NVIDIA has released version 2.0.1 of GeForce Experience. This update does not bring many new features, hence why it is a third-level increment to the version number, but is probably worthwhile to download regardless. Its headlining feature is security enhancements with OpenSSL under remote GameStream on SHIELD. The update also claims to improve streaming quality and reduce audio latency.
While they do not seem to elaborate, I assume this is meant to fix Heartbleed, which is an exploit that allows an attacker to receive a small snapshot of active memory. If that is that case, it is unclear whether the SHIELD, the host PC during a game session, or both endpoints are affected.
The new GeForce Experience is available at the NVIDIA website. If it is running, it will also ask you to update it, of course.

NVIDIA unveiled the GeForce GTX TITAN Z at the GPU Technology Conference last month, and the cards will be for sale soon from various partners. ASUS will be one of the first AIB partners to offer a reference TITAN-Z.
The ASUS GTX TITAN Z pairs two full GK110-based GPUs with 12GB of GDDR5 memory. The graphics card houses a total of 5,760 CUDA cores, 480 texture manipulation units (TMUs), and 96 ROPs. Each GK110 GPU interfaces with 6GB of GDDR5 memory via a 384-bit bus. ASUS is using reference clockspeeds with this card, which means 705 MHz base and up to 876 MHz GPU Boost for the GPUs and 7.0 GHz for the memory.
For comparison, the dual-GPU TITAN Z is effectively two GTX TITAN Black cards on a single PCB. However, the TITAN Black runs at 889 MHz base and up to 980 MHz GPU Boost. A hybrid water cooling solution may have allowed NVIDIA to maintain the clockspeed advantage, but doing so would compromise the only advantage the TITAN Z has over using two (much cheaper) TITAN Blacks in a workstation or server: card density. A small hit in clockspeed will be a manageable sacrifice for the target market, I believe.
The ASUS GTX TITAN Z has a 375W TDP and is powered by two 8-pin PCI-E power connectors. The new flagship dual GPU NVIDIA card has an MSRP of $3,000 and should be available in early May.

Tagged: Mantle, amd
As our readers are well aware, Mantle is available for use with a few games. Its compatibility begun with the beta Catalyst 14.1 driver and an update for Battlefield 4. AMD was quite upfront about the technology, even granting a brief interview with Guennadi Riguer, Chief Architect of the API to fill in a few of the gaps left from their various keynote speeches.
What is under lock and key, however, is the actual software development kit (SDK). AMD claimed that it was too immature for the public. It was developed in partnership with DICE, Oxide Games, and other, established developers to fine-tune its shape, all the while making it more robust. That's fine. They have a development plan. There is nothing wrong with that. Today, while the SDK is still not public and sealed by non-disclosure agreement, AMD is accepting applications from developers who are requesting to enter the program.
If you want to develop a Mantle application or game, follow the instructions at their website for AMD to consider you. They consider it stable, performant, and functional enough for "a broader audience in the developer community".
AMD cites 40 developers already registered, up from seven (DICE, Crytek, Oxide, etc.).
If you are not a developer, then this news really did not mean too much to you -- except that progress is being made.

You need a bit of power for this
PC gamers. We do some dumb shit sometimes. Those on the outside looking in, forced to play on static hardware with fixed image quality and low expandability, turn up their noses and question why we do the things we do. It’s not an unfair reaction, they just don’t know what they are missing out on.
For example, what if you decided to upgrade your graphics hardware to improve performance and allow you to up the image quality on your games to unheard of levels? Rather than using a graphics configuration with performance found in a modern APU you could decide to run not one but FOUR discrete GPUs in a single machine. You could water cool them for optimal temperature and sound levels. This allows you to power not 1920x1080 (or 900p), not 2560x1400 but 4K gaming – 3840x2160.
All for the low, low price of $3000. Well, crap, I guess those console gamers have a right to question the sanity of SOME enthusiasts.
After the release of AMD’s latest flagship graphics card, the Radeon R9 295X2 8GB dual-GPU beast, our mind immediately started to wander to what magic could happen (and what might go wrong) if you combined a pair of them in a single system. Sure, two Hawaii GPUs running in tandem produced the “fastest gaming graphics card you can buy” but surely four GPUs would be even better.
The truth is though, that isn’t always the case. Multi-GPU is hard, just ask AMD or NVIDIA. The software and hardware demands placed on the driver team to coordinate data sharing, timing control, etc. are extremely high even when you are working with just two GPUs in series. Moving to three or four GPUs complicates the story even further and as a result it has been typical for us to note low performance scaling, increased frame time jitter and stutter and sometimes even complete incompatibility.
During our initial briefing covering the Radeon R9 295X2 with AMD there was a system photo that showed a pair of the cards inside a MAINGEAR box. As one of AMD’s biggest system builder partners, MAINGEAR and AMD were clearly insinuating that these configurations would be made available for those with the financial resources to pay for it. Even though we are talking about a very small subset of the PC gaming enthusiast base, these kinds of halo products are what bring PC gamers together to look and drool.
As it happens I was able to get a second R9 295X2 sample in our offices for a couple of quick days of testing.
Working with Kyle and Brent over at HardOCP, we decided to do some hardware sharing in order to give both outlets the ability to judge and measure Quad CrossFire independently. The results are impressive and awe inspiring.

