As the first Oculus Rift retail units begin hitting hands in the US and abroad, both AMD and NVIDIA have released new drivers to help gamers ease into the world of VR gaming. 

Up first is AMD, with Radeon Software Crimson Edition 16.3.2. It adds support for Oculus SDK v1.3 and the Radeon Pro Duo...for all none of you that have that product in your hands. AMD claims that this driver will offer "the most stable and compatible driver for developing VR experiences on the Rift to-date." AMD tells us that the latest implementation of LiquidVR features in the software help the SDKs and VR games at release take better advantage of AMD Radeon GPUs. This includes capabilities like asynchronous shaders (which AMD thinks should be capitalized for some reason??) and Quick Response Queue (which I think refers to the ability to process without context change penalties) to help Oculus implement Asynchronous Timewarp.

NVIDIA's release is a bit more substantial, with GeForce Game Ready 364.72 WHQL drivers adding support for the Oculus Rift, HTC Vive and improvements for Dark Souls III, Killer Instinct, Paragon early access and even Quantum Break.

For the optimum experience when using the Oculus Rift, and when playing the thirty games launching alongside the headset, upgrade to today's VR-optimized Game Ready driver. Whether you're playing Chronos, Elite Dangerous, EVE: Valkyrie, or any of the other VR titles, you'll want our latest driver to minimize latency, improve performance, and add support for our newest VRWorks features that further enhance your experience.

Today's Game Ready driver also supports the HTC Vive Virtual Reality headset, which launches next week. As with the Oculus Rift, our new driver optimizes and improves the experience, and adds support for the latest Virtual Reality-enhancing technology.

Good to see both GPU vendors giving us new drivers for the release of the Oculus Rift...let's hope it pans out well and the response from the first buyers is positive!

Red matter and green blood; Vulkan runs on Linux

Last week AMD released a new GPU-PRO Beta driver stack and this Monday, NVIDIA released the 364.12 beta driver, both of which support Vulkan and meant that Phoronix had a lot of work to do.  Up for testing were the GTX 950, 960, 970, 980, and 980 Ti as well as the R9 Fury, 290 and 285.  Logically, they used the Talos Principal test, their results compare not only the cards but also the performance delta between OpenGL and Vulkan and finished up with several OpenGL benchmarks to see if there were any performance improvements from the new drivers.  The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.

"Thanks to AMD having released their new GPU-PRO "hybrid" Linux driver a few days ago, there is now Vulkan API support for Radeon GPU owners on Linux. This new AMD Linux driver holds much potential and the closed-source bits are now limited to user-space, among other benefits covered in dozens of Phoronix articles over recent months. With having this new driver in hand plus NVIDIA promoting their Vulkan support to the 364 Linux driver series, it's a great time for some benchmarking. Here are OpenGL and Vulkan atop Ubuntu 16.04 Linux for both AMD Radeon and NVIDIA GeForce graphics cards."

Going for Gold with MSI's newest GTX 980 Ti

Subject: Graphics Cards | March 18, 2016 - 05:59 PM |
Tagged: msi, GTX 980 Ti, MSI GTX 980 Ti GOLDEN Edition, nvidia, factory overclocked

Apart from the golden fan and HDMI port MSI's 980 Ti GOLDEN Edition also comes with a moderate factory overclock, 1140MHz Base, 1228MHz Boost and 7GHz memory, with an observed frequency of 1329MHz in game.  [H]ard|OCP managed to up those to 1290MHz Base and 1378MHz Boost and 7.8GHz memory with the card hitting 1504MHz in game.  That overclock produced noticeable results in many games and pushed it close to the performance of [H]'s overclocked MSI 980 Ti LIGHTNING.  The LIGHTNING proved to be the better card in terms of performance, both graphically and thermally, however it is also more expensive than the GOLDEN and does not have quite the same aesthetics, if that is important to you.

"Today we evaluate the MSI GTX 980 Ti GOLDEN Edition video card. This video card features a pure copper heatsink geared towards faster heat dissipation and better temps on air than other air cooled video cards. We will compare it to the MSI GTX 980 Ti LIGHTNING, placing the two video cards head to head in an overclocking shootout. "

Shedding a little light on Monday's announcement

Most of our readers should have some familiarity with GameWorks, which is a series of libraries and utilities that help game developers (and others) create software. While many hardware and platform vendors provide samples and frameworks, taking the brunt of the work required to solve complex problems, this is NVIDIA's branding for their suite of technologies. Their hope is that it pushes the industry forward, which in turn drives GPU sales as users see the benefits of upgrading.

nvidia-2016-gdc-gameworksmission.png

This release, GameWorks SDK 3.1, contains three complete features and two “beta” ones. We will start with the first three, each of which target a portion of the lighting and shadowing problem. The last two, which we will discuss at the end, are the experimental ones and fall under the blanket of physics and visual effects.

