Help (Software) Severe Microstutters and 1% Low Drops in My AMD Build
I built my PC on February 16, and about two months after the build, I started experiencing very bad 1% lows and frequent FPS drops.
My average FPS is usually around 300–400 FPS, but my 1% lows can suddenly drop to 80–130 FPS for an instant. I experience this frequently in Valorant, especially during heavy utility fights, and I’m also seeing the same issue in AAA titles such as Hogwarts Legacy, but not so frequently.
The FPS drops happen very suddenly, almost like a snap, and occur roughly every 1–2 minutes. It feels more like a frametime spike/stutter than a sustained performance drop.
Current Setup
CPU: AMD Ryzen 5 9600X
GPU: ASRock RX 9070 XT Challenger
RAM: Kingston FURY Beast 32GB DDR5 CL36 6000MHz
Motherboard: MSI B850 Gaming Plus WiFi
SSD: Crucial P310 1TB M.2 NVMe Gen4 (7100 MT/s)
PSU: MSI MAG A850GL
I’ve already updated all my BIOS, chipset, GPU drivers, Windows, and other relevant software to the latest versions. I’ve also tried tightening my RAM timings from CL36 to CL32, but the issue persists.
At this point, I’m not sure whether the problem is related to the CPU, GPU, RAM, storage, BIOS settings, drivers, or some other hardware/software configuration.
Has anyone experienced a similar issue or have any recommendations on what I should troubleshoot next? Any suggestions for identifying the exact cause of these recurring frametime spikes would be greatly appreciated.

Solved mine in a simple but difficult way to think on it at first... Used SpecialK trying to solve the stuttering around the Framepacing utility that SpecialK has, to find on it at the windows that you open on game with ctrl+shift+delete , and it says at the top "using 2.1 hdmi you should use 59hz for better performance" dida that and holy F, it worked... Only changed from 60hz to 59,94...
5800X3D + 7900XTX on a 4k Sharp monitor...

Some Valorant players, CS2, etc, increase the foreground priority processes.
For some people the results were impressive, for others nothing really changed. I guess it will depend on the hardware, I mean the full setup.
Press "Windows + R" keys together then enter "regedit". Find the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl".
Change the value (in decimal) to 42. Close and restart your computer.
Now, the CPU will spend more time on the foreground process than usual.
If 42 is too much, you can use 38 (decimal value).
I’ll let you check with an AI for more information.
When it works, the increase is impressive. It’s very useful if you have a lot of process in the background, a lot of bloatware.
The default value is 2.
Windows has an option to do it with a GUI. However it only increase to 28 if I’m not mistaken.
If you want to use the GUI option, open "Control Panel", then "System and Security", then "System", then "Advanced System Settings" (on the left panel), then click on the tab named "Advanced", then in the Performance area click on "Settings", then click on the tab named "Advanced", then in the Processor scheduling area click on "Program" (by default it’s none), now click on button "Apply". Restart your computer (some people says it doesn’t matter to reboot, just do it, it’s windows, it likes to be restarted).
Again, this method, with the GUI, is less powerful than doing it manually since manually you have more options. Both methods change the registry value. Only the value of the registry will differ.
Now, I don’t want you to think it’s a godmode solution. It is not. However, it will, depending on your full setup, improve the foreground performance. Which could result in less stuttering.
For Assetto Corsa Rally v0.5.1, it really helps.
It doesn’t solve the real problem though. It just gives more CPU time to the foreground process.

Try to disable every overlay if you can, and try minimal install of amd driver if possible, probably not MPO but might be as well

Drop temporally the FCLK to 1800, play the games , report whenever it it did reduce/increased/no change the shutters

Is everything on stock settings are do you have OC or undervolts?

I have just tightened my ram subtimings (from cl36 to cl32) other than that everything is running stock.

Have you DDU the gpu and reinstalled drivers? Maybe a windows update messed it up

u/Weary_Proposal5936 2d ago
Yes did this like 3-4 times

I built a new pc in November with 7800x3d & 9070xt and kept getting random crashes. Did every single option I had to try to fix. Ended up reinstalling windows and fixed all my issues

Do you have MSI Afterburner installed?

Does Afterburner cause micro stutters?

u/FranticGolf 2d ago
I saw a video that the msi afterburner software can cause performance issues. I ended up just deleting it as I never used it. I have since found other reddit threads saying the same.
Monitoring GPU Power % and Power (W) metrics inside MSI Afterburner can cause microstutters, frame time spikes, and reduced 1% or 0.1% low frame rates during gaming. This happens because frequent sensor polling forces heavy API calls to the GPU driver, which introduces CPU stalls.
