Turn off Nagle's algorithm (TCP)

OptionalNeeds administrator rightsReboot needed

Windows does not bundle small TCP packets and acknowledges received ones at once (TCPNoDelay and TcpAckFrequency for each connected network adapter).

Expected effect

Helps only games that use TCP: some MMOs and MOBAs, older online games. CS2, Valorant, Fortnite, Apex and most shooters use UDP — the tweak does not affect them.

Possible side effects

A few more small packets on the network. On a slow or busy connection large downloads may be slightly slower.

What exactly changes

Registry key	Value	Type	New value
`HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{d2a74f80-ef31-4586-b07f-ed7c4240016e}`	`TcpAckFrequency`	DWord	`1`
`HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{d2a74f80-ef31-4586-b07f-ed7c4240016e}`	`TCPNoDelay`	DWord	`1`

How to undo it

Before a change NyxBoost saves the previous values; "Revert" brings them back and removes those that did not exist before.

In NyxBoost: Recovery → “Revert” next to this setting's entry.
Without the program: open the Registry Editor (regedit), go to the key from the table and put back the previous value — NyxBoost records it in its change history.

How NyxBoost checks the result

After applying, NyxBoost reads the values again and compares them with the expected ones. To see the real effect on your PC, use FPS Lab: it measures the same game before and after.
