Where is my bottleneck on rust?

Envy78 · 2 Jun 2021 at 15:18

Hi I’ve been playing rust and I’ve heard it’s a very CPU intensive game. My GPU is always on 100% and my cpu is usually around 30% though? Not sure what I would need to upgrade to be able to get better FPS. Any replies would be appreciated. Thanks.

I would start by posting your full PC spec and gaming resolution.

Looking at that tho surely your bottleneck is the GPU as its pinned at 100% all the time and the CPU is only at 30%.

Having a quick look online the recommended hardware requirements are

CPU: Intel Core i7-4690K / AMD Ryzen 5 1600
CPU SPEED: Info
RAM: 16 GB
OS: Windows 10 64bit
VIDEO CARD: GTX 980 / AMD R9 Fury
PIXEL SHADER: 5.1
VERTEX SHADER: 5.1
FREE DISK SPACE: 12 GB
DEDICATED VIDEO RAM: 4096 MB

I use 1080p and I have an rx580 (8gb), Ryzen 7 1800x overclocked to 4ghz, 3200mghz ddr4 16gb of ram. Would you have any recommendations for a new gpu then? Thanks

I do not know much about rust but looking at this video he has the same low cpu usage and maxed out gpu.

I am unsure if this is still the case but the game maybe limited to 4 core max, again this was mentioned in another video

what fps are you getting in the game?

I get about the same as the guy in the video (60-70 usually) just wondering what I would need to upgrade to get more frames. Thanks again

If your GPU is maxed out then the bottleneck is your GPU. Get a more powerful GPU.

Rust world is massive you need lots of ram and vram.

Issue is at the moment finding a new gpu for a decent price is near on impossible!
