NVIDIA Announces PhysX 4.0: Open Source (3-Clause BSD)!

Subject: General Tech | December 3, 2018 - 08:46 PM |
Tagged: pc gaming, PhysX, nvidia, physx 4.0, Unity, unreal engine 4

NVIDIA has just announced a new major version to their popular physics middleware: PhysX 4.0. They also announced that it (both 4.0 and 3.4) will be re-licensed as 3-line BSD. In terms of open-source licenses, this is about a permissive as you can get. You are basically free to do whatever you want – commercial, modified, unmodified, whatever – if you follow the guidelines (which are things like “no warranty”, “don’t sue us for liability”, “give us credit by leaving a copy of the license in all binary and source releases”, and “we’re not endorsing your product so don’t pretend that we are”).

For gamers? It will take a little while before this comes around to you. Unity is currently preparing to update to PhysX 3.4 with their upcoming 2018.3 release; that was the first major PhysX update since Unity 5.0 upgraded from PhysX 2.x to PhysX 3.3 back in March 2015. Epic Games seems to be a little quicker to update to a new PhysX version, but there’s nothing announced on their side either as far as I can tell.

On the technical side: this release of PhysX is interesting.

As mentioned, Unity 5.0 was the point when their PhysX implementation jumped from 2.x to 3.3. This was not a clean transition. NVIDIA changed the way that many of their solvers worked, making them much faster but also less stable (as in simulation stability – so, like, oscillating and breaking apart). While this was acceptable (because most simulations are cosmetic and, if it mattered, you had more performance to just increase the physics tick-rate to compensate) it upset developers who relied upon the stability of PhysX 2, forcing them to work around the glitches.

According to NVIDIA’s promotional video, this version is both more stable and faster. This means that it should be less work to setup things like ragdolls and ball-and-chain systems, while also supposedly being faster. In terms of stability, they intentionally showed a simulation of three balls and chains with varying masses. In PhysX 3.x, this tends to be a degenerate case where joints freak out and split (unless you compensate with smaller physics time steps). Even if it’s on-par with PhysX 3.x, this is a huge win for indie game developers.

PhysX 4.0 will be available for developers on December 20th. It’s unclear when any given engine will integrate it, however.

NVIDIA's new T-Rex; hopefully not a flaming dinosaur

Subject: General Tech | December 3, 2018 - 02:36 PM |
Tagged: nvidia, rtx, rtx titan, turing

The new Titan has arrived for the RTX generation and the specs are as impressive as the $2500 price tag.

  • 576 multi-precision Turing Tensor Cores, providing up to 130 teraflops of deep learning performance.
  • 72 Turing RT Cores, delivering up to 11 GigaRays per second of real-time ray-tracing performance.
  • 24GB of high-speed GDDR6 memory with 672GB/s of bandwidth — 2x the memory of previous-generation TITAN GPUs — to fit larger models and datasets.
  • 100GB/s NVIDIA NVLink can pair two TITAN RTX GPUs to scale memory and compute.
  • Incredible performance and memory bandwidth for real-time 8K video editing.
  • VirtualLink port provides the performance and connectivity required by next-gen VR headsets.

From what The Inquirer saw over a weekend of YouTubing, the card sports a gold-coloured shroud, and requires two eight-pin PCIe power connectors.  As of yet we don't have any benchmarks to show how it performs but from the sounds of the PR this will be of more use to content creators than gamers.  However, that is unlikely to stop some from trying it out; stay tuned for more.

"The Titan RTX, dubbed fondly by Nvidia as 'T-Rex', is based on the same Turing architecture as the firm's RTX 2070, 2080 and bork-prone 2080 Ti GPUs, equipping it with 130 teraflops of deep learning performance and 11 GigaRays of ray-tracing performance. "

NVIDIA Introduces AI Interactive Graphics Research: 3D from Real-World Video

Subject: General Tech | December 3, 2018 - 08:00 AM |
Tagged: ue4, nvidia, NeurIPS, deep learning, ai, 3D rendering

NVIDIA has introduced new research at the NeurIPS AI conference in Montreal that allows rendering of 3D environments from models trained on real-world videos. It's a complex topic that does have potential beyond scientific research with possible application for game developers, though this is not to the "product" stage just yet. A video accompanying the press release today shows how the researchers have implemented this technology so far:

AI_research_side-by-side_FINAL.JPG

"Company researchers used a neural network to apply visual elements from existing videos to new 3D environments. Currently, every object in a virtual world needs to be modeled. The NVIDIA research uses models trained from video to render buildings, trees, vehicles and objects."

The AI-generated city of a simple driving game demo shown at the NeurIPS AI conference gives us an early look at the sort of 3D environment that can be rendered by the neural network, as "the generative neural network learned to model the appearance of the world, including lighting, materials and their dynamics" from video footage, and this was rendered as the game environment using Unreal Engine 4.

