Hi
I recently upgraded my computer to eliminate microstutter in some games. Generally, games ran smoothly, but from time to time I experienced 1 second of stuttering in some titles. To illustrate the problem: a game without an fps lock ran at an average of 120 fps. I locked the fps to 80 and everything was fine, but every once in a while the fps dropped to 79 and I experienced a second of stutter. Locking it to 60 fps did not change anything. Then the fps dropped to 59 and I also experienced a second of stutter. I had a Ryzen 5600, 32gb ram 3600 cl 16 and a Gigabyte B450 Gaming X motherboard. To eliminate the problem, I bought a 7800x3d, 32gb ddr5 6000 cl 30 and a Gigabyte B650 Gaming X V2 motherboard but the problem unfortunately repeats itself.

After replacing the parts I tested The Last of Us Part II and I had an identical situation when I locked the fps to 80 sometimes I observed a drop in fps to 79 and a momentary stutter (I sensed that it was the fault of shaders loading during the game so I gave up on it). Now I launched Cyberpunk 2077 and it's exactly the same. High settings with dlss without RT. The game generates about 120 fps. I have a lock on e.g. 75fps, the graphics card works at 60%. When I run around the city it is smooth but when I come across some activity e.g. "robbery in progress" and I am displayed information about this activity fps per second drops by 1-2 and I feel stutter.

I tested with HWInfo monitoring enabled and it turned out that when I encounter a task in the game, the frametime increases, for example, from 13 ms to 15 ms, the fps drops by 1-2 and I experience stutter.Overall, 95% of the game is smooth, 1% low on 7800x3d is high but this momentary stutter... I tried changes in the bios: Expo on and off, Re bar on or off, PBO on or off, curve optimizer on or off. Completely factory bios settings did not improve the situation either. Tried settings v sync on or off, change display refresh 120,144,240hz

PC Specs
Mobo: Gigabyte B650 Gaming X V2 (latestBIOS)
CPU: Ryzen 7800X3D
GPU: Palit RTX 4070 Jetstream (driver 566.36)
RAM: 32GB Goodram 6000 cl 30
CPU Cooler: Fortis 5
PSU: SPC Supremo L2 550w (bought new about 3 years ago)
OS: Windows 10 home.
Monitor Acer 27" 1440p 240hz

Disks
System: Kioxia exceria 500 gb m2
Games: 1 tb ssd crucial
Media: 2 tb hdd seagate

All drivers (except GPU) are the latest.
All temperatures normal, during the game CPU about 70C and GPU 60C.
Total maximum power consumption of the computer is 350w.

I wonder if it's the hardware's fault or am I running into poorly optimized games?
What else can I do, I have the impression that this whole upgrade was a bad investment?

Almost every game stutters once in a while and some worse than others, even with the most beastly system so you may find yourself chasing your tail here for no reason.

That said, when having issues in specific title(s) I find it best to seek information either at its official forum, Steam page or even Reddit. It's quite unlikely that you have a hardware issue and more likely a game setting or Windows configuration issue (or no issue at all, some irregularities are accepted as normal). The people in those forums will be better equipped to answer those questions and you may discover a solution just by browsing the topic. I certainly have on multiple occasions.

The frame drops themselves are not a problem for me. As long as they do not cause noticeable stutter. And in my case, they do

Have you tried testing games that do not stutter often? Do you stutter more than normal. As others have said, stuttering in games to a certain extent is normal. If you stutter many times per minute, or the stutters are longer than 1/5th of a second or so, then you may have some sort of issue.

I don't experience stutter in every game. In those games where it occurs, it appears from time to time and lasts up to a second. It's not something that prevents the game from playing, but it is noticeable. On new hardware, I only tested TLoU 2 and Cyberpunk from newer games. From older games, I played Fifa 16 and RE 6 and there is no stutter in them. Cyberpunk has been on the market for a few years, it has received many patches, so I thought it was free from optimization flaws and ideal for testing new hardware.

Do you notice that perhaps the stutter happens when loading in game assets? This loading can pull CPU resources from the game to the storage device for the task briefly. Cyberpunk is a pretty CPU intensive game, and requires a lot of loading from storage devices. There are few loading screens as I am sure you have noticed.

Yes, fresh install. Newest bios , chipset and other drivers.Gpu driver roll back to 566.

