I got the AI to summarize it because I was talking to it about it.
Symptoms
While playing
Ace Combat 7, after playing for a while you started getting noticeable stuttering. At the same time, the music you were streaming through
Radio Garden in Firefox also stuttered. Your audio was being played over
Bluetooth.
The fact that both the game's performance and unrelated audio were affected suggested something broader than AC7 simply losing FPS.
What we've checked
Your hardware monitoring looked generally healthy:
- Ryzen 7 5700X3D: peaked around 57°C — excellent.
- RTX 3070: peaked around 72°C, with normal-looking clocks, utilization and power.
- VRAM: only reached about 3.4 GB / 8 GB, so VRAM exhaustion wasn't an issue.
- You recently had an unexpected Windows automatic disk repair, which initially made the SSD suspicious.
- You installed Samsung Magician and its initial short diagnostic reported that your Samsung 870 EVO appeared healthy.
So far, we haven't seen evidence that the CPU/GPU is overheating or that the SSD is obviously failing.
The important discovery
We ran
LatencyMon while you played. The stuttering happened during the test, although
less frequently than it had previously.
LatencyMon recorded a huge latency event:
Wdf01000.sys — ~438 ms maximum DPC execution time
It also measured an interrupt-to-process latency of approximately
1.07 seconds.
That's large enough to plausibly cause the kind of
system-wide hitching/audio interruption you experienced.
Wdf01000.sys is Microsoft's
Kernel-Mode Driver Framework, though, so we haven't identified the actual offending device/driver yet. We should
not try to delete or replace that Windows file.
Where we're going next
Bluetooth became particularly interesting after you told me that's how you were listening to Radio Garden. Your LatencyMon capture also showed Windows' Bluetooth driver (BTHport.sys) active, although that
doesn't establish that Bluetooth caused the problem.
Our next troubleshooting step was deliberately simple: reproduce the problem while changing
one variable at a time—for example, play AC7 without Firefox/Radio Garden, then potentially test without Bluetooth audio.
So our current working hypothesis is
a driver/device-related DPC latency problem, with Bluetooth/audio/USB-related components worth investigating. We haven't found evidence yet that your recently repaired computer has suffered another major hardware failure.
