I don't think I've encountered anyone, in the wild, who actually uses Steam's Remote Play game streaming feature since the days of the hardware Steam Link (and what tremendous days they were). In 2026, I think most people making use of in-home streaming tend to default to programs like Apollo and Moonlight.
But Valve keeps working on it, perhaps with renewed vigour owing to the recent release of the Steam Machine and upcoming release of the Steam Frame. In a new update for the Steam client, Valve introduced some new fixes and features for Remote Play, while also bringing in patches for Steam Input, the Steam overlay, the Workshop, and various other gubbins.
