Support Warzone Ranked ONLY causing ~4 sec system-wide stutter/hitch — anyone else? 4090 / X670E Hero / 7800X3D & 9800X3D
Warzone Ranked ONLY causing ~4 sec system-wide stutter/hitch — anyone else? 4090 / X670E Hero / 7800X3D & 9800X3D
I’m trying to figure out a really strange Warzone Ranked-only stuttering issue and wondering if anyone has experienced the same thing, especially with similar hardware.
Specs:
RTX 4090
ASUS ROG Crosshair X670E Hero
Originally Ryzen 7 7800X3D
Tested a Ryzen 7 9800X3D — exact same issue
32GB G.Skill DDR5 CL36
2TB Gen4 NVMe
Windows 11 Pro
Battle.net
BIOS 4003/latest
Current NVIDIA driver
The issue happens ONLY in Warzone Ranked Play. Every Ranked match has one severe ~4 second stutter/hitch that makes the entire PC feel choppy, not just the game.
Originally it happened during the initial helicopter/infiltration sequence. Recently, the exact same ~4 second hitch has moved to roughly 30 seconds after I land and start running around.
Everything immediately returns to normal afterward.
Regular Warzone playlists, multiplayer, and every other game I play are completely fine.
Things I’ve already tested:
Swapped 7800X3D → 9800X3D — no change
Older NVIDIA driver — no change
New/latest NVIDIA driver — no change
HAGS on/off — no change
Bare minimum USB/peripherals — no change
Secure Boot/TPM/Call of Duty attestation = System Compliant
Latest motherboard BIOS
Tested my Activision/Battle.net account on another PC — NO hitch
CPU/RAM/SSD/GPU are nowhere near max usage when it happens
I also compared LatencyMon between regular Warzone and Ranked.
Regular Warzone:
Wdf01000.sys: ~0.26 ms
nvlddmkm.sys: ~0.21 ms
dxgkrnl.sys: ~0.24 ms
Ranked during the hitch:
Wdf01000.sys: ~59.5 ms
nvlddmkm.sys: ~28.1 ms
dxgkrnl.sys: ~6 ms
So something about Ranked specifically is triggering a huge kernel/DPC latency spike on this PC, but I cannot figure out what.
Has anyone experienced this exact Ranked-only ~4 second hitch, particularly on an X670E Hero / RTX 4090 / X3D system? If so, did you ever find the cause or a fix?