nvidia-2016-gdc-volumetriclighting-fallout.png

The first technology is Volumetric Lighting, which simulates the way light scatters off dust in the atmosphere. Game developers have been approximating this effect for a long time. In fact, I remember a particular section of Resident Evil 4 where you walk down a dim hallway that has light rays spilling in from the windows. Gamecube-era graphics could only do so much, though, and certain camera positions show that the effect was just a translucent, one-sided, decorative plane. It was a cheat that was hand-placed by a clever artist.

nvidia-2016-gdc-volumetriclighting-shaftswireframe.png

GameWorks' Volumetric Lighting goes after the same effect, but with a much different implementation. It looks at the generated shadow maps and, using hardware tessellation, extrudes geometry from the unshadowed portions toward the light. These little bits of geometry sum, depending on how deep the volume is, which translates into the required highlight. Also, since it's hardware tessellated, it probably has a smaller impact on performance because the GPU only needs to store enough information to generate the geometry, not store (and update) the geometry data for all possible light shafts themselves -- and it needs to store those shadow maps anyway.

nvidia-2016-gdc-volumetriclighting-shaftsfinal.png

Even though it seemed like this effect was independent of render method, since it basically just adds geometry to the scene, I asked whether it was locked to deferred rendering methods. NVIDIA said that it should be unrelated, as I suspected, which is good for VR. Forward rendering is easier to anti-alias, which makes the uneven pixel distribution (after lens distortion) appear more smooth.

Read on to see the other four technologies, and a little announcement about source access.

Rumor: NVIDIA's Next GPU Called GTX 1080, Uses GDDR5X

We are expecting news of the next NVIDIA graphics card this spring, and as usual whenever an announcement is imminent we have started seeing some rumors about the next GeForce card.

Pascal is the name we've all being hearing about, and along with this next-gen core we've been expecting HBM2 (second-gen High Bandwidth Memory). This makes today's rumor all the more interesting, as VideoCardz is reporting (via BenchLife) that a card called either the GTX 1080 or GTX 1800 will be announced, using the GP104 GPU core with 8GB of GDDR5X - and not HBM2.

The report also claims that NVIDIA CEO Jen-Hsun Huang will have an announcement for Pascal in April, which leads us to believe a shipping product based on Pascal is finally in the works. Taking in all of the information from the BenchLife report, VideoCardz has created this list to summarize the rumors (taken directly from the source link):

  • Pascal launch in April
  • GTX 1080/1800 launch in May 27th
  • GTX 1080/1800 has GP104 Pascal GPU
  • GTX 1080/1800 has 8GB GDDR5X memory
  • GTX 1080/1800 has one 8pin power connector
  • GTX 1080/1800 has 1x DVI, 1x HDMI, 2x DisplayPort
  • First Pascal board with HBM would be GP100 (Big Pascal)

Rumored GTX 1080 Specs (Credit: VideoCardz)

The alleged single 8-pin power connector with this GTX 1080 would place the power limit at 225W, though it could very well require less power. The GTX 980 is only a 165W part, with the GTX 980 Ti rated at 250W.

As always, only time will tell how accurate these rumors are; though VideoCardz points out "BenchLife stories are usually correct", though they are skeptical of the report based on the name GTX 1080 (though this would follow the current naming scheme of GeForce cards).

ZOTAC is teasing a new mini PC "ready for virtual reality" leading up to Cebit 2016, happening later this month. The ZBOX MAGNUS EN980 supplants the EN970 as the most powerful version of ZOTAC's gaming mini systems, and will come equipped with no less than an NVIDIA GeForce GTX 980.

Some questions remain ahead of a more formal announcemnent, and foremost among them is the version of the system's GTX 980. Is this the full desktop variant, or the GTX 980m? It seems to be the former, if we can read into the "factory-installed water-cooling solution", especially if that pertains to the GPU. In any case this will easily be the most powerful mini-PC ZOTAC has released, as even the current MAGNUS EN970 doesn't actually ship with a GTX 970 as the name would imply; rather, a GTX 960 handles discrete graphics duties according to the specs.

The MAGNUS EN980's GTX 980 GPU - mobile or not - will make this a formidable gaming system, paired as it is with a 6th-gen Intel Skylake CPU (the specific model was not mentioned in the press release; the current high-end EN970 with dicrete graphics uses the Intel Core i5-5200U). Other details include support for up to four displays via HDMI and DisplayPort, USB 3.0 and 3.1 Type-C inputs, and built-in 802.11ac wireless.

We'll have to wait until Cebit (which runs from March 14 - 18) for more details. Full press release after the break.

