Question Windows constant micro-stutters

[Ronin625]

It started when I did a fresh install of Windows 11, thinking it was Windows 11 that was the culprit I fresh installed Windows 10 again but the problem persists and I feel like I've tried everything at this point

It's not only in games, I see it when minimizing and maximizing application tabs.

I installed RivaTuner to check the FPS stats and the games seem to half in frames when they stutter, when playing RDR2 I go from 130 to 60 and it's constant. The graph shows clear constant dips I can provide screenshots for.

These are the things I tried, honestly out of ideas of what it could be

• Rolling back to Windows 10
• Reinstalling drivers/installing all updates
• Disabling ‘Erase fTPM to keep record and continue to boot” in BIOS
• Resetting BIOS to default values including CPU and memory OC values
• Using DDU, installing the newest GPU drivers and old ones
• Reinstalling all chipset drivers/including installing older versions
• Disabling Dynamic Tick and Diagnostic Policy Service
• Checking for errors using ‘dxdiag’
• Disabling all anti-virus components
• Disabling G-Sync
• Force enabling V-Sync
• Running Prime95 for CPU errors (nope)
• Running MemTest64 for memory errors (nope)
• Running SFC and DISM
• Using CrystalDiskInfo for SSD errors (nope)
• Turning off all unnecessary tasks in Task Manager
• Using a different monitor with a different cable
• Disabling Game Mode
• Setting Power mode to Ryzen Plan High Performance
• Running LatencyMon for DPC issues (the highest reported driver was ‘nvlddmkm.sys’ at ~1300)

Thanks for any help

So, what I've noticed is that you have BIOS version 5302 from 11/10/2023 which it says on the official site & there has been a BIOS update for 5502 since 9/20/2024 not saying you didn't try it. This happened to me before; I had a really great setup and it started micro-stuttering; frame-tearing, all that stuff and couldn't figure out the problem either til I saw a BIOS update that was almost 3 years older from my current version. So I updated, reconfigured my settings and BOOOM . . . . . I thought my PC was like new.................................................food for thought

Ah yes, that was in my to do list, I’ll try it and see if it works

Unfortunately, it's still there...

I tried a few more things like disabling HPET, and fTPM completely.

I actually did a fresh re-install of Win10 a bit more than a year ago and everything was fine. I'm starting to think when I upgraded to Windows 11 now, it changed something and that's what's causing it, but it doesn't make sense why it still happens on a fresh install of Win10.

Alright, I gave up to re-installing Windows for the 3rd time, this time without installing any 3rd party drivers. Just basic Windows updates and a Nvidia Game Ready driver, the stutter seems to be gone
