GDC 15: Source 2 Is Free But Must Be Available on Steam

At the Game Developers Conference, Valve has formally announced the Source 2 engine and that it would be free for content developers. At the same time, they committed to releasing a version of it that is compatible with Vulkan, the graphics API from the Khronos Group that we have been talking about a lot over the last couple of days. Of course though, free can mean many things. As it turns out, there is one string attached: the game must be made available on Steam at launch. It can be available elsewhere too, but Steam must be one of the launch retailers.


I do wonder what will happen if someone makes a title that Steam refuses to publish. Of course, the natural thought is “What if Valve refuses to publish for content reasons?” That is an interesting thought, and maturity is one area that many other engines (like Unreal) do not restrict, but it is not the only concern (and Gabe Newell is quite laissez-faire with his -- albeit loosely defined -- content guidelines). What if your content simply does not make it on Steam? For instance, with is someone creates a title in Source 2 and has a failed attempt at Greenlight because it was unpopular? Are you then unable to publish your content through alternative channels, too? This seems like something that Valve will need to provide a little clarification on.

Try as I might, I could not find a release date for Source 2, however. It will arrive when it does.

Don't get too excited about this news, but AMD tells me that its next flagship Radeon R9 graphics card is up and running at GDC, powering an Oculus-based Epic "Showdown" demo.


Inside the box...

During my meeting with AMD today I was told that inside that little PC sits the "upcoming flagship Radeon R9 graphics card" but, of course, no other information was given. The following is an estimated transcript of the event:

Ryan: Can I see it?

AMD: No.

Ryan: I can't even take the side panel off it?

AMD: No.

Ryan. How can I know you're telling the truth then? Can I open up the driver or anything?

AMD: No.

Ryan: GPU-Z? Anything?

AMD: No.

Well, I tried.

Is this the rumored R9 390X with the integrated water cooler? Is it something else completely? AMD wouldn't even let me behind the system to look for a radiator so I'm afraid that is where my speculation will end.

Hooked up to the system was a Crescent Bay Oculus headset running the well-received Epic "Showdown" demo. The experience was smooth though of course there were no indications of frame rate, etc. while it was going on. After our discussion with AMD earlier in the week about its LiquidVR SDK, AMD is clearly taking the VR transition seriously. NVIDIA's GPUs might be dominating the show-floor demos but AMD wanted to be sure it wasn't left out of the discussion.

Can I just get this Fiji card already??

GDC 15: Intel and Raptr Partner for PC Gaming Optimization Software

One of NVIDIA's biggest achievements in the past two years has been the creation and improvement of GeForce Experience. The program started with one goal: to help PC gamers optimize game settings to match their hardware and make sure they are getting the top quality settings the hardware can handle and thus the best gaming experience. AMD followed suit shortly after with a partnership with Raptr, a company that crowd-sources data to achieve the same goal: great optimal game settings for all users of AMD hardware.

Today Intel is announcing a partnership with Raptr as well, bringing the same great feature set of Raptr to users of machines with Intel HD Graphics systems. High-end users might chuckle at the news but I actually think this feature is going to be more important for those gamers that utilize integrated graphics. Where GPU horsepower is at premium, compared to discrete graphics cards, using the in-game settings to get all available performance will likely result in the most improvement in experience of all the three major vendors.


Raptr will continue to include game streaming capability and it will also alert the users to when updated Intel graphics drivers are available - a very welcome change to how Intel distributes them.


Intel announced a partnership to deliver an even better gaming experience on Intel Graphics. Raptr, a leading PC gaming utility now available on Intel Graphics for the first time, delivers one-button customized optimizations that improve performance on existing hardware and the games being played, even older games. With just a little tweaking of their PC settings a user may be able to dial up the frame rate and details or even play a game they didn’t think possible.

The Raptr software scans the user’s PC and compares a given game’s performance across tens of millions of other gamers’ PCs, finding and applying the best settings for their Raptr Record system. And Raptr’s gameplay recording tools leverage the video encoding in Intel® Quick Sync technology to record and stream gameplay with virtually no impact on system performance. Driver updates are a snap too, more on Raptr for Intel available here.

Hopefully we'll see this application pre-installed on notebooks going forward (can't believe I'm saying that) but I'd like to see as many PC gamers as possible, even casual ones, get access to the best gaming experience their hardware can provide.

GDC 15: Intel Demos Socketed, LGA1150 Broadwell CPU with Iris Pro Graphics

Consumer have been asking for it since the first time Intel announced it, but Iris Pro graphics is finally finding its way to the desktop, socketed market. Shown powering one of Dell's new 5K displays, this processor shipping in "mid-2015", is going to be configured with a 65 watt TDP and will be unlocked for overclockers to tweak. Intel first disclosed these plans way back in May of 2014 so we are going to be approaching the 12-month mark for availability.


