Hi everyone, I am losing my mind over a consistent stutter (micro-freeze for ~0.5s) every 60 seconds when using Virtual Desktop with my Quest 3. This happens inside the VR, not on the pc monitor, as long as VD is connected to the headset.

The Symptoms:

• Occurs exactly every 60 seconds.
• VD Performance Overlay shows stable numbers (Game/Encode/Network/Decode) even during the stutter, except for the FPS that drops for the splisecond.
• Happens even when the PC is idle (desktop), ruling out game-specific issues.
• SteamVR is stutter-free, but looks so bad compared to Virtual Desktop.

Some of what I have already tried and hasn't affected it in the slightest (there has been much more but I forget):

• VR: Changing the bitrate, graphics quality, Codec, Video buffering (basically every single VD setting)
• Windows/OS: Disabled HAGS, disabled Game Mode, disabled background scanning, checked Task Scheduler for periodic triggers, Updated BIOS, Updated chipset, disabled C-States in BIOS, disabled USB Selective Suspend, disabled TPM, Windows performance recorder/analyzer, LatencyMon.
• Networking: Disabled WLAN AutoConfig, router is an AXE75, PC is wired via Ethernet, Quest 3 is the only device on the network.
• NVIDIA/Drivers: Clean DDU wipe and driver reinstall, set RTX 4080 to MSI (Message Signaled Interrupts) mode, forced GPU interrupts to specific cores using Interrupt Affinity Tool.
• Software/Services: Clean boot, removed monitoring software, disabled overlays, tested with/without process lasso cpu affinity.

I have maxed out my Gemini Pro tokens every day for the past 3 weeks exclusively for help troubleshooting but I have exhausted everything it could think of. If you have any other ideas/solutions or are experiencing the same, I'd love some help.

Cheers.
