Frametime spikes and stuttering after switching to AMD CPU?

[Montelo]

i dont think its faulty hardware and you likely havent fully exhausted all options available to you yet. i think that if you update, optimize your bios, cpu and ram and go with win11 iot ltsc your issue should be gone.

be aware that small caching / first time loading stutter can be quite normal when you load the first game, first map of the day, etc - and these should more or less disappear the longer your gaming sessions becomes.

I updated/Downgraded my Bios before didnt change anything sadly.

Yes i know that some stutters are normal but Stutter/Frametime spikes like this are not normal

Hard to see again but its really annoying

so to clarify - you didnt update the bios - you just downgraded it? or are you saying that you first updated and then downgraded the bios again?

you couldve also taken the risk and make a proper update as well.

so, for example, have you verified that your windows installation really runs in uefi mode? could you post a screenshot and proof that it does?

if i may ask what exactly have you tried from the list of points that i recommended if as you said you already tried everything and it didnt work?

your game will only be more or less smooth and free of stutters if you run some kind of sync, ie. vsync, gsync or free sync as is explained on the blurbuster website - and / or - you did some kind of optimizations - if the regular methods dont seem to fit your issue. its more or less impossible to completely prevent any stuttering from ever occuring. depending on the type of stutter they are natural and not a sign of an issue.

and due to that the clips you posted are good in qualty but too short in duration for us to see and make a proper analysis. please try to record for a prolonged period of time, say 3-5 min or up to 15 / 30 min that shows more of these spikes and point out at what timestamp there are issues.

you can also turn on statistics monitoring for cpu, gpu power draw and / or other stuff in the afterburner osd; the more info thats in the osd the better for us to see and to debug.

but this one random spike in the league clip - which i believe you are referring to and those in the other clips - could be anything and it doesnt necessarily indicate an issue.

and if the game you play runs from the same disk where windows is installed you will be prone to having more of spikes like these which are pretty much normal and more or less unavoidable and naturally present on every pc. there could also be an issue if theres an nvme present that shares the pcie lane with the gpu because in some configuration this can lead to similar issues and so its better to have windows and the game you play each installed on a seperate physical disk.

please go ahead and generate a few different projects for different games in capframex and post the results here and record your gameplay for at least 5 min or better something like 15 min, 30 min or 1 h to be analyzed in capframex and this too will give us better insights into what type of stuttering is going on.

Is CPU fTPM enabled in the bios? It's known to cause stutters and the like. My setup used to have stuttering problems in the past and disabling the fTPM fixed it.

 

[zoulztealer]

No need top optimize BIOS. Just enable XMP/Expo, ReBar/SAM and that's it. A case could maybe be made for SMV, SMT. Maybe.

Bios update can also do worst with some security patch that will make your system lose performance, so I would not recommend to update BIOS blindly.

Please don't OC your CPU and RAM unless you are really passionate about it, OC require time and investment and have to be done the right way. It's not for everyone.

Now, could you please explain in your own words whats the benefits of using Windows LTSC and how it's supposed to solve the stuttering OP is suffering?

cant help you with that - but - xmp profiles can be faulty (meaning either the board or the profile dont translate the values properly; so even if the xmp profile is properly loaded in bios actual readout and actual real world values will be different values that do not equal those stored in the xmp profile) plus an optimized bios runs always better and has better benchmark scores than an unoptimized one and i think everyone is aware of this fact.

and i never said anything about overclocking and i didnt say windows ltsc i said windows 11 iot ltsc so i am not quite sure if you are aware of the difference but - these are not my own words this is from microsoft:

"Windows 11 IoT LTSC is an optimized version of the standard Windows 11 OS, specifically designed for embedded and purpose-built devices. In gaming environments, Windows 11 IoT can drive gaming consoles, interactive gaming terminals, kiosks, and arcade machines."

its like made for gaming specifically. the good thing is it comes with a lot of things removed - which is good for overall system performance, responsiveness / input latency and such as in this case reduction of spike interefering by reducing / eliminating back ground tasks, services, etc, everything thats been removed and disabled and its alot - but all you really need to do to get it to gaming is basically install the xbox app and from there you can install the missing store and other essential things from inside the xbox app settings menu and ms store as well, add a few other things like tpu redist package and thats almost everything. i think ms wanted and intended it to be this way so to make ltsc able to run games with only a few clicks.

https://aka.ms/xboxinstaller

if you only want to game with win11 iot ltsc theres not much to be done different than from what is needed with a regular windows, so basically a few runtimes, framework sdks, steamworks common redistributables, steamworks sdk redist, ue4 engine 64bit redist, directx, gpu drivers, chipset drivers and audio - where sometimes its better if you do not install the two latter, ie. chipset and audio because its not always needed and can cause issues - but on the other hand it may also solve them.

