Question Powerful PC is stuttering ?

[D3470]

​

PC Specs​

GPU: Zotac GEFORCE RTX 4080 SUPER ​

CPU: Ryzen 7800X3D​

Motherboard: MSI MPG B650I, mini-ITX

Case and cooler: Cooler Master NR200P MAX V2​

SSD: WD_BLACK SN850X 4TB
RAM: CORSAIR VENGEANCE DDR5 64GB (2x32GB) DDR5 6000MHz

So the issue that I’m having is that my pc just doesn’t seem to be performing like it should. It gets decent fps but the game just doesn’t look like it’s running properly. On Rainbow 6 siege for example I have tried both high and low graphic options and get in the realm of 400fps, I set an fps cap of 350 and it will hold stable at that with my gpu running at about 85-95% on msi afterburner and cpu at around 65.

Temps are very low for both but for some reason every now and then my fps will drop by 1 or 2 fps but will have a big spike in frame time and stutter, I can’t find out what’s triggering it. I am running expo on my BIOS, and running latest version, but haven’t really tweaked anything in BIOS. I am just at a loss, drivers are all up to date. I’ve tried changing all sorts of graphics. Running highest power plan and highest performance on control panel.

Apex also just runs like trash. I’ve tried every setting on that and it just stutters constantly and looks blurry when I look around. I also occasionally get a different issue on siege where it will jump up to like 99% gpu performance and fps will be around 250 and look like rubbish, seems to happen from tabbing out and then I tab back in after a few minutes on youtube and come back.

Any help would be gladly appreciated as I'm just tired of trying to figure it out.

EDIT: I'm desperate. PLEEEEASE, take pity on my soul

PSU: make, model, wattage, age, condition (original to build, new, used, refurbished)?

Disk drive(s): make, model, capacity, how full?

Games: source(s)?

= = = =

Use Task Manager and Resource Monitor to observe system performance.

Use both tools but only one tool at a time to observe system performance.

Objective simply being to watch for what (if anything) changes when the stutters occur.

You will need to keep the tool window open and observable while gaming.

There are other tools that may prove useful. However, starting with the basics is recommended.

It's the PSU that comes with the NR200P max

• 850W SFX PSU (80 PLUS Gold, ATX 3.0, modular

I have a WD_Black sn770 250gb which I have windows installed onto which has 30gb free.
I keep all my games on the drive mentioned in the original post which has 2.6tb free storage.

I have tried running the game both fullscreen and borderless with windows game mode both enabled and disabled, doesn''t make any difference.

This was a new build back in Sept by myself all brand new parts.

How would you recommend I use each tool whilst gaming? Will I need to play in windowed mode? Or what?

I'll give that a shot and see if I can spot anything whilst I await any update.

Thanks!

Ok. So I think I've figured it out, so even though the total cpu usage is around 70s or 80s % and doesn't really get up to 100% cpu 4 and 5 in resource monitor are much higher and the stutters seems to correlate to one or both of those hitting 100%. I don't know what that means, if it's something I can fix in BIOS or what but that seems to be the cause of the stutter.

I would go straight for DDU and reinstall graphics drivers, then report back.

Did this a few months back and also tried several different specific driver versions which were safe, didn't make any difference. Tried to give it another go but for some reason pc won't boot into safe mode.

Ok, so I have confirmed that it is something to do with cores 4 and 5, I went into task manager and set affinity to all cores except 4 and 5, completely fixed the issue. So the next question is why is that happening? My old 3800x could run the game without overloading cores, is it a BIOS issue? Could it be a faulty cpu? Using all other cores fixed the issue and still kept cpu usage to around 80%. This is where it goes far beyond my understanding of PCs

 

[thestryker]

70-80% CPU usage in any game seems pretty high unless SMT is turned off which it shouldn't be. That would be the first thing to look into a verify that it is just the game doing that and that SMT isn't disabled.

I don't recall if AMD has per core temperature monitoring exposed to the user, but if so that would be something to check (HWiNFO is what I would use here). It would also be worth checking the clock speeds when those cores are loaded as well.

Here is the data of core temps and core clocks and usage over a short gaming period with all cores being used for siege. My fix of setting affinity to all cores except 4 and 5 worked for about a day and has now stopped and is just causing other cores to spike above 100% usage. SMT is set to auto (disabled is only other option I can see).
I did turn gaming boost off and back on, I think this just tries to boost clocks and slightly undervolt safely and just blasts the fans on max, found it was slightly better with it turned on. That's all I can think of, I don't know why on earth my cpu is being used so much. I'm at a loss in all truth.