It doesn't look special, but this system has the first desktop Iris Pro processor

In a new disclosure at GDC, Intel showed the first 5th Generation Core LGA-socketed CPU with Intel® Iris™ Pro graphics. This 65 watt unlocked desktop processor, available mid-2015, will bring new levels of performance and power efficiency to Mini PCs and desktop All-In-Ones. Since 2006 the 3D performance of Intel Graphics has increased nearly 100 fold (Intel 3DMark06 measurements) and powerful form factors from Acer, Medion and Intel’s own NUCs are becoming available with 5th Generation Intel Core processors with Intel Iris Graphics.


Under that little heatsink...

Details of this new CPU offering, including clock speed and graphics performance, are still unknown but Intel claims we will have this part in our hands in the near future. This isn't targeted to overtake consumers with mid-range discrete graphics systems but instead will bring users interested in a SFF or low power system with both home theater features and improved gaming capability. Our testing with Iris Pro graphics in notebooks has proven that the gaming performance gains can be substantial, but often the battery life demands have limited implementations from OEMs. With a desktop part, we might actually be able to see the full capability of an integrated GPU with embedded memory.

GDC 15: Intel shows 3DMark API Overhead Test at Work

It's probably not a surprise to most that Futuremark is working on a new version of 3DMark around the release of DirectX 12. What might be new for you is that this version will include an API overhead test, used to evaluate a hardware configuration's ability to affect performance in Mantle, DX11 and DX12 APIs.


While we don't have any results quite yet (those are pending and should be very soon), Intel was showing the feature test running at an event at GDC tonight. In what looks like a simple cityscape being rendered over and over, the goal is to see how many draw calls, or how fast the CPU can react to a game engine, the API and hardware can be.

The test was being showcased on an Intel-powered notebook using a 5th Generation Core processor, code named Broadwell. Obviously this points to the upcoming support for DX12 (though obviously not Mantle) that Intel's integrated GPUs will provide.

It should be very interesting to see how much of an advantage DX12 offers over DX11, even on Intel's wide ranges of consumer and enthusiast processors.

GDC 15: PhysX Is Now Shared Source to UE4 Developers

Tagged: GDC, gdc 15, nvidia, epic games, ue4, unreal engine 4, PhysX, apex

NVIDIA and Epic Games have just announced that Unreal Engine 4 developers can view and modify the source of PhysX. This also includes the source for APEX, which is NVIDIA's cloth and destruction library. It does not include any of the other libraries that are under the GameWorks banner, but Unreal Engine 4 does not use them anyway.


This might even mean that good developers can write their own support for third-party platforms, like OpenCL. That would probably be a painful process, but it should be possible now. Of course, that support would only extend to their personal title, and anyone who they share their branch with.

If you are having trouble finding it, you will need to switch to a branch that has been updated to PhysX 3.3.3 with source, which is currently just “Master”. “Promoted” and earlier seem to be back at PhysX 3.3.2, which is still binary-only. It will probably take a few months to trickle down to an official release. If you are still unable to find it, even though you are on the “Master” branch, the path to NVIDIA's source code is: “Unreal Engine/Engine/Source/ThirdParty/PhysX/”. From there you can check out the various subdirectories for PhysX and APEX.

NVIDIA will be monitoring pull requests sent to that area of Unreal Engine. Enhancements might make it back upstream to PhysX proper, which would then be included in future versions of Unreal Engine and anywhere else that PhysX is used.

In other news, Unreal Engine 4 is now free of its subscription. The only time Epic will ask for money is when you ship a game and royalties are due. This is currently 5% of gross revenue, with the first $3000 (per product, per calendar quarter) exempt. This means that you can make legitimately free (no price, no ads, no subscription, no microtransactions, no Skylander figurines, etc.) game in UE4 for free now!

Valve has slowly but surely been working on its living room gaming initiative. Despite the slow progress (read: Valve time), Steam Machines are still a thing and a new bit of hardware called the “Steam Link” will allow you to stream all of your Steam content from your computers and Steam Machines to your TV over a local network. Slated for a November launch, the Steam Link is a $49.99 box that can be paired with a Steam Controller for another $49.99.

Valve has revealed little about the internals or specific features of the Steam Link. We do know that it can tap into Valve’s Steam In-Home Streaming technology to stream your PC games to your TV and output it at 1080p 60Hz (no word on specific latency numbers but the wired connection is promising). The box is tiny, looking to be less than half of a NUC (and much shorter) with sharp angles and one rounded corner hosting the Steam logo. Two USB ports, a Gigabit Ethernet port, a HDMI output, and an AC power jack sit on the rear of the device with a third USB port located on the left side of the Steam Link.

In all, the Steam Link looks like a promising device so long as Valve can get it out the door in time, especially with so many competing streaming technologies hitting the market. I’m looking forward to more details and getting my hands one later this year.

