(RUST) PC not using all GPU, CPU and Ram available - RTX 2080 TI with I9-9900k

[kxrbys]

Hey all,

Experiencing low FPS performance across most games but especially across Rust which I play most frequently and I feel there might be something wrong with my build that is preventing it from performing well.

Normally achieve 70-80 FPS in Rust on medium to high settings with the PC performance around 50% usage for the GPU and between 20-30% usage for the CPU. Even if I lower the settings to the worst possible in game I don't achieve any more FPS and the usage stays the same.

I've followed guides where I've changed the power settings, updated drivers etc but these didn't make a difference.

My PC Build:

RTX 2080 TI GPU
Intel I9-9900k CPU
ASUS STRIX X470 F Gaming Motherboard
32GB Ram (Same brand)

Does anyone know what's causing my pc to have low FPS and what I can do to get the most out of my build?

Best,
Kxrbys

What power supply do you have ? Did you try to max out your graphic settings in that game, since it might be a CPU and/or poor game optimization. What other games did you try with that system ?
EDIT: also there is some confusion you have an AM4 motherboard with a Intel CPU that is impossible to run.

What resolution? What CPU/GPU temperatures on load?
Did you try a 3DMark benchmark?

rust is extremely memory intensive and bottlenecks on ram/cache. What is your ram speed at?

Hey Droopy,

Power supply is an Corsair RM750I.

I've tried to max it out by turning the settings to full (Average 70 FPS) and then when it put them on lowest possible I still sit around the 70-80 range. Doesn't seem like editing the settings lower increases the FPS by much.

I understand that the game is badly optimized perhaps based off what other people have said.

Rocket League sits around 60% GPU usage and 30% CPU usage with good frames on max settings, but I guess it's perhaps a bit less intensive.

ASUS STRIX X470 F Gaming Motherboard is the motherboard in my PC, came from a prebuild gaming company so perhaps they have done some sort of work around to make it work?

Hey P4-630,

I have a 49 inch curved Samsung gaming monitor however only run the games on 2560 by 1440 normally in windowed form. I've tried full screen, borderless windowed and windowed but all seem the same.

Not sure how to check the temperatures unfortunately so I'd like to know how to do that?

I've also not used 3dmark before however downloading the demo now to get an understanding of what it is and how it works!

Any suggestions for once I get it?

Hey Phanbuey,

Seems like it's still got spare ram whilst playing to be used.

Any thoughts?

Well. First, you have a AMD Ryzen 3900 12 core not an Intel i9. I have not played the game, but from others say it is not very well optimised. Try maxing out the settings you will probably have the same framerate but with better graphics. Also something is eating your RAM. Try to see what app is using that much RAM. Go to Task Manager > and sort apps by memory usage and post a picture here.

So actually the amount doesn't really matter -- your ram is running at 3000Mhz. if you increase that speed your FPS in rust will increase (and/or change some timings) and your RUST FPS will go up noticeably in all scenarios (even if your low FPS is caused by something else, overclocking ram will give you noticeable jumps from where you're currently at).

Some things to try for rust:
1. Make sure your power settings in windows is set to 'High Performance', then check fps
2. Use HWmonitor (sensors Only) to show temps while gaming (run it in the background), if you throttle / Overheat you will see it there.
3. When in game in rust, if you have Geforce experience turned on you should be able to press ALT+R and that will show you CPU and GPU usage in performance overlay, if the GPU usage is below ~90% then you're bottlenecked on RAM / CPU .

Rust is really not that well optimized but they are trying and if this helps, all i can say is this.

I run my own private server for my friends and myself, i also use the default map size of 4500 and use mods to.

I run the game at 2k with everything pretty much maxed out.
While running the server and the game, it can eat upto 27gig of system ram.
i get around 80fps max with drops to about 55fps and this is running on my 5600x with 32gig of ram at 3800mhz and a nvidia RTX 3060.

I only have about 6 people playing on my server as it's private but when playing on other official or modded servers with many people playing, it can eat up lots of system ram and FPS will get lower due to more entities spawning over time and with more things being built.

Atm my server is using around 4gig of system ram but it's been running for a while and does drop it's usage over time lol but when i first load the server up, it will use 8 or 9gig of system ram for a good few hours before it settles down to haha
