Question Micro stutters on new PC diagnosis

[paultheoct0pus]

I am experiencing micro stutters. See graphs in video below, this occurs in all games…

Build:
Thermalright Phantom Spirit 120 SE 66.17 CFM CPU Cooler
MSI PRO B650-P WIFI ATX AM5 Motherboard
AMD Ryzen 7 7800X3D 4.2 GHz 8-Core Processor
G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL36 Memory
Samsung 980 Pro 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
NVIDIA Founders Edition GeForce RTX 4070 12 GB Video Card
MSI A1000G PCIE5 1000 W 80+ Gold Certified Fully Modular ATX Power Supply

Temperatures seem fine, ran bench marks and while not amazing, nothing shows in here

Things I've tried:
Closing everything running on PC beside game
Updating GPU driver
Updating BIOS
Updating chipsets
Enabling XMP
Monitoring temps while this occurs, occurs even at low temps (60C, goes up to 80C but still sees this lag on 60C)
Power mode to High Perf

I really do not want to have to gut the PC and return the CPU as it was a bundle from microcenter, so i might need to disassemble the entire thing if I were to. I also no longer have the boxes (i know im stupid) so it would really be a huge pain.

Does anybody have any ideas on what I can try?

Hey there,

Did you clear CMOS after the bios update?

Are you OC'ing anything? Uninstall the GPU driver with DDU (safe mode). Reinstall the driver fresh.

Are you using any software to monitor FPS, like MSI Afterburner OSD? Or any OSD for that matter. If so, run without.

Have you tried changing the polling rate on the mouse? Is there proprietary mouse software like iCUE, or Asus Armoury Crate?

Try using only mouse and keyboard as attached usb devices. Then try with any other mouse/keyboard.

What power profile are you running?

I would hardly call those stutters... you are getting like 0.5-2ms "spikes" in that video. Usually for a stutter to be felt or ever be able to be seen, they would have to be like 5-10ms spikes. The largest "Spike" I saw in that video was about 3ms.

I also notice that you are on uncapped FPS, what is the refresh rate and resolution of your monitor? I would set an FPS cap to either the exact refresh rate of the monitor or 1 higher and see if that helps. Is v-sync on? What game is this?

Your CPU should never hit the 0th percentile, not even in that crappy benchmark, something is definitely going on there...

Enabling XMP

No EXPO profiles on the RAM?

It actually seems like it was GeForce Experience OSD FPS counter that was causing it. Turned it off and now its gone

So what would you classify it as? I didn't know either how to describe it. But it is definitely noticeable in competitive games where you need stable 144+ fps

You make a good point. But I also ran some OCCT stuff and saw no CPU issues. What do you suggest I look into regarding why it's performing at 0th percentile? (I reran and it was at 14 pctile). Note I also did have a ton of applications open (spotify, chrome, VMWare horizon) while running the benchmark, but looking at my past runs too they are all very low pctile so not sure if that matters.

I don't know what to classify them, though I can see a corresponding, albeit, super tiny hitch in the recording to accompany the "stutters." Nano-hitch? No, lets just call them microstutters I guess.

I am glad that you figured it out. Many OSDs like geforce experience, steam overlay, et cetera can cause little issues like this, but as you learned, it had very little to do with your hardware.

I would get cinebench and run a multi and single threaded run after a clean boot, this will tell you via a score how your processor is generally running. It is easy to compare these scores with others as the test is standardized without random elements. Post back the scores here and we can compare them with expected results from other 7800X3D CPUs.

Yup, this happens frequently. I often get bogged down in game, with Afterburner OSD, checking metrics while I game. Not only is it a distraction from actually enjoying the game, but they do/can cause stutters.

Sorry for the late reply, was away for the holidays.

I ran cinebench R24 and saw the following scores on a mostly clean run (didn't do a clean boot but closed everything and left just it running).

GPU: 16758
CPU Multi Core: 1042
CPU Single Core: 110

Online scores I found from CPU monkey / dropandrender
GPU: 18700
7800x3D Multi Core: 1115
Single Core: 107


GPU kind of concerns me. What do you think?

Hey @helper800 any chance you saw my previous response? Warranty ends on 15th of this month so would like to know what you think!

What case is in your build? It could be the difference between your GPU and online have lower scores because of a lower boost speed. Having good airflow can help. Don't pay to much heed to online scores. You don't know if they have OC'ed components or not.

I would say that you are fine. The differences in score between yor GPU and the online scores very likely comes down to higher power limits / OCing on the cards from online. The only other thing that it could be is that certain components on your graphics card are overheating, and not necessarily the GPU core temp, which can hold back your clock speeds from boosting higher. The hottest reported temperature sensor on your graphics card is what will give you a telltale sign on this. This metric is usually shown and reported by HWinfo in sensors mode.
