Problem with low frames per second on a high-end machine
Problem with low frames per second on a high-end machine
I have been playing Rust for about 3,5k hours and it hasn't worked smoothly, even after replacing all parts on my computer, the game still runs at 45 fps on a high-end machine.
I've tried everything I can think of and don’t know who else to consult, so I hope you can assist me.
System details:
Motherboard: PRIME B460M-A R2.0
CPU: 11th Gen Intel® Core™ i5-11400F
RAM: 32GBx4 (2x3200mhz/1x2333mhz/1x2666mhz) No XMP
Storage: HDD WB 1TB / SSD SD 240GB
GPU: NVIDIA GeForce GTX 1660 Ti
Operating System: Windows 10
I never managed to get Rust to run smoothly above 75 fps, I've tested all graphics settings, resolutions, multiple RAMs, CPUs and GPUs, but I still have no idea what else to try.
Initially, it's not a high-end machine; it lacks a strong GPU. Your RAM setup seems mixed, likely running at 2133MHz with a single channel, which results in poor performance. Consider using just the 3200MHz dual-channel option with XMP enabled. Windows and games should run smoothly on an SSD.
The GPU is a bit insufficient, but the RAM setup concerns me. You have two incompatible sticks, which could mean the whole RAM system is operating in single-channel mode, reducing your overall bandwidth. In fact, your speed could improve just by swapping out the mismatched ones.
Running various DIMMs together isn't optimal for peak performance. The specification of 32GBx4 suggests either four 32GB modules adding up to 128GB or four 8GB modules totaling 32GB. Even if each module is only 8GB, removing the slower ones is advisable. Use the two faster modules in the suggested slots and attempt XMP overclocking to reach speeds around 3200MT/s.
The recommended setup for Rust appears modest, but the older i7-4690K offers a base clock of 4.0GHz while the i5-11400F starts at 3.2GHz, though it can increase to 4.4GHz as a single core.

The system should support a 64-bit processor and operating system. Preferred OS is Windows 10 64bit. Processor options include Intel Core i7-4690K or AMD Ryzen 5 1600. Memory requirement is 16GB RAM. Graphics options are GTX 980 or AMD R9 Fury, with DirectX version 12. Network connection should be broadband internet. Storage space of 20GB is available.
It's strongly advised to use an SSD. According to TechPowerUp slides, the i5-11400F's turbo frequency drops significantly under heavy load. Removing the 65W power limit can push the turbo up to 4200MHz, exceeding the recommended spec. A quality cooler is essential for handling increased heat.
Combining XMP overclocked RAM with a higher power limit on the CPU may slightly enhance performance in Rust. For noticeable gains, consider replacing the mid-range i5-11400F with a high-end CPU such as the 125W i9-11900KF. Upgrading to a GTX 3050 or better GPU would also be beneficial, particularly for more demanding games. A "high-end PC" for gaming could involve an i9-13900K or 14900K paired with an RTX 4080 or 4090, though this might be excessive for Rust and is only necessary for power-hungry titles.