 

[thestryker]

Seems like your CPU is behaving as expected which leads me to believe it's a problem with Siege. Is it just the game executable with the high CPU usage or are there other things like ubisoft connect related?

I'd definitely suggest trying another game or two before really digging into just Siege, but I'm pretty sure the issue isn't hardware.

I have had the same issue playing apex legends which is the only other game I really play, had no problems from what I can tell on assasins creed or helldivers or hogwarts legacy, but I play those casually on a controller from my bed rather than locked in right in front of the screen. Apex seems to have the same issue with stutters.

Running the game in windowed with task manager open next to it siege is the only thing really using cpu, system and a few other things running at 3% or less. But siege is taking up the bulk.

Here's a video of how I'm testing, you can see the stutters in the bottom left when it dips momentarily and to me that seems as though it correlates with a cpu core topping out.

I have tried various different fps caps, I reduced it to 220 for this, but I find it's the same at 180 ,100, 360 or even around 400, it'll hold stable fps and then just dip by a few fps and stutter or freeze.

Finally had a chance to look at that on a big enough screen and it doesn't look like CPU usage is an issue at all. Individual cores hitting 100% isn't particular a problem it's when all of them are that you add latency to the system.

It would be worth checking system latency using LatencyMon to see if it can flag something in particular.

Are games and the OS on the same drive? Generally that shouldn't be an issue, but we are talking very high frame. rates. Given that you've tried capped frame rates lower I'm not sure this is very likely at all unless you're using a SSD that's too full.

Fullscreen or Borderless generally speaking?

I know you mentioned in the OP tabbing out for something that uses the video card causing worse issues so perhaps kill anything that utilizes the video card and maybe anything with overlays.

Can't really think of anything else right now.

Os is on a separate drive to games, all my games are on a 4tb drive. It's got over 2tb free storage. My os drive has got quite a bit of storage taken up by videos and a massive pagefile (not too sure why I actually set that up).

I have tried fullscreen and borderless, same issue regardless.

I've tried running it with no other tabs open and with my usual ones (spotify, brave, discord) and it makes no difference. I used to run the same settings pretty much on my 2080super build with a 3800x and it ran fine (albeit at much lower fps) so I'm very confused. I would be surprised if I have to close all other tabs to get it to run. I am simply out of my depth here, all I can see is that it seems as though the stutters happen as cores hit 100% and so the cpu is bottlenecking the gpu. The reason for that is beyond my level of understanding.

Not sure if this is the right page for latency mon or not but this was the result on the main page.https://drive.google.com/file/d/1FYyhrWyhjz_1LrAGqYA0JOoYW8kiEOoG/view?usp=sharing

This would be a really stupid problem, but it's not impossible something could be going on with the riser cable. First things first verify that the card is currently running PCIe 4.0 x16 with GPU-Z. I'm fairly certain it is, but doesn't hurt to check. If it is go into your BIOS and switch it to PCIe 3.0 and then see if that changes anything.

You've already done DDU in the past so I don't really think driver installation is the issue.

 

[D3470]

It is in 4.0. I will try running it on 3.0 tomorrow. By the way I really appreciate you taking the time to try and help me find a solution. Thank you!

I went in to BIOS and switched it to 3.0 but when i booted it still said 4.0 on GPU-Z, in any case it made no difference to gameplay. Did you watch that recording? Am I right in saying that it coincides with cpu spikes on the cores? If so what can I do to try and reduce that cpu load? I've tried an fps cap, I've tried running with everything else shut, it is purely rainbow six siege using all that cpu up and I have no idea why.

Do you think it's worth me doing a full pc wipe and a clean install? I'm reaching the point where it's so unplayable across games that I'm thinking about selling it and just buying another pc or building a new one. I might try my local pc specialist if nothing else works.

Lock your FPS a couple frames below your monitor refresh rate and try that.

Locking it in game I assume. I've got it locked at 357 right now (360hz) and it's not improved at all. Same thing at other refresh rates and frame locks

 

[thestryker]

I went in to BIOS and switched it to 3.0 but when i booted it still said 4.0 on GPU-Z

If it still says 4.0 in GPU-Z you didn't get it changed to 3.0 because it polls active system data. While the BIOS manual is light on details I believe the one you need to change is PCI_Ex Gen Switch.

I've sent it off to the local pc specialist to figure out if they can find what's wrong and if not I'll see if it's covered under warranty with amazon, we'll see what happens over the next week.
