Steam Controller interview full transcript — Valve programmer and engineer discuss design, latency, prototyping, and the joys of not having a kernel driver

Valve says the new Steam Controller is meant to feel familiar first, while still offering deep customization through Steam Input.

The design borrows ideas from Steam Deck input, but aims for a simpler setup flow and lower friction for PC players.

Valve revisited controllers now because it sees a better fit for a device that can handle both games and desktop use.

The company also emphasized latency awareness, prototyping, and compatibility across standard games and advanced control setups.
