Introducing the NPU
Lag and Latency Reduction technology (LLR) uses a custom chipset called the Network Processing Unit (NPU) to allow parts of the game to run inside the Killer NIC. The NPU acts as a co-processor dedicated to running the networking portion of games and other applications.

A New Networking Model
LLR technology is completely Plug & Play, and works in all games. LLR literally bypasses the traditional Windows Networking Stack, enabling an entirely new game-optimized model of networking. The new networking model means there is a hardware interrupt for every gaming network packet, giving network traffic unprecedented speed and priority in your gaming PC.

Separating Networking and Graphics for Smoother Gameplay.
Games check the network for new data constantly – simple, but important checks ranging from “Is he shooting at me?” to “Is that door open or closed?” These checks are mixed with graphics and frames showing the result of the question (e.g. a closed or open door). LLR can answer these questions in just one CPU instruction. With LLR, your game has effectively separated graphics from networking. It can now dedicate more instructions to the other tasks – graphics and gameplay – that smooth your overall experience, especially during intense action.
