Open | Hardware Help me fix my microstutters(100-130ms)
I have persistent 100–130 ms frametime spikes across many games despite replacing nearly every major PC component. Looking for ideas beyond the usual troubleshooting.
\\# Current PC Specs
\\\* Ryzen 7 5700X3D
\\\* RTX 4060
\\\* ASUS PRIME B550M-K
\\\* 16 GB DDR4
\\\* Samsung PM9A1 NVMe SSD
\\\* 650 W PSU
\\# Previous Hardware
The issue has persisted despite replacing nearly every major component over time:
\\\* Previous GPU: RX 6500 XT
\\\* Previous motherboard: Gigabyte B450M DS3H V2
\\\* Different CPU
\\\* Different RAM
\\\* Different SSD
\\\* Different PSU
At this point, almost the entire PC has been replaced.
\\# The Problem
Many games suffer from severe frametime spikes (typically around \\\*\\\*100–130 ms\\\*\\\*) despite otherwise normal performance. Average FPS is often fine, but the game visibly hitches.
Examples of affected games include:
\\\* Deadlock
\\\* Talos Principle 2
\\\* Rogue Trader
\\\* Phoenix Point
\\\* Chaos Gate
\\\* Zero Parades
\\\* Expedition 33
\\\* Xenonauts 2
\\\* Expeditions: Rome
\\\* BIOMORPH
\\\* GRIME II
\\\* Pyre
\\\* Wildermyth
\\\* Mewgenics
\\\* Esoteric Ebb
Games that are smooth include:
\\\* Portal 2
\\\* Hades II
\\\* Mina the Hollower
\\# One Interesting Pattern
One thing we've consistently observed is that \\\*\\\*standing still and simply rotating the camera usually does not cause stutters.\\\*\\\*
Instead, the stutters mostly occur \\\*\\\*while moving through the game world\\\*\\\*.
Because of that, it seems like the issue may be related to some aspect of world traversal or world updates rather than camera movement or raw GPU rendering.
We're \\\*\\\*not claiming that's the root cause\\\*\\\*, only that it's the strongest pattern we've found so far.
\\# Diagnostics Performed
We've spent a lot of time collecting data rather than guessing.
\\# CapFrameX
\\\* Frametime spikes consistently reach around \\\*\\\*100–130 ms\\\*\\\*
\\\* Average FPS is otherwise normal
\\# System Monitoring
During the spikes:
\\\* CPU usage stays normal
\\\* GPU usage stays normal
\\\* CPU clocks remain stable
\\\* GPU clocks remain stable
\\\* Temperatures remain normal
\\# LatencyMon
No significant DPC latency issues were detected.
\\# GPU-Z
PCIe Render Test reports the GPU operating correctly at:
\\\* PCIe 4.0 x8 @ PCIe 4.0 x8
Resizable BAR is enabled.
\\# Troubleshooting Already Done
We've already tried or ruled out:
\\\* Replacing the CPU
\\\* Replacing the GPU (AMD and NVIDIA)
\\\* Replacing the motherboard
\\\* Replacing the RAM
\\\* Replacing the SSD
\\\* Replacing the PSU
\\\* Fresh Windows installation
\\\* Testing under Linux
\\\* Updating the BIOS
\\\* Loading BIOS default settings
\\\* Different monitor
\\\* Different DisplayPort/HDMI cables
\\\* Different electrical outlets/buildings
\\\* Temperatures and thermal throttling
\\\* PCIe link issues
\\\* Basic resource bottlenecks
\\# Why We're Posting
At this point, we're no longer looking for the standard suggestions like:
\\\* Reinstall Windows
\\\* Update drivers
\\\* Enable XMP/DOCP
\\\* Check temperatures
\\\* Replace the SSD
Those have already been covered.
We're hoping someone recognizes this pattern or has experience with similar cases.
The current evidence seems to suggest that \\\*\\\*something about certain games' world traversal, asset loading, scripting, or world simulation workloads causes intermittent stalls\\\*\\\*, while games with more self-contained levels (Portal 2, Hades II, Mina the Hollower) run smoothly.
Again, we're \\\*\\\*not saying that's definitely the cause.\\\*\\\* It's simply the strongest correlation we've found after months of troubleshooting.
Has anyone encountered anything similar or have ideas for what could cause this kind of selective frametime behavior?
