Realtek Gaming 2.5gbe Family Controller Network Lag/Delay

[JimCarry]

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.

Hey! I bought the same ue300 usb ethernet dongle. What driver version you have? And what js the beast settings in device manager?

did you try it out yet? How does it feel?

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 ?

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.

Please tell me the name of the model?

Just wondering what was the consensus of this thread? I'm on windows 11. Is there any tweaks/drivers/settings with my onboard realtek 2.5gbe better or is buying the TP Link ue300 v5 better?

i am too lazy to do it,but i was in the same boat like you,try this use realtek oldest driver possible,and change receive buffers to 8 and transmit buffers to 4,i am using the driver from 2015 ,if you want i can show you how my reg looks like,if you can order the device try it ,if you dont works for you return it,but in my case i think it works,i can also show my complete build.

Great thread here regarding these Realtek "Gaming" Nics. I've had a few different computers with these and thought I was delusional the wifi was better, also a realtek product. I was having some serious latency/ hit reg issues. I've read multiple greivances thinking the NIC was at fault and people thought they were silly.

Turning off the RSS in the nic preferences seemed to help, I also adjusted buffers to 64/64 (Defaults was 1020 receive, 128 transmit (128 highest transmit) idk, weird. It doesn't seem like a placebo affect but I can still play on wifi if problems persist, Wifi 6 seems fine to game online with and I don't experience any of the classical latency or packet burst issues.

These NIC's seem really awful. But this is the 3rd one I had and it's a noticeable difference just playing on the wifi instead. But tell people that and they'll just think you're crazy.


Thx

Edit:
Seems stable and improved in the last few days. Changed buffers from 128 Transmit, 64 Recieve. Really low but the Transmit defaults to 128 and that's the highest it goes. Most instructions I seen said you want Transmit 2x Recieve, so 64 recieve. Perhaps the recieve buffer being defaulted to 1024 was causing some lag, idk.

Everything seems stable and my performance in Warzone is goated. That game has awful network issues but the difference is noticable in that people are no longer bullet sponges and I have a better hit reg. This was contrasted through different NIC's and wifi over the years, wifi now days is fine to game on with minimal latency usually.

I'm not trying to give criticism all to realtek but there may be some bad settings. Others have said in the last versions of windows the networking stack was conflicitng with NIC protocols or something as well. Wifi doesn't seem to be affected.

I'm not an expert but this had been going on off and on for years on different computers, I never knew exactly what was causing it.Turning off RSS really seemed to improve performance. But it may also be a conflict between the NIC and Windows Network protools, idk. lol

I've found with the Realtek onboard 2.5gbe its best to not use the latest drivers. I uninstalled the driver software deleted it and running the Microsoft driver from 31/03/2015 which I found was better than the latest one. Would be great if someone could test latency/jitter etc on all the realtek drivers and see which is the best and which NIC settings actually help.

Hi,

Idk. I'm just coming back after more experiments with the NIC settings. Basically you can turn RSS off but others said to lower the cue's to 2 instead of 4 and that seemed to fix it. It would take experimenting like RSS on, Offloads on/ off, RSS Cue's 2. Right now I'm back on RSS on, 2 Cue's, Checksums on/off, I can't tell a difference. I think the problem may have been 4 cue's being to high, idk. It seems to be functioning fine in 2 cue's, or all off in the preferences. Or just throw the pos in the trash and use the wifi or get a new one. I'm on a laptop so I can get a usb c ethernet adapter that may or may not be a pos.

It's fickle and hard for me to gauge whether the game is performing better, all I have installed is CoD which is p2p and warzone is hit or miss as well, so it varies game to game to person.

If it's that sensitive an issue for someone playing online something with dedicated servers would be ideal.

can you type command to see advanced options in powershell?

Yep which part are you after?