either way what they created with win11 iot ltsc - intended or unintended - is the best windows for gaming i have personally ever experienced and i think that is out there right now and i will never use anything else again than this - or maybe in the future something linux like nobara but for me win11 iot ltsc is simply perfect in every aspect, easyness, performance, fps, input latency, compatibility, stability and everything thats important for gamers and it will improve much more in the coming time as well in the race with linux, ie. updates to the graphic kernel.

and not only does it have super low system requirements - which makes it super snappy on high end systems - it also doesnt require tpm or other things and can basically run on and from everything (iot):

Tested out this Ram Kit still getting stutters, i dont think the Ram is the issue then

I updated the Bios first to the newest Version it was from May 2025 i think, but since it didnt help i tried an older version from 2023 aswell just to check but the same thing happened
I tried things that you listed on that one post.

Like Updating Bios.
Using Low Latency Mode.
Disabling Windows Game mode, Game bar etc etc
the only thing that i havent tried that u told me is that Windows iot ltsc and the NVcleaninstall

If u tell me where and how i can see if Windows is really is in Uefi mode i will send u a screenshot for sure

I will Record a 5 Minute Video tomorrow im gonna post the link here with timestamps

 

[Launcestonian]

Have you tried it with SMT disabled?

 

[iSpeakVeryWell]

xmp profiles can be faulty

It sure can, but I fail to see what it have to do with anything I said in my message you quoted.

plus an optimized bios runs always better and has better benchmark scores than an unoptimized one and i think everyone is aware of this fact.

Better benchmark score doesn't mean a stutter free experience. One can have super high benchmark score and have an horrible gaming experience. Saying "optimized bios" is way too broad. Theire is some specific settings worth investigating, and many settings that will do worst.

and i never said anything about overclocking

optimize your bios, cpu and ram

What do you mean by optimize CPU and RAM then? I thought you meant OC. My bad.

and i never said anything about overclocking and i didnt say windows ltsc i said windows 11 iot ltsc so i am not quite sure if you are aware of the difference

I'm well aware of the difference between the two and I said LTSC because I know that both doesn't help for gaming compared to Home edition and both won't solve the problem OP have.

I see that you are very sold on Windows IoT LTSC, it's totally fine. I've been there too! I'm now using Windows 11 Home edition for my gaming PC. It require less work to bring it game ready and games run better. IMO, there is many reasons to use LTSC/IoT, gaming just isn't one. Home edition is truly the best for a gaming PC.

The following screenshots come from the exact same website you didn't dared to name where you took your screenshot!

My goal is not to fight. In fact, I'm very glad you do your best to help OP fix his problem and I really hope you come to find the solution.

@Montelo, best of luck, I hope you will find a fix real soon!

Edit: I just realized you picked your screenshot straight from Microsoft website. Well... I'm stupid. I thought you took it somewhere else. Sorry about that.

@Montelo Did you check the fTPM setting as mentioned earlier by DR4G00N? I think that's worth following up on.

didnt do that yet i googled how those stutters look like, they come with audio stuttering i dont have that kind of stuttering but i can still give it a try

 

[Montelo]

Here is a 5 minute video on how it looks in CS2

these are the Timestamps for the noticeable Stutter i didnt count any so small microstutter

1:17 2:38 4:08 4:54
1:59 "Big stutter"

Most of the stutters are probably hard to see on Video but you can feel them the only stutter that is easy to see is probably the one at 1:59

Stutters like these are also in League of Legends.

In Baldurs Gate 3 for example the stutters are more Noticeable, i can do a video of it aswell if it would help

that didnt help either really.. i think we are really running out of options

 

[OolongGoat]

Okay.... sooooo have you reinstalled Windows at all? Are you using the same install since making the switch of CPU and Motherboard??

What version of Windows are you running??

Spoiler: PCI-E Power Cable Extensions / Loose Cables Rant

If the stutters are *only* occuring when the GPU is used (even lightly for video encode/decode/transcode), I would remove the extensions (if you haven't done so already).
For time immemorable (literally, at least as long as PCIe 6-pin has been around) power cable extensions have been known to potentially cause these sorts of issues.

If you've already removed the PCIe power extensions from the circuit, I'd re-seat the cable at the PSU (assuming, modular PSU).
Speaking from experience, mis-seated PCIe 6/8-pins can cause stuttering.
(Worn-out cables inserted/removed far too many times, or cables internally frayed from being bent over too hard/too many times can cause the issue, too)

Edit: After watching the CS:GO footage and reading this

didnt do that yet i googled how those stutters look like, they come with audio stuttering i dont have that kind of stuttering but i can still give it a try

In my limited experience w/ AM4,
I get the stutters and audio glitches w/ an unstable SoC or too aggressive of Curve Optimizer.

