Major Performance problems in Rust

[matty11123]

So I used to play with a potato gpu then I got myself an rx 580 4gb oc armor gpu and thought that I would be able to play with decent frames but that is not the case. From what I understand my cpu could be bottlenecking the gpu and according to amd my cpu does not meet the minimum requirements for rust. I have been monitoring my gpu usage and cpu usage and I have noticed my gpu usage spikes rapidly while playing from 100 to 0 to 40 then to 100 and does all random amounts. I am not sure if this is normal and I only get about 40 to 50 frames if im lucky on the lowest settings in rust with this gpu and I play on 1280x720 resolution.

 

Specs:

 

Intel xeon e3 1245 v1
Rx 580 armor 4gb
14 gb ddr3 ram

 

I really dont mind if I can get a solid 60 to 70 and I know this card is capable of it even at 1080p. I just dont get how if it is a cpu bottleneck how my cpu is almost not used at all while playing. Any help would be much appreciated. I would also like to know if the game will have any difference in performance other than loading times if I load it on a ssd as my ssd is coming soon but I currently only have a sshd

I think your being CPU bottlenecked but im not 100% sure. It looks like a old CPU that cant handle the game. I recommend you upgrade to an i5-10600KF or a Ryzen 5 3600.

Yeah I am planning on upgrading to a ryzen 5 3600 but to do that I obviously need a new motherboard and then new ram but sadly I do not have the money for that right now so I am just wondering if there is anything I am doing wrong or anything that may be wrong with my system that I could potentially fix in the mean time.

I remember another LTT user was reporting performance issues with Rust.

They were using a Ryzen 2700X (note, 8-core 16-thread CPU).

 

Further digging around, because Rust uses the Unity 5 engine, it only uses 2-cores (I'm assuming 2-cores 4-threads ...but don't quote me) at a single given time.

It cannot make use of the extra cores available.

 

Your Xeon E3 1245 V1 is based on the Sandy Bridge microarchitecture (i.e. Intel Core-i 2000 series)

Rust's system requirements is an Intel Core i7-3770, which is Ivy Bridge microarchitecture.

Plus, you are running a server tier CPU.

I can see why the game is saying / assuming you don't meet minimum requirements.

 

Considering the damn game can't use more cores, the only way to get more FPS, I guess, is higher IPC, and raw CPU clock speed.

Considering your Xeon is Sandy Bridge era, and with a Base Clock of 3.3 GHz, and max Turbo Boost of up to 3.7 GHz .... ehhh...

Ok yeah I see that the cpu may not be the best but I still dont understand why my fps is so low even on really low resolutions and how the gpu has like extremely weird usage patterns unless that has to do with the cpu bottleneck too.

The lower the resolution, the LESS GPU reliant, and the CPU's performance shows even more.

So-called more "CPU dependent" at lower resolutions.

Oh ok thank you I have tried putting it up to the max resolution of my monitor which is 1366x768 and it may be better after installing msi afterburner which is strange as I have done nothing in msi afterburner but on radeon panel. I have a slight overclock but thank you for all the help. I see now there is pretty much nothing I can do but upgrade my cpu