In TLoU 2 maybe yes , stutters happend mostly when i go on new area. In Cyberpunk mostly when i found quest activity on the street and game display info about it on the screen but not always . I also discovered something interesting during testing. When I ran through the city for 2 minutes and reached an activity spot, e.g. "robbery in progress", then a momentary frametime jump and momentary stutter appeared. However, when I saved the game close to this spot and started the test, after reaching the same activity that nothing bad happened. Flat frametime, no stutter. Hmm, it may actually be related to some resource loading in certain areas...

NVMe storage is so fast now that when something major loads the CPU priorities change briefly. The assets have to load before the CPU can draw more frames, because they are based partially on those assets, for the GPU, thus a stutter occurs while loading them in. I have noticed anecdotally this usually only happens when CPU cores are already moderately taxed on something, like a game.

And what newer well-optimized game can you recommend for CPU testing? A game that should run super smoothly, without loading shaders, areas, etc. Not necessarily with great graphics, but using the CPU a lot? Maybe something like a classic RPG? Baldur's Gate 3?

i second that
cs2 is a great game for testing little stutterings (if there are any)

also this may sound crazy but i would not entirely ruled out
the possibility of the psu causing issues .
(even if not you should replace it anyway)

PSUs causing performance issues with other accompanying issues in tow is very rare, without causing any other accompanying issues is extremely improbable, but not impossible. I have seen over 10 faulty CPUs and not once seen a PSU cause such an issue, if that gives perspective with how rare such a PSU is. If I had to, I would bet the farm this is not a PSU issue.

As @dark_globe said, that PSU should not be used in your PC. Regardless of what is causing the stuttering, that PSU is a piece of junk that can destroy your whole computer. This is the cheapest PSU that comes from a reputable company right now that will last many years without issue if you are from the US.

SPC power supplies (now Endorfy) are not junk. In Europe and especially in Poland (SPC / Endorfy is a Polish company) they are popular and have good reviews. They are not high-end but they are solid power supplies for mid-range computers. The power of 550W may not be impressive but in the OCCT Power test the computer draws a maximum of 350W ( i have wattmeter connected )During gaming around 300W. So there is some reserve for my current components. I have never had problems with this power supply such as unexpected reset, computer hangs, damage to some component, etc., it also maintains decent voltages. People often have worse quality power supplies in their more powerful computers.

That particular PSU is in the E tier for AVOID.
  • SilentiumPC / Endorfy | Elementum E2 – Vero L2 / M2 – Supremo M1 Platinum / L2 / M2/ FM2

When deciding on this power supply I read reviews and user opinions. They were fine. I also did not find spc / endorfy on any "blacklist" of power supplies.
We've strayed a bit from the topic. Of course, I'm planning to replace the power supply in the next few months, but not because there's anything wrong with the current one, but as a final step in improving the current setup. The stutter I'm writing about doesn't look like a power supply problem to me. But maybe for peace of mind I'll be able to try replacing it with a better power supply and check.

The stutter is, as I said, extremely unlikely to be caused by the PSU. Nevertheless, I felt obligated to mention that the PSU is a liability, take my advice on it or not, that's up to you.

Stutter issues can be categorized as either a lack of resources during a particular task, or a software / driver conflict or optimization issue. I suspect that the issues you are having are in the latter category. Some stuttering from this category is rooted in the lack of resources, even if you have the fastest hardware, but in that case the problem shifts to optimization as the core issue. If the fastest hardware cannot effectively do a task then the blame is squarely shifted to optimization of the task.

I decided to do test with Spiderman Miles Morales with RT on ( all RT settings to max ) and RT off on High graphics preset + dlss quality and 80 fps lock with Riva Tuner. I use HWInfo monitoring and Generic Log Viewer .

RT OFF
RT ON max

The test is mainly swinging on a spider's web and running in crowded places on the street. No combat or cutscenes. Without RT I tested in mission 2 where we reach the park for Peter's outfit. The test with RT is the next task right after the cutscene in the park.
My gaming experience, apart from the graphs: in the RT test I once felt a slight stutter for a split second. In the non-RT test I didn't feel any stutters
But the situation is similar to Cyberpunk. Also a large FPS reserve (the card works at 60%) and a small increase in frame time causes a drop of 1-2 fps below the lock. In each of these games these stutters are not frequent and are not very noticeable, I can play calmly. I don't know what to think about it anymore