HPET?

Its old school, but this used to be a problem for us back in the early to mid 2000's and this smells like an hpet issue. Epecially with more budget boards. like your B550.

 

[Dr. Dro]

@Montelo Did you check the fTPM setting as mentioned earlier by DR4G00N? I think that's worth following up on.

fTPM problem is supposed to have been fixed a few years ago, though. It was an AGESA bug, fTPM should not stutter on Zen 3 CPUs, as long as the BIOS is fully up to date. I wonder why did OP sidegrade from the 11400F to the 5600, but alas, it's not a pertinent question to the matter at hand. In any case, disabling fTPM is not recommended as it's an essential part of Windows security.

HPET would be my next look, if there were any changes done to this setting per the recommendation of "optimization guides". Windows has been very hostile to these changes as of late, in my experience. And of course, with a platform swap, a full reinstall of Windows is warranted.

 

[LabRat 891]

HPET?

Oh boy...
I was avoiding bringing that up, as it leads into a whole mess of back-forth on the merits/consequences (and complications).

https://www.reddit.com/r/QuakeChampions/comments/il4ha0/psa_how_i_fixed_my_stuttering_issues

This is a follow-up to this post:

https://www.reddit.com/r/QuakeChampions/comments/ikfeal/so_i_upgraded_my_pc_hoping_to_get_qc_running

First of all, thanks to everyone who convinced me to keep on trying: you guys were right! The problem was indeed not QC, but the symptoms were much more prominent than in any other app I tested. I've gone through the old thread and gave everyone who told me I was wrong their well-deserved upvotes.

So what was the issue? Simple answer: Windows10. Nothing wrong with my hardware or BIOS settings, and I probably could've fixed the stuttering without even upgrading my PC - too late to find out now, but maybe some of you can.

What finally pushed me into the right direction was this video:

Installing LatencyMon (free DL: https://www.resplendence.com/latencymon) unveiled huge latency spikes in my system for various reasons - most notable were probably weird behavior of my network drivers (Intel) and a lot of load coming from ntoskrnl.exe. These latency spikes can cause stuttering and audio-dropouts even without any load on the CPU.

I'm not 100% sure what steps in the vid fixed my issues, I first installed a firmware-update for my LAN and updated the drivers, which had a bit of a positive effect, too - stuttering remained though. I guess it was the bcdedit and fsutil commands (starting at about 7:00 in the video) that did the trick. I didn't apply any further steps beyond this, and after a reboot I immediately noticed that my system started a bit faster.

Running LatencyMon now shows that ntoskrnl.exe has almost 80% less latency for me and everything runs just the way I never thought it would. Feel kinda stupid, but also happy.. hope this helps anyone else!

This was on a fresh install of Windows10

The video is one of many guides on 'optimizing' HPET/systemtimers.
Do note: This is from reddit, and the video covers an ancient build of Win10. Take with a grain of salt.

'Last time I mucked with HPET/systimer things, was early Win10 era. IMO, one *shouldn't need to* mess with system timers to get consistent system performance.

My old Mainboard died and I couldnt find any new Mainboard for my i5 11400f and I didnt want to spend hundreds of € for something „better“ so I got the ryzen 5600 since it’s Not really that expensive and kinda on the Same Level as the i5.

I reinstalled Windows when I got my new Mainboard and CPU, then i reinstalled it 2 weeks ago because I thought it could maybe help but it didnt.

I didnt do anything with HPET Where is that and what should I do with it



EDIT: okay seems like i should Not Touch HPET

 

[Apocalypsee]

There is discussion on HPET on this forum you can read it here, be sure to jot down your current setting as it can cause issues if you did it wrong.

Thread 'revisiting hpet bcdedit tweaks: what are your timer bench results and settings?'

Sep 2, 2024

only for advanced users: be aware that once settings are defined by bcdedit these can cause irreversible changes and damage to your system such as low fps and stuttering until windows is reinstalled!

currently im in the process of revisiting some supposed tweaks for hpet and their implications.

the theory is that hpet can cause some issues like stuttering, high input latency or low fps performance.

some systems, games or apps may also run better with hpet enabled, some may run better with hpet disabled.

[LabRat 891]

I know; but people do some pretty dumb shit in the name of chasing fps.

Been there, done that; still do
Though, the case of/for timer tweaking is more "responsiveness" and less about raw FPS. The difference seems academic, but they're 2 entirely different 'interests' within the Enthusiast market/community. Stuttering and High Input latency are far bigger issues, for anyone that's not in it merely for the tweaking/benchmarking (or sensationalism).
