"We continue to see very strong growth in PC Gaming, with Steam growing 50%
in the last 12 months," said Gabe Newell, Valve's president. "With these
announcements we hope that we are helping build on that momentum."
Steam Machines, Windows PCs, Macs, and Linux PCs will be able to take
advantage of a new product announced at GDC called Steam Link. Designed to
extend your Steam experience to any room in the house, Steam Link allows you
to stream all your Steam content from any PC or Steam Machine on the same
home network. Supporting 1080p at 60Hz with low latency, Steam Link will be
available this November for $49.99, and available with a Steam Controller for
an additional $49.99 in the US (worldwide pricing to be released closer to
launch).
Steam Machines from partners Alienware and Falcon Northwest are being shown,
with Machines from a dozen other partners slated to release this November.
Steam Machines will start at the same price point as game consoles, with
higher performance. Customers interested in the best possible gaming
experience can choose whichever components meet their needs. Epic will give a
demonstration of the newly announced Unreal Tournament running on a 4K
monitor driven by the Falcon Northwest Steam Machine. "We love this
platform," said Tim Sweeney, founder of Epic Games. "Whether you're running
incredibly detailed scenes at 4K or running 1080p at 120 FPS for an intense
shooter experience, this brings world-class gaming and graphics to
televisions with an open platform true to Valve's PC gaming roots."
Valve will show a virtual reality (VR) headset. Developer versions of the
headset will be available this spring, and partner HTC will ship their Vive
headset to consumers by the end of the year.
Two new technologies are part of the VR release - a room scale tracking
system codenamed Lighthouse, and a VR input system. "In order to have a high
quality VR experience, you need high resolution, high speed tracking," said
Valve's Alan Yates. "Lighthouse gives us the ability to do this for an
arbitrary number of targets at a low enough BOM cost that it can be
incorporated into TVs, monitors, headsets, input devices, or mobile devices."
Valve intends to make Lighthouse freely available to any hardware
manufacturers interested in the technology.
"Now that we have Lighthouse, we have an important piece of the puzzle for
tackling VR input devices," said Valve's Joe Ludwig. "The work on the Steam
Controller gave us the base to build upon, so now we have touch and motion as
integrated parts of the PC gaming experience."
"We've been working in VR for years and it was only until we used SteamVR's
controllers and experienced the magic of absolute tracking that we were able
to make the VR game we always wanted to make," said Alex Schwartz of
Owlchemylabs.
VR demos being shown at GDC include work from Bossa Studios, Cloudhead Games,
Dovetail Games, Fireproof Studios, Google, Owlchemylabs, Skillman & Hackett,
Steel Wool Games, Vertigo Games, and Wevr.
Valve announced the Source 2 engine, the successor to the Source engine used
in Valve's games since the launch of Counter-Strike: Source and Half-Life 2.
"The value of a platform like the PC is how much it increases the
productivity of those who use the platform. With Source 2, our focus is
increasing creator productivity. Given how important user generated content
is becoming, Source 2 is designed not for just the professional developer,
but enabling gamers themselves to participate in the creation and development
of their favorite games," said Valve's Jay Stelly. "We will be making Source
2 available for free to content developers. This combined with recent
announcements by Epic and Unity will help continue the PCs dominance as the
premiere content authoring platform."
Also as part of supporting PC gaming, Valve announced that it will be
releasing a Vulkan-compatible version of the Source 2 engine. Vulkan is a
cross-platform, cross-vendor 3D graphics API that allows game developers to
get the most out of the latest graphics hardware, and ensures hardware
developers that there is a consistent, low overhead method of taking
advantage of products. Vulkan, previously called Next Generation OpenGL, is
administered by the Khronos Group, along with other standards such as OpenCL,
OpenGL, and WebGL.
GDC 2015 will mark the 13th anniversary of Valve's first public announcement
of Steam, which has since become the leading platform for PC, Mac, and Linux
games and software. In the last year, Steam realized the addition of many new
services and features - including In-Home Streaming, Broadcasting, Music, and
user-created stores - as it grew to over 125 million active accounts
worldwide.

That's it for the official press release, we've compiled the highlights and
some additional information below.
Steam Link
The Steam Link seems to be a small computer that you can hook up to your TV
through HDMI. It has an Ethernet port so you can use Valve's in-home
streaming without hiccups. There's also three USB ports to send input back to
the PC you're streaming from. Steam Link will be available in November this
year for $49.99. Steam Link on the Steam Store.
Update: Valve removed it from the store, it might be back later.
Steam Machines
There will be a bunch of Steam Machines released in November by different
manufacturers. Even though specifications and price points of the actual
machines have probably changed significantly, we expect most of the
manufacturers announced by Valve during CES 2014 to be part of this.
Steam Controller
The Steam Controller will be released in November this year as well. It's
available separately for $49.99. International prices coming closer to
release.
Source 2
Source 2 will be free to all content developers. There will also be Vulkan
support in Source 2, we'll probably hear more about Vulkan (and Valve's
involvement) in the upcoming GDC talk. Valve have not mentioned
licensing/royalty costs yet.
VR
Valve have officially announced their "Lighthouse" room tracking system used
with the HTC Vive through two base stations. Valve says Lighthouse can be
integrated into a multitude of different hardware including televisions,
mobile phones, headsets and input devices. Alan Yates's weird "Chief
Pharologist" Twitter bio sure makes a lot of sense now.
Valve intends to make Lighthouse freely available to any hardware
manufacturers interested in the technology.
