Ars Technica has firsthand impressions of Valve's upcoming game streaming
service, after checking out the invitation-only beta on
Steam. This streams
from another PC across your home network, so depending on your setup, this
involves less latency than cloud-based services. Since this involves playing a
game that resides on another machine in your same location, they do a little
explaining of why someone would want to do this:
Valve’s Linux-based
SteamOS has one big limitation compared with the full Steam experience: it can
only run games compatible with Linux. That limitation may be mostly put to rest
when a Steam Box is now paired with a Windows PC, allowing users to run any game
in the Steam library either natively in the Steam Box or streamed. The other key
benefit to the new streaming option is convenience. Graphically rich games often
suffer when run on thermally limited notebooks. Decoding a video stream requires
drastically less computing power than rendering a 3D environment, so gaming on a
modestly specced laptop could become much more satisfying.
