I can vouch for you on this LOL i just made my own post about it.
I’ve spent months fine-tuning my expensive Ethernet card like I’m defusing a bomb, registry edits, driver voodoo, praying to the latency gods — and still felt like I was aiming through syrup in slow motion. For the jokes, I plugged in a plastic WiFi stick that looks like it came from a cereal box… and suddenly my game feels like it’s being rendered by a sniper rifle powered by divine intervention. Everything’s locked in, pixel-perfect, headshots feel preordained. I’m out here getting clapped by a thumb-sized antenna with the soul of a microwave. Life is a simulation

so to be clear the fix is: you must use wifi and "plastic WiFi stick that looks like it came from a cereal box" ?

I really think its to do with how network processing works. with my usb dongle, message interupts went crazy since it was polling through my usb controller. higher cpu usage less performance in game but network packets were instant. the same behaviour can be seen in Linux, and with NetAdapterCx driver on windows, which uses polling also. check if your nic has a netadaptercx driver, its a windows 11 exclusive. it affects mouse feel tho beacuse of system choke from the polling. its like a massive vicious cycle. make 1 thing perfect the next goes shit, cant have evrything perfect. we need a seperate dedicated cpu for processing dpc/polling/interupts imo

thanks for sharing / explain.i am on win 10 but what do you mean by "message interupts went crazy" ,also i wanto to ask can you give me link for the one you buy,and do you touch any settings on it,also cmd default ?

thanks,but i still dont get it,you mean that when for example,when you go in msi util,msg limit when up or ?also when you plug the "realtek 8812bu" in the usb do you change any advanced settings on it or? and what is you cmd?

I guess you havent much experience with inteupts affinity/policies yet so id research it a bit before you change anything as you can easily make performance worse. it depends a lot on your hardware and how its configured.

Go in advanced network adapter properties and for rss queues, change msi limit for the same amount of queues you have. that make it a bit more stable for me.

however i do notice youre using the same ethernet controller as my motherboard has. You can try the netadaptercx driver. you can download it here https://www.realtek.com/Download/ToDown ... oadid=4342

i have i use i did put my nic on my last core.

i dont use rss.if you increase msg limit for some driver and if the irqs dont go up as well it means it does not work.

i use the latest one 2025 the one that you are linking i think is the same but with power savings enable or i am in mistake ?

try the one with netadaptercx, not the ndis one, i like netadaptercx one

ok whats the diff ? this is win 11 i am win 10?

I've been experimenting with some settings that needed to be disabled in gpedit and now I have massively reduced desync. The last two that disable cmd and regedit should be set before playing games and reenabled when needed. There is a potential for placebo as always but the reason I'm sharing these is because I notice a huge change in online games which have been nearly unplayable until now.

That should run without an issue.

Has anyone tried any after market Intel pcie to Ethernet adapter, seems like the issue is with Realtek Gbe family controllers