"The technology offers the potential to quickly create virtual worlds for gaming, automotive, architecture, robotics or virtual reality. The network can, for example, generate interactive scenes based on real-world locations or show consumers dancing like their favorite pop stars."

Beyond video-to-video this research can also be applied to still images, with models providing the basis for what is eventually rendered movement (the video embedded above includes a demonstration of this aspect of the research - and yes, dancing is involved). And while all of this might be a year or two away from appearing in a new game release, but the possibilities are fascinating to contemplate, to say the least.

The RTX 2060 is leaking, not smoking

Subject: General Tech | November 23, 2018 - 12:55 PM |
Tagged: RTX 2060, rumour, nvidia

There were some interesting Final Fantasy XV benchmarks spotted recently, which seem to feature the unreleased RTX 2060.  The benchmark produced a score of 2,589 running on high quality at 4K resolution, which is a noticeable jump over the GTX 1060 as well as the new RX 590 from AMD, but not quite up to par with an unspecified RX Vega card which is likely the Vega 64.  The Inquirer wasn't able to find out much more unfortunately; we aren't even sure it will be branded RTX.

There are also some deals down below which are being updated throughout the day, if you are in a shopping mood.

"Still, before you go binning your last-gen Nvidia GPU, it's worth noting that the RTX 2060 used in the benchmark was likely an engineering sample, so the results will no doubt differ by the time it becomes official."

The other RTX feature, Content Adaptive Shading by Terror Billy

Subject: Graphics Cards | November 20, 2018 - 03:24 PM |
Tagged: wolfenstein 2: The New Colossus, turing, nvidia, content adaptive shading, CAS

Ray tracing gets most of the attention when one of NVIDIA's RTX cards is reviewed, and rightfully so but it is not the only new feature these cards bring to the table.  Content Adaptive Shading is one type of Variable Rate Shading, or VRS, which allows a Turing card to divide a screen into groups of pixels and then focus the application of shading to those groups which require it the most, spending processing time on shading areas which do not. 

The Tech Report delves into this topic in more depth, as well as showing off what it does to one of the few games which currently support it.  See just how The New Colossus is improved by CAS in this article.

"While Nvidia's RTX ray-tracing stack may be getting all the press, the Turing architecture has plenty of other tricks up its sleeve. One of these is called variable-rate shading, and its capabilities lay the foundation for a technique called content-adaptive shading. We tested what this tech can do for the performance of Wolfenstein II: The New Colossus."

One EVGA GeForce RTX 2080 Ti XC Allegedly Catches Fire

Subject: Graphics Cards | November 16, 2018 - 03:04 PM |
Tagged: RTX 2080 Ti, rtx, nvidia, geforce, fire, evga, 2080 Ti

On HardForums, there was a report (with several photos) of an EVGA GeForce RTX 2080 Ti that abruptly caught fire and, as you might expect, stopped working. It turns out that the damage is reasonably localized, so Allyn and I compared those photos with ones from an xDevs teardown in hopes to pinpoint the most likely component. We did not have that specific card in the office.

Again, this is just our best guess from images over the course of about a half hour.

We marked the center of carnage with a red X on both images, which correspond to opposite sides of the PCB. As you can tell… there’s not much there. On the one side, there is an R005 resistor and what looks like two small capacitors. Capacitors, which store energy like batteries, can explode, but they look to be too small to have caused that damage. On the other side, there are a pair of 1R0 1818 inductors, another component that appears to be a capacitor, and four metal solder pads.

Our current best guess, and it’s just a guess, is that something overloaded the card (such as a shorted power phase elsewhere on the card) and that section just happened to be the part that lit up like a fuse. It wasn’t as cut and dry as we were hoping from the start (such as if we saw a giant capacitor with nothing around it) but it doesn’t look like, as some sites are saying, that the VRAM overheated or that the GPU die was defective.

Hey Fatboy, way to take on that GTX 1060!

Subject: Graphics Cards | November 15, 2018 - 01:37 PM |
Tagged: amd, gtx 1060, nvidia, Polaris, rx 590

AMD released an interesting update to the RX 580 today, the aptly named RX 590.  It sports the same internals as the current card, with one significant difference which are the clocks.  The new RX 590 sports frequencies of 1469 MHz Base, 1545 MHz Boost which is a hair over 200MHz higher than the 580 and [H]ard|OCP were able to push it up to 1670MHz with a bit of extra juice.  Their findings matched Ken's, in that this new card makes NVIDIA's GTX 1060 obsolete as it outperforms it and at a better price point.  The only drawback to the XFX Fatboy model reviewed is given away in the name; the card is a wee bit over 2 slots in height.

[H]'s suite of games incorporates different titles than ours so make sure you do pay them a visit.

"AMD is launching the new Radeon RX 590 GPU today, and we have a custom XFX Radeon RX 590 Fatboy OC+ video card to evaluate. With a high factory overclock, and potential for overclocking, we will compare this video card with the EVGA GTX 1060 SSC overclocked and test at 1080p and 1440p gaming."
