Valve’s Remote Play feature has always been one of Steam’s most useful tricks, but it has also carried the usual baggage that comes with game streaming. A single DIY coder found a way to make it feel snappier on local networks, and that work is now showing up in Valve’s own beta build. The result is a sharper look at how much better Steam streaming can feel when latency stops getting in the way.
Remote Play lets games run on one device and stream to another, whether that means a phone, tablet, TV, or handheld. It is a handy setup for playing across a home network, but the same process that makes it convenient can also introduce lag, which is the enemy of fast, responsive gameplay. Input delay, visual stutter, and compression artifacts can all chip away at the experience in a hurry.
That frustration pushed one coder to build something better. The new codec, Pyrowave, was created by Hans-Kristian Arntzen, also known online as TheMaister, and Valve has now added it to a beta version of Steam’s Remote Play system. It is a rare case where a single person’s side project ends up influencing a major platform feature.
Pyrowave’s main goal is simple: reduce streaming latency as much as possible on a local network. According to Valve employee slouken, the codec does that by streamlining the video encoding process, which helps the image arrive faster and with less of the mushy compression that can plague streamed games. It also leans on the PC’s GPU for encoding and decoding, which keeps the stream closer to native-looking quality.
That tighter encoding also brings a few extra benefits. Colors can be handled with more precision, and HDR support opens the door to richer brightness and contrast when the rest of the setup can take advantage of it. For players who care about image quality as much as speed, that combination is hard to ignore.
There is, of course, a catch, and it is a big one. Pyrowave is far hungrier for bandwidth than the usual Remote Play codecs, using roughly 5 to 10 times more data. Valve says it needs at least 100 Mbps to work properly, which puts it squarely in the territory of solid home networking rather than casual, thin connections.
That makes the feature a bit of a specialist tool instead of a universal upgrade. Valve recommends it mainly for setups where two PCs are connected through a router with Gigabit Ethernet, because that kind of local network can handle the extra load without sweating. On that sort of connection, bandwidth can be spent on quality instead of being hoarded just to keep the stream alive.
The tradeoff is pretty clear. Traditional codecs are easier on bandwidth, but they also tend to cost more in latency and image fidelity, which is exactly what Pyrowave is trying to fix. For a home network with enough muscle, the new codec could make Remote Play feel far more immediate, especially in games where timing and visual clarity matter most.
Steam users who want to try it can do so through the experimental SteamRT3 client option in system settings. That makes Pyrowave less of a future promise and more of a live test case, with Valve now putting a community-built idea into official circulation. It is the kind of move that shows just how much room there still is to improve streaming, even inside a platform as mature as Steam.
