What is SteelSeriesEngine3.exe?

SteelSeries Engine 3 is the companion software that centralizes customization for SteelSeries peripherals such as mice, keyboards, headsets, and other devices. It runs in the background to apply lighting effects, configure macros, manage profiles, and update firmware across connected devices.

SteelSeries Engine 3 runs as a background service and user interface that communicates with supported hardware via USB/Bluetooth, loads profiles, applies lighting effects, and handles firmware checks through a local API and event-driven messages.
