01.How does Windows 11 handling your Network Card?
Windows 11 is optimized for the average user who does large downloads. To save traffic, the system uses the **Nagle Algorithm**, which waits to 'fill' a data packet before sending it.
In games like Valorant or CS2, this small wait is what generates the Lag Spike. We need to force Windows to send every small packet of information (click, movement, shot) instantly, without waiting for anything.
Critical Setting: Interrupt Moderation
In Device Manager, network cards have an Interrupt Moderation Rate setting. We recommend disabling this in competitive scenarios, allowing the system to process each packet in the millisecond it arrives.
Don't do it Manually.

02.Key Registry: TCP Ack Frequency
By setting TcpAckFrequency to 1, Windows sends an immediate confirmation packet for each packet received, rather than waiting and grouping multiple packets.
Registry Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces.
This drastically reduces RTT (Round Trip Time) and stabilizes the competitive experience.
03.The Voltris Network Optimization Advantage
**Voltris Optimizer** automates all the technical "alphabet soup" of network cards, configuring not only the Registry but the internal properties of the driver.
- **Packet Optimization:** Prioritizes game packets over background traffic (background downloads).
- **Net Tweak:** Disables the bandwidth limit that Windows imposes for updates while you play.
- **Gamer DNS:** Offers DNS servers with the shortest physical route to central FPS servers.
