How To Increase RSS Queues and tweak Receive & Transmit Buffers In Windows 10
You can't find this tweak anywhere else in the internet space. If You do it came from here.
Im going to start right away. RSS Queues tweak wont work unless your driver allows it. Rx & Tx increase works on every driver as far as I know. Like we know Intel NICs have only 2 Queues. For this to be working you need RRS to be enabled to activate the Queues.
This page is not updated. in fact IDK why keep it :D The main page is updated, better explained & has more info.
The registry path for this (Advanced tab Settings):
Is this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0001
and this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0001\Ndi\Params
You can find the correct path for your Network Adapter from Driver Key. Look the screenshot below. This should work on non-Intel network adapters as well.
You can change all network settings from here along with RSS Queues. The following steps should work on every Windows 10 version and Network Driver:
This is the default Intel settings.
We just need to add 2 more queues. Right click on empty background and choose String Value, name it "3" and on Value Data type "3 Queues". Repeat the process for the 4th queue but name it "4" and type "4 Queues". You can even add more if you have 6 or 8 core CPU. I encourage you to test it.I know up to 4 they are active. IDK for more.
Follow the screenshots bellow.
3 Queues
4 Queues
The server version of the driver supports more than 2 queues, you just need to "unlock" them. You have to enable Receive Side Scaling and Checksum Offload if you want to use the RSS queues. The number of RSS allocated Queues depends on the CPU core count. Keep that in mind. Increasing the queues improve the throughput for different kind of workload environments. Since v1803 Microsoft introduced RSSv2 which is faster & more responsive.
You have to know that it also has some minor delay but in many games it's better enabled, you just have to test it by yourself. If you use Matchmaking for testing you should leave someone else to do it for you because you obviously don't know what you are doing.
Now here's one more tweak relevant to Gaming/Performance and affecting Hit-Registration in games.
Tx & RX Buffers
You also can set the minimum and maximum values for Transmit & Receive Buffers (default values as well but you don't really need to change them, RSS Queues as well).
This is the registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0001\Ndi\Params\*TransmitBuffers
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0001\Ndi\Params\*ReceiveBuffers
TransmitBuffers
ReceiveBuffers
For good connections I recommend high values and for slower connections low values but you will
have to test which is the best value for you..
I found this tweak playing around in Registry Editor because it was bugging me, I had Realtek NIC & it have more queues & wider values range. It will be way easier if Microsoft release something like a Registry tweak guide or just describe the changes more in-dept than they do now and update it with the new Windows versions. The one they have now is very scares.
Please give this tutorial only to people who want to learn.

Additional Info:
If the path is changing the registry settings and the batch comands wont work. Thats why I made the tutorial. Never the less the batch commands looks like this:
