I have a 2.5Gbe adapter:

Manufacturer: Intel

Description: Intel(R) Ethernet Controller (3) I225-V

Driver version: 2.1.3.15

Physical address (MAC): C8-7F-54-0B-C5-FF

But I don't use it in 2.5Gb mode.

Occasionally I get disconnected thanks to joining Discord VCs while in VRChat, but I cannot say the two are related.

I've heard that in 2.5Gb mode, on my motherboard, some people have had their network chip overheat and die.

I'm using an ASUS ProArt X670E-Creator Wifi, nice IO options on this board. Lots of USB.

But again, on its own, no issues, my disconnects are only related to Discord VCs

Very frequently (sometimes after only a few seconds, sometimes a couple minutes) I've been getting "Your connection to VRChat was interrupted. Verify connection and try again."

This didn't use to happen on this hardware setup, so presumably a software change triggered it. I recalled that I'd upgraded my NIC drivers around the time I started seeing this problem, and after rolling them back the problem appears to have gone away but I've done very bad science here and changed a bunch of other variables between tests.

Motherboard: ASRock X670E PG Lightning

NIC: Realtek RTL8125BG 2.5 Gigabit LAN

Problem(?) Driver: 10.69.1121.2023

Working Driver: 10.53.1001.2021

No idea if this is the same issue described in this thread or if the driver upgrade was actually the cause, but maybe other affected users here would be interested in testing an older driver version?

Still having this problem on August 2024 with an Asrock B650 livemixer, 4080 , 64gb 6000MT/s CL30.

I have a Gigabyte Z790 Aorus Elite AX and this sounds exactly like the problem I've experienced since upgrading to this rig.

Can anyone confirm that using WiFi on the same setup prevents this?

I have this too on a Gigabyte AB350M-Gaming3 motherboard.

For me the time until it starts happening is around 1h - 2.5h. This timing is usually somewhat consistent on nearby days but changes constantly over the months hence the large range here.

Someone mentioned that it might have something to do with highly populated instances, but it happens to me in literally all instances. Doesn't matter if its player cap or just 3 other people besides me.

One thing I have seen no one mention is that the IK jitter starts happening at very slightly different times for each person observing me. So there is usually a small time window of 5-10 minutes where half the instance sees my IK jitter and the other half still sees me smooth.

It seems I have successfully fixed the issue,my friend said that the jitter was no more after I woke up from sleep.Here's what I did :

I updated my Realtek Gaming 2.5Gbe Family Controller Driver to this version which is the latest:(attached document)

I also noticed after updating it reset some manual changes I made to the adapter settings ,so I will just post them here.Most of it is power saving features,which were re-enabled :

Advanced EEE : Disabled

ARP Offload : Disabled

EEE-Max Support Speed : 2.5 Gbps Full Duplex

Energy-Efficient Ethernet : Disabled

Flow Control : Disabled

Gigabit Lite : Enabled

Green Ethernet : Enabled

Interrupt Moderation : Disabled

IPv4 Checksum Offload : Disabled

Jumbo Frame : Disabled

Large Send Offload v2(IPv4):Disabled

Large Send Offload v2(IPv6):Disabled

Network Address : Not Present

NS Offload : Disabled

Power Saving Mode : Enabled

Priority & VLAN : Priority & VLAN Disabled

Receive Buffers : 512

Shutdown Wake-On-Lan: Enabled

Speed & Duplex : 2.5 Gbps Full Duplex

TCP Checksum Offload(IPv4) : Disabled

TCP Checksum Offload(IPv6) : Disabled

Transmit Buffers : 512

UDP Checksum Offload(IPv4): Disabled

UDP Checksum Offload(IPv6): Disabled

VLAN ID : 0

Wake on Magic Packet : Enabled

Wake on pattern match : Enabled

WOL & Shutdown Link Speed : 10 Mbps First

In addition to this,the options in the Power Management are all checked(attached document)

Not sure how this plays out for other network cards ,but hope it helps

perhaps disabling msi mode works, does a fixed value for interrupt requests? The requests are in range to prioritize certain traffic which is causing this?

Has anyone tried running their 2.5 Gbe lan at 1 Gbe or 100Mbps,and check if the issue persists?Also this seemingly does not happen in other games because they don't have to load random avatars and everything is pre loaded,can someone try to reproduce this issue in something similar to vrchat,like neosvr?It seems the more other users change the avatar,the worse it gets,I suspect it has something to do with some sort of network cache

would simply buying a pcie network card be a temporary fix for this?

I too experiance this issue im rocking the x670e PG Lightning im unsure how to fix it or if its even possible to find a temp fix