NVIDIA Pulls 364.47 WHQL and Releases 364.51 Beta

Subject: Graphics Cards | March 9, 2016 - 04:55 PM |
Tagged: nvidia, graphics drivers

The last couple of days were not too great for software patches. Microsoft released a Windows 10 update that breaks 5K monitors, and NVIDIA's driver bug, mentioned in the last post, was bigger than they realized. It turns out that the issue is not isolated to multiple monitors, but rather had something to do with choosing “Express Install” in the setup screen.

nvidia-2015-bandaid.png

In response, NVIDIA has removed 364.47 from their website. For those who want “Game Ready” drivers with games like “The Division,” NVIDIA has provided a 364.51 beta driver that supposedly corrects this issue. People on the forums still claim to have problems with this driver, but nothing has been confirmed yet. It's difficult to tell whether other issues exist with the drivers, whether users are having unrelated issues that are attributed to the drivers, or if it's just a few hoaxes. ((Update on March 9th @ 12:41pm: Still nothing confirmed, but one of our comments claim that they've experienced issues personally.)) If you are concerned, then you can roll back to 362.00.

Fortunately for me, I chose to clean install 364.47 and have not had any issues with them. I asked a representative from NVIDIA on Twitter whether I should upgrade to 364.51, and he said that a few other bugs were fixed but I shouldn't bother.

If you managed to properly install 364.47, then you should be fine staying there.

NVIDIA Releases 364.47 WHQL Drivers... with Vulkan

Subject: Graphics Cards | March 7, 2016 - 11:15 PM |
Tagged: vulkan, nvidia, graphics drivers, game ready

This new driver for NVIDIA brings Vulkan support to their current, supported branch. This is particularly interesting for me, because the Vulkan branch used to pre-date fixes for Adobe Creative Cloud, which meant that things like “Export As...” in Photoshop CC didn't work and After Effects CC would crash. They are also WHQL-certified, and they roll in all of the “Game Ready” fixes and optimizations that were released since ~October, which would be mostly new for Vulkan's branch.

... This is going to be annoying to temporarily disable...

Speaking of which, GeForce Game Ready 364.47 drivers is classified as “Game Ready” itself. The four titles optimized with this release are: Tom Clancy's The Division, Need For Speed, Hitman, and Ashes of the Singularity. If you are interested in playing those games, then this driver is what NVIDIA recommends that you use.

Note that an installation bug has been reported, however. When installing with multiple monitors, NVIDIA suggests that you disable all but one during the setup process, but you can safely re-enable them after. For me, with four monitors and a fairly meticulous desktop icon layout, this was highly annoying, but something I've had to deal with over time (especially the last two, beta Vulkan drivers). It's probably a good idea to close all applications and screenshot your icons before running the installer.

New ASUS GeForce GTX 950 2G Requires No PCIe Power

Subject: Graphics Cards | March 4, 2016 - 09:48 PM |

ASUS has released a new version of the GTX 950 called the GTX 950 2G, and the interesting part isn't what's been added, but what was taken away; namely, the PCIe power requirement.

gtx9502g_1.jpeg

When NVIDIA announced the GTX 950 (which Ryan reviewed here) it carried a TDP of 90W, which prevented it from running without a PCIe power connector. The GTX 950 was (seemingly) the replacement for the GTX 750, which didn't require anything beyond motherboard power via the PCIe slot, and the same held true for the more powerful GTX 750 Ti. Without the need for PCIe power that GTX 750 Ti became our (any many others) default recommendation to turn any PC into a gaming machine (an idea we just happened to cover in depth here).

Here's a look at the specs from ASUS for the GTX 950 2G:

  • Graphics Engine: NVIDIA GeForce GTX 950
  • Interface: PCI Express 3.0
  • Video Memory: GDDR5 2GB
  • CUDA Cores: 768
  • Memory Clock: 6610 MHz
  • Memory Interface: 128-bit
  • Engine Clock
    • Gaming Mode (Default) - GPU Boost Clock : 1190 MHZ , GPU Base Clock : 1026 MHz
    • OC Mode - GPU Boost Clock : 1228 MHZ , GPU Base Clock : 1051 MHz
  • Interface: HDMI 2.0, DisplayPort, DVI
  • Power Consumption: Up to 75W, no additional PCIe power required
  • Dimensions: 8.3 x 4.5 x 1.6 inches

Whether this model has any relation to the rumored "GTX 950 SE/LP" remains to be seen (and other than power, this card appears to have stock GTX 950 specs), but the option of adding in a GPU without concern over power requirements makes this a very attractive upgrade proposition for older builds or OEM PC's, depending on cost.

The full model number is ASUS GTX950-2G, and a listing is up on Amazon, though seemingly only a placeholder at the moment. (Link removed. The listing was apparently for an existing GTX 950 product.)
