NVIDIA Releases VRWorks Audio 1.0

GPUs are good at large bundles of related tasks, saving die area by tying several chunks of data together. This is commonly used for graphics, where screens have two-to-eight million (1080p to 4K) pixels, 3d models have thousands to millions of vertexes, and so forth. Each instruction is probably done hundreds, thousands, or millions of times, and so parallelism greatly helps with utilizing real-world matter to store and translate this data.

Audio is another area with a lot of parallelism. A second of audio has tens of thousands of sound pressure samples, but another huge advantage is that higher frequency sounds model pretty decently as rays, which can be traced. NVIDIA decided to repurpose their OptiX technology into calculating these rays. Beyond the architecture demo that you often see in global illumination demos, they also integrated it into an Unreal Tournament test map.

And now it’s been released, both as a standalone SDK and as an Unreal Engine 4.15 plug-in. I don’t know what its license specifically entails, because the source code requires logging into NVIDIA’s developer portal, but it looks like the plug-ins will be available to all users of supported engines.

The latest version of GeForce Experience, 3.6, adds video capture (including screenshots and live streaming) support for OpenGL and Vulkan games. The catalog of titles support by ShadowPlay, which I’m pretty sure NVIDIA wants to call Share now, despite referring to it by its old name in the blog post, now includes No Man’s Sky, DOOM, and Microsoft’s beloved OpenGL title: Minecraft.

The rest of the update focuses on tweaking a few interface elements, including its streaming panel, its video and screenshot upload panel, and its gallery. Access to the alternative graphics APIs was the clear headline-maker, however, opening the door to several large gaming groups, and potentially even more going forward.

GeForce Experience 3.6 is available now.

The Gigabyte Aorus GTX 1080 Ti Xtreme Edition 11G; worth the extra $50?

Gigabyte's Aorus branded GTX 1080 Ti Xtreme Edition 11G just arrived on our Hardware Leaderboard, not in small part due to this review at The Tech Report.  The card utilizes the same triple fans moving air over five copper heat pipes combined with a mess of fins and a large copper plate as the non-Ti Xtreme card we have seen previously.  That cooler allows the card to be clocked at 1632MHz base, 1746MHz Boost with memory hitting over 2.8GHz right out of the box and with Afterburner you can reach even higher.  TR's testing shows that this does have a noticeable effect on performance compared to the Founder's Edition cards.

"Aorus' GeForce GTX 1080 Ti Xtreme Edition 11G promises to unshackle the GP102 GPU from the constraints of a reference board. We run this card through our gauntlet of performance and noise testing to see whether it's worth the premium over Nvidia's GeForce GTX 1080 Ti Founders Edition."

GTC 17: NVIDIA Demos (Professional) Multi-User VR

Four Quadro P6000s installed in a single server, which looks like a 4U rack-mounted box, are shown running four HTC Vive Business Edition VR systems through virtual machines. It isn’t designed to be a shipping product, just a demo for NVIDIA’s GPU Technology Conference that was developed by their engineers, but that should get the attention of this trade show’s attendees, who are mostly enterprise-focused.

For context, this system has roughly equivalent GPU horsepower to four Titan Xps, albeit with twice the RAM and slightly different clocks; there’s plenty of power per headset to harness. Still, running this level of high-performance application on a virtual machine could be useful in a variety of business applications, from architectural visualization to, as NVIDIA notes, amusement parks.

Given that it’s just a proof-of-concept demo, you’ll need to build it yourself to get one. They didn’t mention using any special software, though.

AMD Releases Radeon Software Crimson ReLive 17.5.1

Subject: Graphics Cards | May 5, 2017 - 12:21 AM |
Tagged: amd, graphics drivers

Aligning with the release of Prey, AMD released the first Radeon Crimson ReLive graphics driver of the month: 17.5.1. This version optimizes the aforementioned title with up to a 4.7% boost in performance, versus 17.4.4 as measured on an RX 580, according to AMD. It also adds multi-GPU support to the title, for those who have multiple AMD graphics cards.

A bunch of bugs were also fixed in this release, as is almost always the case. Probably the most important one, though, is the patch to their auto-updater that prevents it from failing. They also fixed a couple issues with hybrid graphics, including a crash in Civilization VI with those types of systems.

You can pick up 17.5.1 from AMD’s website.

Prey The Fourth Be With You??? GeForce 382.05 Drivers

Tagged: nvidia, graphics drivers

If you’re cringing while reading that headline, then rest assured I felt just as dirty writing it.

