboard: PRIME B460M-A R2.0

Cpu: 11th Gen Intel(R) Core(TM) i5-11400F

Ram: 32GBx4 (2x3200mhz/1x2333mhz/1x2666mhz) No XMP

Storage: HDD WB 1TB / SSD SD 240GB

GPU: NVIDIA GeForce GTX 1660 Ti

SO: Windows 10

I never got Rust to run over 75 fps consistently, i tried every graphics config, every resolution, multiple rams, cpus, and gpus, i dont know what else to do.

To start with, it's not "high end computer", it's specially lacking on GPU side. Also your RAM is a mix that's most probably running at 2133MHz at single channel and so with dismal performance. You should try with just that pair of 3200MHz in dual channel and XMP on. Windows and game on SSD of course.
 
The GPU is a tad lacking, but the RAM configuration worries me. You have two mismatched sticks, so there's a danger the entire RAM subsystem is running in single-channel mode, HALVING your total bandwidth. Honestly, your performance might go up by simply removing the mismatched sticks.

Running a motley assortment of different DIMMs is not a good idea for maximum performance.

You quote 32GBx4. Does that mean you have four 32GB modules totalling 128GB RAM, or four 8GB modules totalling 32GB RAM?

Even if each module is only 8GB, ditch the two slower modules. Keep the two faster modules, place them in the recommended slots (A2/B2?) and try XMP overclocking up to 3200MT/s.

Recommended system configuration for Rust seem quite low, but the older i7-4690K has a base clock rate of 4.0GHz and your i5-11400F starts much lower at 3.2GHz, although it does boost up to 4.4GHz, albeit single core only :-

Recommended:
  • Requires a 64-bit processor and operating system
  • OS: Windows 10 64bit
  • Processor: Intel Core i7-4690K / AMD Ryzen 5 1600
  • Memory: 16 GB RAM
  • Graphics: GTX 980 / AMD R9 Fury
  • DirectX: Version 12
  • Network: Broadband Internet connection
  • Storage: 20 GB available space
  • Additional Notes: SSD is highly recommended.

If you look at these slides from TechPowerUp, they shows your 11400F's turbo frequency drop well below 4GHz when heavily loaded.

However, if you remove the 65W power limit on your 11400F, you can boost the turbo frequency up to 4200MHz, i.e. slightly above the recommended spec. You will of course need a good cooler to cope with the extra power dissipated in the CPU.

A combination of XMP overclocked RAM and lifting the 65W power limit on your CPU, should improve the performance in Rust slightly.

If you want to see a significant improvement, ditch the mid-range i5-11400F and fit a high-end CPU like the 125W i9-11900KF. I'd also consider changing the GPU to a GTX 3050 or higher, especially if you play more hardware intensive games.

I think a "high end PC" for gaming might include an i9-13900K or 14900K plus an RTX 4080 or 4090 GPU. Complete overkill for Rust, but some games need a lot more power.

Got my solution in another forum, cpu was overheating cos the stock thermal paste on the cpu cooler wasnt making good contact, causing thermal throttling
