Fuser Overview
Learn what a Fuser is, how it works in a DMA setup, and how to identify its ports and controls before setting it up.
📺 What Is a Fuser?
The Fuser is a specialized hardware device used in DMA setups that combines the ESP overlay from your Radar PC with the live gameplay feed from your Game PC — displayed directly on a single monitor.
This eliminates the need to glance at a second screen or a laptop for visual information.
🎯 Purpose of a Fuser
The Fuser acts as a hardware overlay combiner, blending two video signals:
- Input 1 (Game PC): The unaltered game video output via HDMI or DisplayPort.
- Input 2 (Radar PC): The ESP overlay — boxes, outlines, and other visuals generated from DMA-read game memory.
By merging these signals, the Fuser displays cheat visuals directly on your monitor integrated with the game's native feed — without any software overlays like Moonlight, Discord, or OBS, which are more easily detected by anti-cheat systems.
