Realtek Ethernet Controller - Input Lag Issue

[crack]

I actually found an issue now. Everything started about 2 months ago when I bought a Logitech Superlight 2 mouse. After that, my internet began dropping from time to time. I also started getting packet loss here and there, and I thought it was related to the NDIS driver/ISP.

When I was re-plugging my devices, I accidentally changed the port to another and thought that Realtek Driver fixed an issue. However, now, after doing some research, I'm sure that it’s caused by EMI since I’m playing on 4k polling rate (I used to play on 1k). When I plug my mouse next to the ethernet adapter, the mouse is pretty smooth, however, I get packet loss and ethernet adapter disconnects. And when I switch the USB port, the internet works perfectly with no packet loss, but the mouse feels off.

As soon as I plugged my 4k polling rate mouse into the USB port next to the ethernet adapter, my internet speed dropped from 1000mbit/s to 100mbit/s as Speed & Duplex is set to Auto Negotiation. That's crazy.

The more I am browsing this forum for solutions for input lag the more I keep going towards insanity.

I probably found a fix for that, however, I'm still testing. Gonna reply tomorrow with the conclusion. By the way, I think that buying external ethernet adapter would be 10/10 solution for me, but I try to fix my issue without purchasing it.

I 100% got rid of my mouse input lag by uninstalling the extra Microsoft visual c++ in control panel. I only have the 1 there now and months later the desktop etc feels smooth as still.

but you need them for games to even launch, no? they get installed automatically when launching new games?

Some games, not all of them. I only play a handful now

Here i'll explain my issue even better. The only USB 2.0 port on my MOBO is next to the Ethernet Adapter. The mouse on USB 2.0 is very responsive and smooth, however, when I use it (even with dongle), I get packet loss and internet speed drops from 1000mbit/s to 100mbit/s, so I have to restart my PC to get the speed back, however, it will drop to 100mbit/s later again. If I use USB 3.0 mouse becomes slow and unpredictable. Any ideas how to make USB 2.0 usable without buying External Ethernet PCIe card?

what mouse? hz? cpu? fps drop when mouse moving?
also, try to play with cores.
https://github.com/spddl/GoInterruptPolicy
that is good soft.
move nic controller on diff cores.
also, it moves only isr.
for move dpc you need play with rss.

Logitech Superlight 2 (using 4000 Hz), 14600KF.
Actually, you’re onto something about RSS. For some reason, as soon as I disable it, things get worse, while with it enabled the mouse feels better. What’s more, in MSI Mode Utility 3 I changed the Realtek Controller interrupt priority from High (default after reinstalling the driver) to Undefined. This option moved the NIC to the E-Cores, and this tweak also improved mouse snappiness.

I also applied another tweak I found on a forum, after which both the internet and the mouse feel more responsive. The mouse is snappy, I don’t get packet loss or internet disconnects, and now USB 3.0 works fine, better than before.

Here’s what I did:
1. Uninstalled Intel USB 3.20 eXtensible Host Controller – 1.20 (Microsoft).
2. Turned OFF my PC with Power Button. Unplugged the Ethernet adapter and all USB devices. After that, I turned OFF the PSU and held the Power button for a minute to completely discharge any remaining electricity.
3. Turned ON the PSU, then the PC. Plugged in all devices (into the ports listed in the motherboard documentation for peripheral connections) and plugged in the Ethernet adapter last.
After that the game and the mouse feels really smooth.

Note: I had tried this same process earlier, but without unplugging the Ethernet adapter. As soon as I reconnected all the devices, my internet started disconnecting every few seconds. So I repeated the process, but this time unplugged the Ethernet adapter and connected it at the very end. After that the game and the mouse became really smooth. I have a feeling the issue might come back after some time, but at the moment everything is working fine.

I’m ready to help anyone because I know the hell I went through with these problems and everything I tried in order to solve them.
I'm not very active here, you can add me on steam : https://steamcommunity.com/id/destroyerpalanka/ so we can try to fix this things together.

I tried getting the netadaptercx twice, let the installer run, reboot and realtek adapter disappears from device manager after reboot. First time I brought it back after uninstalling it and reinstalling the ndis driver, then disable & enable the onboard LAN from bios but on the second time it didn't work so I had to CMOS reset to bring it back.
