InputLag SOLVED Realtek USB / TP-LINK UE300 USB 3.0 Adapter

[wasted42]

Hey everyone, I'm one of you who's been dealing with this same issue for years. I'll try to keep it as short as possible and just share what I've noticed in the last 10 days and no, this is not placebo.

For the past ~5 years I've had an input lag problem.
To put it simply: 600–700 FPS @ 400Hz BenQ monitor still feels like I'm playing on 60Hz with 100 FPS. Mouse sensitivity constantly feels like it's changing even though it's always the same (2SENS@400 DPI@1000Hz). The screen feels shaky, no real mouse control, and I can't move properly in-game. I only play CS.

PC specs:
Ryzen 9800X3D, RTX 5070 Ti, 6000MHz CL30 EXPO RAM

I've tried literally everything. I moved houses (apartments) multiple times, bought UPS, tried 3 different monitors (240Hz, 360Hz, 400Hz), replaced every single PC component 3–5 times, mouses, keyboards.. Nothing helped.

Then I read here on the forum about trying a TP-Link UE300 USB 3.0 Gigabit Ethernet adapter.

I bought it and started testing, BUT AT FIRST I MADE A MISTAKE I updated it to the latest driver, so I didn’t really feel any improvement.

Later I did a completely fresh Windows 11 install. I blocked automatic driver updates and installed drivers manually, except for the USB Ethernet adapter.
So:
Driver date: 26/09/2015
Version: 11.4.211.2022
When I open Advanced Settings for the Realtek USB GbE Family Controller, I don’t even have all the usual options like transmit/receive buffers, etc. I only see a few basic ones:
https://prnt.sc/5pKrulGmkCFJ

And now the important part:

Since I left it on that default/old driver - the difference is HUGE. The image is no longer shaky, everything feels smooth, I finally have proper mouse control. I’m not exaggerating , this is not placebo. I literally realized I wasn’t crazy.

The only downside is that sometimes bullets feel a bit “weird” in-game when shooting, but honestly I’d rather play like this than go back to how it was before. (repeat sometimes feel not non stop)
My image is smooth all the time, I feel it in the mouse. Only sometimes the recoil is a bit strange, but I think that can be fixed with a better USB adapter or the right settings. So I'm asking someone to share their opinion.

That’s why I’m posting this:

Maybe someone can try this since the adapter is cheap or they already have it / test it with older drivers
If anyone has a recommendation for a better or higher-end USB Ethernet adapter, PLEASE SHARE
If anyone knows how to properly tune the Realtek USB GbE Family Controller or unlock full advanced settings, I'd appreciate advice

If anyone else had similar experience or knows more about this adapter, please share. I really want to understand this better and test more things.

At this point I'm convinced my issue was actually internet/adapter related, not electricity or anything else.

Thanks!

What version of the TP-Link UE300 USB do you have? 4.0, 5.0, 5.2? What chipset does the adapter properties show: ASIX or Realtek? Can you take a screenshot? Have you disabled the integrated Realtek module in the BIOS?

[Sygey3]

Can you take a screenshot of the box, they just come in different boxes.

i've heard only great things about the Tp-Link UE300. but people say "Don't buy the 5.2 version because it's using ASIX chipset not realtek" which version do you have exactly? Ty for your Post!

I have it in my shelf and never used after a couple of days of good gameplay. What people don't understand, before buying anything check all previous posts about this issue, it will take you couple of days, but you will save huge amount of money. Any pci-e ,usb and other adapters, dang it even wifi adapter will give you good gameplay for a couple of games/rounds/days and then go back to shit. Please stop with these type of posts.

https://prnt.sc/bulrTFjMrk_y < same driver version as yours
https://prnt.sc/ZL7NbYnmYFln < more adapter settings.

So with ethernet disabled in bios you did not had any problems ?

yes man, https://prnt.sc/EmZBVo_huaNK (Tp-link UE300 USB 3.0 to Gigabit Ethernet Network Adapter)

Still nobody knows anything more about this?

which usb model is considered the best for gaming/cs, and should the drivers be updated?
if so whats the proper way to set everything up?

Could you please share the Version of your TP-Link UE300 USB 3.0 ? It should be somewhere on the box next to the barcode.

Is it 5.0, 5.1, 5.2 or other?

And yes this is a known issue. Some motherboard topology are not as good as others. Sometimes some components can shares PCIE lanes / interrupts with each other, or it can simply be a poor Ethernet implementation. This is not linked to a motherboard brand or anything, as each model from each brand will perform differently depending on how the motherboard topology has been engineered.

It has been discussed in great lengths in the past on this forum check here { viewtopic.php?t=10624 }

Can you also share what is your current motherboard?

Bought it for myself today. It's way worse than a good mobos realtek nic with netadaptercx drivers. Pls dont waste your money and time on this. Regardless ty for the post

Did you not try turning off ethernet settings and playing on wifi? Was there difference?
