I came across this topic by accident. I also have a built-in realtek 2.5, and I also see a delay in CS2. I bought a 1 GB realtek usb and it has the lowest input latency with Windows 11 drivers. I don't understand why this is so, the usb card lacks settings such as interrupt moderation and flow control, as well as receive and transmit buffers - 16 and 18. Can anyone explain why this is so? Why is the delay minimal on the usb network card? And it is on windows 11 stock drivers. If you install the latest realtek drivers, then flow control appears and the receive and transmit buffer is already getting 37, CS2 is starting to get worse. So the best option for me at the moment is a usb 1gb realtek on windows 11 stock drivers.
WOOOOWWWW!!! OH MY GOD! THANK YOU!!!
I bought a TP-Link UE300 USB ethernet dongle and it's really important to use the oldest drivers possible that get automatically detected at first (before any updates are applied and newer versions are added). I think I finally fixed my input lag after all of these years, I can finally hold angles on faceit. Thank you so much <3

I think it's better to leave the TCP/IP settings on default, for some reason it's worse for me when I disable all of the offloads.
Hi, i bought the same dongle, my driver name is realtek family driver.... i had the driver from 2015, then it updated automaticly after reboot to 2018. How can i go back to 2015 anf without auto update?

This is the one I had by default, then it updated to a 2024 driver- much worse, I tried another 2018 driver that I found online but the default 2016 driver was the best. It's strange that you have a driver from 2012 and not the same one as me because I got this same version on different windows builds
ok guys i just want to share my expierience i wrote it in another topic but i finaly find this one,so i buy the "TP-Link UE300, USB 3.0"
and first when i plug it as i will show the driver was 2015 with 8 or 10 options,and then i play premier and it was ok,but when i update to the latest driver for my device,version 5,the driver is from 2023,and it has more options,but its worse,i just want to show screens,and my msi utility how it looks,because its pluged to usb i cant change priority msi mode on or off ?
How can i get the 2015 again. It updated to 2018 and then i roll back the driver to 2015 and missclicked to uninstall. Now 2015 is gone and 2018 is there with more then 5 options. Fuuckk

No problem, go to Device Manager, find the Ethernet driver, then choose 'Update driver' and select 'Browse from a list'. A bunch of drivers will appear there for me, the last one, the 2015 version, actually works better.