GDC 15: NVIDIA Shows TITAN X at Epic Games Keynote

For those of you worried that GDC would sneak by without any new information for NVIDIA's GeForce fans, Jen-Hsun Huang surprised everyone by showing up at the Epic Games' keynote with Tim Sweeny to hijack it.

The result: the first showing of the upcoming GeForce TITAN X based on the upcoming Maxwell GM200 GPU.


JHH stated that it would have a 12GB frame buffer and was built using 8 billion transistors! There wasn't much more information than that, but I was promised that the details would be revealed sooner rather than later.


Any guesses on performance or price?



Jen-Hsun signs the world's first TITAN X for Tim Sweeney.

Kite Demo running on TITAN X

UPDATE: I ran into the TITAN X again at the NVIDIA booth and was able to confirm a couple more things. First, the GPU will only require a 6+8-pin power connections, indicating that NVIDIA is still pushing power efficiency with GM200.


Also, as you would expect, the TITAN X will support 3-way and 4-way SLI, or at very least has the SLI bridges to support it.

Favor a steamier TV gaming experience? ZOTAC has announced a new Steam Machine on the eve of Valve’s presentation at GDC on Wednesday.


The SN970 presumably gets its name from the GTX 970M mobile GPU within, and this does the heavy lifting along with an unspecified 6th-generation Intel (Skylake) CPU. The massive amount of HDMI outputs (there are 4 HDMI 2.0 ports!) is pretty impressive for a small device like this, and dual Gigabit Ethernet ports are a premium feature as well.


There's a lot going on back here - the rear I/O of the ZOTAC SN970

Here's the rundown of features and specs from ZOTAC:

Key Features

  • SteamOS preloaded
  • NVIDIA GeForce® GTX 970M MXM graphics
  • 4 x HDMI 2.0, supports 4K UHD @ 60Hz

Finally, a SHIELD Console

NVIDIA is filling out the family of the SHIELD brand today with the announcement of SHIELD, a set-top box powered by the Tegra X1 processor. SHIELD will run Android TV and act as a game playing, multimedia watching, GRID streaming device. Selling for $199 and available in May of this year, there is a lot to discuss.

Odd naming scheme aside, the SHIELD looks to be an impressive little device, sitting on your home theater or desk and bringing a ton of connectivity and performance to your TV. Running Android TV means the SHIELD will have access to the entire library of Google Play media including music, movies and apps. SHIELD supports 4K video playback at 60 Hz thanks to an HDMI 2.0 connection and fully supports H.265/HEVC decode thanks to Tegra X1 processor.


Here is a full breakdown of the device's specifications.

  NVIDIA SHIELD Specifications
Processor NVIDIA® Tegra® X1 processor with 256-core Maxwell™ GPU with 3GB RAM
Video Features 4K Ultra-HD Ready with 4K playback and capture up to 60 fps (VP9, H265, H264)
Audio 7.1 and 5.1 surround sound pass through over HDMI
High-resolution audio playback up to 24-bit/192kHz over HDMI and USB
High-resolution audio upsample to 24-bit/192hHz over USB
Storage 16 GB
Wireless 802.11ac 2x2 MIMO 2.4 GHz and 5 GHz Wi-Fi
Bluetooth 4.1/BLE
Interfaces Gigabit Ethernet
HDMI 2.0
Two USB 3.0 (Type A)
Micro-USB 2.0
MicroSD slot (supports 128GB cards)
IR Receiver (compatible with Logitech Harmony)
Gaming Features NVIDIA GRID™ streaming service
NVIDIA GameStream™
SW Updates SHIELD software upgrades directly from NVIDIA
Power 40W power adapter
Weight and Size Weight: 23oz / 654g
Height: 5.1in / 130mm
Width: 8.3in / 210mm
Depth: 1.0in / 25mm
OS Android TV™, Google Cast™ Ready
Bundled Apps PLEX
NVIDIA SHIELD controller
HDMI cable (High Speed), USB cable (Micro-USB to USB)
Power adapter (Includes plugs for North America, Europe, UK)
Requirements TV with HDMI input, Internet access
Options SHIELD controller, SHIELD remove, SHIELD stand

Obviously the most important feature is the Tegra X1 SoC, built on an 8-core 64-bit ARM processor and a 256 CUDA Core Maxwell architecture GPU. This gives the SHIELD set-top more performance than basically any other mobile part on the market, and demos showing Doom 3 and Crysis 3 running natively on the hardware drive the point home. With integrated HEVC decode support the console is the first Android TV device to offer the support for 4K video content at 60 FPS.

Even though storage is only coming in at 16GB, the inclusion of an MicroSD card slot enabled expansion to as much as 128GB more for content and local games.


The first choice for networking will be the Gigabit Ethernet port, but the 2x2 dual-band 802.11ac wireless controller means that even those of us that don't have hardwired Internet going to our TV will be able to utilize all the performance and features of SHIELD.
