I think I fixed it by going back to old Realtek windows driver from 2015. I've disabled Interrupt Modulation, Flow Control and Priority & VLAN which were on by default, and for a half an hour of playing DM i haven't noticed any spikes while discord was connected to the voice chat.. Could be worth a shot if you have REALTEK nic..

Where did you get the realtek driver from? I just had stock windows high definition audio driver because the realtek ones i download from realtek/my motherboard are bloated with realtek crap.

I just uninstalled the current driver I had, Windows installed the old one probably via windows update.. But that is not an audio driver, I've downgraded a ethernet driver.

Have you tried limiting discord upload speed using netlimiter ?

Yes, discord may be pretty heavy on system load. I usually close it for serious gaming sessions, and prefer to use Teamspeak which is very lightweight.

I recently have added a percentile view to show the V-Sync buffer in my new VRR low-latency frame pacing mode (dxvk), and Discord as well as Firefox are usually increasing the p95 and p99 percentiles quite significantly (like 100+ microseconds) which causes the mouse to feel a bit laggy.

Try debloating Discord with:

• https://github.com/rifteyy/discordoptimizer

• https://github.com/HerXayah/Discord-Fixer

Downside of discord-fixer is that keyboard shortcuts stop working.

Also, try putting discord.exe cpu affinity on last 2 cores (check only cpu 12,13,14,15) and cpu priority "below normal" in task manager. If it works, install process lasso to make it permanent, like Chief said few posts earlier.

Make sure the setting Enable Quality of Service High Packet priority is off. It under voice and video