GPU drivers have been a hot and sensitive topic at the site, especially recently, probably spurred on by the announcements of Mantle and DirectX 12. These two announcements admit and illuminate (like a Christmas tree) the limitations of APIs on gaming performance. Both AMD and NVIDIA have their recent successes and failures on their respective fronts. This will not deal with that, though. This is a straight round-up of new GPUs running the latest drivers... in Linux.
In all, NVIDIA tends to have better performance with its 700-series parts than equivalently-priced R7 or R9 products from AMD, especially in low-performance Source Engine titles such as Team Fortress 2. Sure, even the R7 260X was almost at 120 FPS, but the R9 290 was neck-and-neck with the GeForce GTX 760. The GeForce GTX 770, about $50 cheaper than the R9 290, had a healthy 10% lead over it.
In Unigine Heaven, however, the AMD R9 290 passed the NVIDIA GTX 770 by a small margin, coming right in line with it's aforementioned $50-bigger price tag. In that situation, where performance became non-trivial, AMD caught up (but did not beat). Also, third-party driver support is more embraced by AMD than NVIDIA. On the other hand, NVIDIA's proprietary drivers are demonstrably better, even if you would argue that the specific cases are trivial because of overkill.
And then there's Unvanquished, where AMD's R9 290 did not achieve triple-digit FPS scores despite the $250 GTX 760 getting 110 FPS.
Update: As pointed out in the comments, some games perform significantly better on the $130 R7 260X than the $175 GTX 750 Ti (HL2: Lost Coast, TF2, OpenArena, Unigine Sanctuary). Some other games are the opposite, with the 750 Ti holding a sizable lead over the R7 260X (Unigine Heaven and Unvanquished). Again, Linux performance is a grab bag between vendors.
There's a lot of things to consider, especially if you are getting into Linux gaming. I expect that it will be a hot topic, soon, as it picks up... ... Steam.

AMD has been taking PC gaming very seriously, especially over the last couple of years. While they have a dominant presence in the console space, with only IBM in opposition, I believe that direct licensing revenue was not their main goal, rather that they hope to see benefits carry over to the PC and maybe mobile spaces, eventually. In the PC space, Never Settle launched as a very successful marketing campaign. While it had a stutter with the launch of the R9 (and R7) product lines, it is back and is still called, "Never Settle Forever".
Keeping with Forever's alteration to the Never Settle formula, the type of card that you purchase yields a Gold, Silver, or Bronze reward. Gold (the R9 280 and R9 290 series, and the R9 295X2) gets three free games in the Gold tier, Silver (R9 270 and R7 260 series) gets two in the Silver tier, and Bronze (R7 250 and R7 240 series) gets one free game in the Bronze tier. By and large, the tiers are the same as last time plus a few old games and one upcoming Square Enix release: Murdered: Soul Suspect. They have also made deals with certain independent developers, where two indie titles bundled together count as one choice.
The complete breakdown of games is as follows:
|Murdered: Soul Suspect (June 3, 2014)||Yes||Yes||No|
|Dungeon Siege III||Yes||Yes||Yes|
|Company of Heroes 2||Yes||Yes||Yes|
|Total War: Shogun 2||Yes||Yes||Yes|
|Titan Quest (Gold Edition)||Yes||Yes||Yes|
|Supreme Commander (Gold Edition)||Yes||Yes||Yes|
|Deus Ex: Human Revolution||Yes||Yes||No|
|Just Cause 2||Yes||Yes||Yes|
|Banner Saga + Mutant Blobs Attack (indie combo)||Yes||Yes||Yes|
|Guacamelee + DYAD (indie combo)||Yes||Yes||Yes|
|Mutant Blobs Attack + DYAD (indie combo)||Yes||Yes||Yes|
|Banner Saga + DYAD (indie combo)||Yes||Yes||Yes|
|Mutant Blobs Attack + Guacamelee (indie combo)||Yes||Yes||Yes|
Oddly enough, there does not seem to be a Banner Saga + Guacamelee combo...
... the only impossible combination.
AMD has also announced that Never Settle will continue for more "additions" in 2014. Which ones? Who knows. It is clear that they have a great working relationship with Square Enix Europe, including basically their last six major titles in Never Settle and keeping them there, but there is not really anything from them on the horizon (at least, not announced). AMD does sound confident in having other deals lined up this year, however.
Never Settle Forever graphics cards are available now "at participating retailers". Bundle codes can be redeemed any time between now and August 31st.
There is some regional variance in game availability, however. Read up before you purchase (especially if you live in Japan). You should be fine if you live in North America, Europe, Middle East, Africa, New Zealand, Australia, and Latin America, though, at least where AMD products are available. Still, it is a good idea to check.
Competition is a Great Thing
While doing some testing with the AMD Athlon 5350 Kabini APU to determine it's flexibility as a low cost gaming platform, we decided to run a handful of tests to measure something else that is getting a lot of attention right now: AMD Mantle and NVIDIA's 337.50 driver.
Earlier this week I posted a story that looked at performance scaling of NVIDIA's new 337.50 beta driver compared to the previous 335.23 WHQL. The goal was to assess the DX11 efficiency improvements that the company stated it had been working on and implemented into this latest beta driver offering. In the end, we found some instances where games scaled by as much as 35% and 26% but other cases where there was little to no gain with the new driver. We looked at both single GPU and multi-GPU scenarios on mostly high end CPU hardware though.
Earlier in April I posted an article looking at Mantle, AMD's answer to a lower level API that is unique to its ecosystem, and how it scaled on various pieces of hardware on Battlefield 4. This was the first major game to implement Mantle and it remains the biggest name in the field. While we definitely saw some improvements in gaming experiences with Mantle there was work to be done when it comes to multi-GPU scaling and frame pacing.
Both parties in this debate were showing promise but obviously both were far from perfect.
While we were benchmarking the new AMD Athlon 5350 Kabini based APU, an incredibly low cost processor that Josh reviewed in April, it made sense to test out both Mantle and NVIDIA's 337.50 driver in an interesting side by side.
