NVIDIA Simultaneous Multi-Projection Explained

On May 6, NVIDIA revealed the first gaming GPU based on their new Pascal architecture – the NVIDIA GeForce GTX 1080. The GeForce GTX 1080 not only boasts the latest Pascal architecture, it is also fabricated on the new 16 nm FinFET process technology and uses the new GDDR5X memory.

Although we were not in Austin, Texas for the official launch, NVIDIA invited us to an exclusive tech briefing in Bangkok on May 20th. While these hardware specifications are well-known by now, this was a technical briefing that would give us greater insights into the other new technologies that are being introduced with the GeForce GTX 1080.

NVIDIA brought in the big guns for the tech briefing and demonstration – Nick Stam (NVIDIA Senior Technical Marketing Director), Jeff Yen (NVIDIA Senior Technical Marketing Manager) and John Gillooly (NVIDIA Technical Marketing Manager). We will be posting a series of videos of their presentations, divided into topic-specific chunks. Today, we are going to look at the new NVIDIA Simultaneous Multi-Projection Technology works.

NVIDIA Simultaneous Multi-Projection Explained

In this 19 minute-long video, Nick and Jeff explains how the new NVIDIA Simultaneous Multi-Projection technology will make a huge difference for gamers with multi-monitor setups, or virtual reality headsets. Both multi-monitor and virtual reality gamers will enjoy a much wider, and more realistic field of view.

On top of that, Simultaneous Multi-Projection can deliver up to 1.5X better pixel throughput, and 2X better geometry throughput for virtual reality displays! To find out how they do it, watch this video, or read the explainer below.

How Simultaneous Multi-Projection Delivers Better Performance

The new Simultaneous Multi-Projection architecture of the NVIDIA Pascal-based GPUs will be able to tackle two unique performance challenges that virtual reality creates – Lens Matched Shading and Single Pass Stereo.

Lens Matched Shading improves pixel shading performance by rendering closely to the warped dimensions of VR display output. This avoids rendering many pixels that would otherwise be discarded before the image is output to the VR headset.

Single Pass Stereo turbocharges geometry performance by drawing geometry only once, and then simultaneously projecting both right-eye and left-eye views of the geometry. This effectively halves the workload of traditional VR rendering, which requires the GPU to draw geometry twice — once for the left eye and once for the right eye.

Both techniques allow developers to increase performance and visual detail of their VR applications. Combined with the performance of GTX 1080 GPUs, Simultaneous Multi-Projection delivers a dramatic 2x VR performance improvement over the GeForce GTX TITAN X.

NVIDIA Ansel In-Game Screenshot Technology Explained

NVIDIA Ansel Explained

NVIDIA Ansel not just an in-game screenshot utility. It actually detaches you, the player, from the in-game limitations so you can capture your in-game shots in ways not possible before. You can also adjust the screenshots with a variety of post-process filters, or capture HDR images in super high resolution. You can even create 360-degree screenshots to display on your VR headset!

Here is a summary of NVIDIA Ansel’s key features :

Free Camera – Activating NVIDIA Ansel pauses the game and enables the Free Camera capability. This allows you to escape the first- or third-person perspective and compose your scene in any position, alignment or range, before taking unlimited high-resolution screenshots.

Super Resolution – Selecting the High Resolution option allows you to capture screenshots that are tens of thousands of pixels in size. This allows you to downsample the screenshot later, or zoom in to capture detail cannot be seen with the naked eye.

Post-Process Filters – NVIDIA Ansel comes with brightness, vignette, sketch, colour enhancer and special FX filters for added creativity. Users can even create and share their own special FX filters.

OpenEXR Capture – You can export Ansel screenshots in Industrial Light & Magic’s OpenEXR format so you can adjust the exposure, colour and levels in post-processing without creating artifacts.

360 Capture – This option allows you to create and share 360 degree screenshots for VR headsets.

NVIDIA brought in the big guns for the tech briefing and demonstration – Nick Stam (NVIDIA Senior Technical Marketing Director), Jeff Yen (NVIDIA Senior Technical Marketing Manager) and John Gillooly (NVIDIA Technical Marketing Manager). We will be posting a series of videos of their presentations, divided into topic-specific chunks, starting with this one on the NVIDIA GeForce GTX 1080’s key features.

GeForce GTX 1080 Key Features Explained

In this 19 minute video, Nick Stam talks about the five marvels of the new NVIDIA GeForce GTX 1080 graphics card. He showed just how much more powerful and efficient the GeForce GTX 1080 is compared to the previous Maxwell generation of GPUs.

For the technically-minded, Nick also delved into the specific optimisations in the NVIDIA Pascal GPU. Find out how they crafted it for a higher clock speed and Pascal’s new 4th generation delta colour compression technology. Check it out!

For your reference, here are the five marvels of NVIDIA Pascal :

Next-Gen GPU Architecture- Pascal is optimized for performance per watt. The GTX 1080 is 3x more power efficient than the Maxwell Architecture.
16nm FinFET Process- The GTX 1080 is the first gaming GPUs designed for the 16nm FinFET process, which uses smaller, faster transistors that can be packed together more densely. Its 7.2 billion transistors deliver a dramatic increase in performance and efficiency.
Advanced Memory- Pascal-based GPUs are the first to harness the power of 8GB of Micron’s GDDR5X memory. The 256-bit memory interface runs at 10Gb/sec., helping to drive 1.7x higher effective memory bandwidth than that delivered by regular GDDR5.
Superb Craftsmanship- Increases in bandwidth and power efficiency allow the GTX 1080 to run at clock speeds never before possible — over 1700 MHz — while consuming only 180 watts of power. New asynchronous compute advances improve efficiency and gaming performance. And new GPU Boost™ 3 technology supports advanced overclocking functionality.
Groundbreaking Gaming Technology- NVIDIA is changing the face of gaming from development to play to sharing. New NVIDIA VRWorks software features let game developers bring unprecedented immersiveness to gaming environments. NVIDIA’s Ansel™ technology lets gamers share their gaming experiences and explore gaming worlds in new ways.