NVIDIA has released another graphics driver, 382.05, to align with a few new game releases: Prey, Battlezone, and Gears of War 4’s latest update. The first title is a first-person action-adventure title by Arkane Studios, which releases tomorrow. Interestingly, the game runs on CryEngine... versus their internally-developed Void engine, as seen in Dishonored 2; Unreal Engine, as they’ve used with the original Dishonored; or id Tech, which Bethesda’s parent company, ZeniMax, owns through id Software and has a bit of a name-association with franchise that this Prey rebooted.

Cross-eyed yet? Good. Let’s move on.

Fans of Gears of War 4, specifically those who have multiple NVIDIA graphics cards, might be interested in SLI support for this DirectX 12-based title. As we’ve mentioned in the past, the process of load-balancing multiple GPUs has changed going from DirectX 11 to DirectX 12. According to The Coalition, SLI support was technically available on 381.89 (and 17.4.4 for AMD CrossFire), but NVIDIA is advertising it with 382.05. I’m not sure whether it’s a timing-based push, or if they optimized the experience since 381.89, but you should probably update regardless.

The driver also adds / updates the SLI profile for Sniper: Ghost Warrior 3 and Warhammer 40,000: Dawn of War III. A bunch of bugs have been fixed, too, such as “In a multi-display configuration, the extended displays are unable to enter sleep mode.” along with a couple of black and blue screen issues.

You can get them from GeForce Experience or NVIDIA’s website.

Benchmarking finessed Polaris, the XFX RX 580 8GB GTS Black Edition

Overclockers Club takes a look at XFX's new RX 580, inside and out as they completely removed the cooler to let you see all the parts.  The card does come overclocked right out of the box, however OCC pushed the card further, hitting 1440MHz on the GPU and 2116MHz for the memory.  That result fell short of the Powercolor Golden Sample card they tested but is still not bad, as XFX is not charging much of a premium over the reference model.  Pop by to see the full results.

"XFX's RX 580 8GB GTS Black Edition card is a factory overclocked card that uses a TrueClock OC of 1405MHz on the core right out of the gate with an OC+ core clock of 1425MHz possible. A total of 8GB of high speed GDDR5 memory is used to handle the textures to make 2560 x 1440 the new resolution target."

NVIDIA Releases GeForce 381.89 Drivers

Subject: Graphics Cards | April 28, 2017 - 09:02 PM |
Tagged: nvidia, graphics drivers

The latest Game Ready drivers from NVIDIA, 381.89, launched a couple of days before yesterday’s release of Warhammer 40,000: Dawn of War III. These drivers were the target of optimizations for that game, as well as Heroes of the Storm 2.0, Batman: Arkham VR, Rick and Morty: Virtual Rick-ality, and Wilson’s Heart.

Beyond game-specific optimizations, there isn’t a whole lot of difference between these and the previous drivers, 381.65. According to the release notes, the idle voltage has been reduced in some circumstances, a crash in Sniper Elite 3 has been resolved, and two bluescreens have been fixed. That said, there’s occasionally undocumented changes that crop up.

You can pick up these drivers from NVIDIA’s website, or through GeForce Experience.

AMD Releases Radeon Software Crimson ReLive 17.4.4

Subject: Graphics Cards | April 28, 2017 - 03:32 PM |
Tagged: amd, graphics drivers

The latest graphics driver from AMD, Radeon Software Crimson ReLive 17.4.4, aligns with yesterday’s release of Warhammer 40,000: Dawn of War III. They claim that, when the update is applied to an 8GB Radeon RX 580, users could see a performance gain of up-to 7% under certain conditions (when compared to 17.4.3).

amd-2016-crimson-relive-logo.png

The driver was re-released on April 27th, with the new installer no-longer adding a desktop shortcut to join the Quake Champions beta. I haven’t seen it personally, but OC3D claims that the shortcut pointed to a bit.ly link. I can see why users would be upset; AMD should have added an option in the installer that says something like, “Would you like to check out the Quake Champions beta? Yes, No, Create a Desktop Shortcut for Later” rather than just add stuff to the system. That said, a desktop shortcut is as benign as you can get, and I can also see why AMD wouldn’t think much of it.

That issue aside, the driver also fixes several bugs. One notable entry is, for users with an HDR-compatible display, Mass Effect: Andromeda will now display the correct colors under Windows 10 Creators Update. The most severe fix seems to be for RX 550 users, where the GPU would hard-lock a system after “long periods of time” since the last reboot. It sounds like those users should update to 17.4.4 as soon as convenient.

Radeon Software Crimson ReLive 17.4.4 is available at AMD’s website.
