Hello everyone again. I have updates and comments. To start Faceit, I had to switch the BIOS to UEFI mode and set up Secure Boot. I think when I installed tp link ue 300 and installed a clean windows 11 image, I had CSM mode. After that, the feeling of a "heavy" mouse appeared again and registration deteriorated.

Then I decided to check the BIOS modes and found the following:

* when switching UEFI → CSM, the game became much more enjoyable again;
* at the same time, the BIOS automatically changed several parameters:
* Integrated Share Memory: 32 MB → 64 MB;
* Fast Boot: Enabled → Disabled;
* Above 4G Decoding / Crypto Currency Mining: Enabled → Disabled;
* UEFI → CSM.

After returning to UEFI, I manually set these settings the same way they were in CSM to see if it was the boot mode or one of the automatically changing settings that affected it. I'm continuing testing now.

At the moment, my subjective feelings are as follows:

* The mouse becomes more responsive;
* it is easier to make a micro duct;
* Easier to control shooting, especially with Deagle;
* Hit registration feels better;
* The game as a whole becomes more comfortable.

I am not claiming to have found the true cause, nor am I saying that CSM "reduces input lag". Perhaps the effect is related to one of the automatically changed BIOS settings, network adapter, drivers, or a combination of both.

If anyone has encountered a similar situation or can explain the technical reason for this behavior, I will be happy to discuss and compare the results.

Try to find the old driver like me and the author . Also reinstall windows , and immediately disable automatic driver updates in windows. By the way, I will remind you of the adapter version 5.0. Also try to roll back the driver in the device manager, if there is such an option . And read my last message , try to make the same settings in the bios . Just for the sake of testing , I am very interested .

As soon as I have some free time, I'll try to create a video to show you the difference. I would appreciate it if someone could tell me how to record and upload a video here, as I have no experience in this area.

I installed the driver you said but no luck so far. Can you share everysetting you changed on device manager?

Same thing here. Huge input lag while using it (default driver from 2015 iirc and disabled integrated LAN on bios). Couldn`t aim shit in CS2 with the input lag lol

Download the older version of the driver from the official website.
