SIGGRAPH 2013: Latest improvements to Position Based Fluids

with 3 comments

Our readers may remember Position Based Fluids – new and promising fluid simulation approach, which has got quite a bit of attention few months ago.

Miles Macklin, one of the authors of the PB Fluids method, has presented latest improvements to the algorithm at SIGGRAPH 2013 conference – namely, two-way interaction with rigid bodies and cloth objects, as showcased in the videos below.

* Two-Way Coupling with Rigid Bodies

The Bureau: XCOM Declassified to have advanced Cloth and Particle PhysX effects

with 2 comments

Recent IGN Commentary video has revealed that PC version of “The Bureau: XCOM Declassified“, third-person shooter with tactical elements from 2K Games, will feature, among other improvements, the support for GPU accelerated PhysX effects.

Update: GPU PhysX effects trailer

As one can notice (at 1:30), the Advanced Graphics options menu of The Bureau includes “PhysX Particles” and “PhysX Cloth” settings, that can be switched On and Off separately.

According to information we have recieved so far, The Bureau: XCOM Declassified will be based on PhysX SDK 2.8.4 and Unreal Engine 3, and will feature not only particle (mesh debris) and cloth effects, but also use APEX Turbulence module.

PhysX SDK 3.3 Beta is available for public

with 3 comments

NVIDIA has released PhysX SDK 3.3 Beta 2 – first public Beta release of the new major version of the PhysX SDK 3.x

Update: PhysX SDK 3.3.0: Final Release

PhysX SDK 3.3 introduces a broad set of the new features and also presents a vast performance improvement.

Please refer for SDK 3.3 Beta Preview for the detailed description of some of the features, and for “The Evolution of the PhysX SDK” article for the performance data.

PhysX SDK 3.3 Beta 2 – Release Notes

RELEASE HIGHLIGHTS

  • Added PhysXDevice/64.dll to the PC packages. See Windows readme for more details.
  • Added support for the NVIDIA Kepler GPU architecture.
  • Added support for the Nintendo Wii U console.
  • Added support for Windows 8 Modern UI applications (ARM and x86).
  • Ported our SIMD library to the ARM NEON architecture.
  • Multi Box Pruning (MBP) is offered as an alternative broad phase algorithm to Sweep And Prune (SAP). MBP shows improved performance when all objects are moving or when inserting large numbers of objects. Its generic performance might be inferior to SAP when many objects are sleeping.
  • Significant performance and stability optimizations for rigid body solver.
  • New function to compute the minimum translational distance and direction to separate two overlapping geometry objects.
  • Improved Persisten Contact Manifold (PCM) contact generation mode is now often faster and more robust than the still available legacy path.
  • Improved performance of scene queries and contact reports.
  • Improved behavior and performance of Continuous Collision Detection (CCD).
  • Reduced memory footprint of rigid body classes.
  • Added support for sharing shapes among rigid bodies.
  • Significantly improved cloth behavior and GPU performance.
  • Added support for cloth colliding against itself, other cloth instances, and scene geometry.
  • Improved useability of binary and xml serialization.
  • Memory can be saved for objects that do not participate in the simulation and are used for scene queries only. For details see the new flag PxActorFlag::eDISABLE_SIMULATION.

PhysX System Software 9.13.0604

with 4 comments

nvidia-physx

And yet another PhysX System Software release – 9.13.0604 – has arrived with leaked 320.39 GPU Drivers.

Update#2: Official download

Update: 9.13.0604 release contains a fix for a bug, that was able to cause a crash in Metro: Last Light built-in benchmark. In addition, it resolves various installion bugs, that caused the installation to fail on some systems.

You can download PSS 9.13.0604 from our server (27 mb)

Thanks to Stefan for the link.

Batman: Arkham Origins will feature GPU PhysX effects as well

with 4 comments

More interesting news are coming from NVIDIA Press Event (Editor’s Day), which was held recently at E3 2013.

It is now confirmed that Batman: Arkahm Origins, third game in the award-winning Batman Saga, will support GPU accelerated PhysX effects.

Both Batman: Arkham Asylum and Batman: Arkham City are ones of the best games in the GPU PhysX pocket, so we hope that Arkham Origins will not dissapoint us as well.

The Witcher 3 will support GPU PhysX, now officially

with 4 comments

As the PhysX SDK and APEX integration was announced for The Witcher 3: Wild Hunt, new RPG title from CD Project Red, the only question was bothering us – will the game actually include hardware accelerated PhysX effects?

Finally, the following photo from the NVIDIA Editor’s Day presentation at E3, revealed recently by Igor Stanek, Head of NVIDIA EMEAI Tegra PR, is putting an end to the debate – The Witcher 3 will officially support GPU PhysX, along with other enhancements.

So far, we do not have any detailed information about PhysX SDK (we only assume that PhysX 3 will be used) integration or level GPU PhysX effects.

We can only say that “Fur and Hair”, mentioned in the slide, are related to actual physically simulated hair and fur technology (APEX Hair & Fur), presented previously.

Metro: Last Light PhysX Benchmarks roundup

without comments

PC version of recently released Metro: Last Light title features not only vivid DX11 based graphics, but also hardware accelerated PhysX effects.

In the following article we’ll try to gather the most reliable and accurate GPU PhysX benchmarks and tests for this game.

[14.05.2013] Metro Last Light – GPU Test by GameGPU

Sufficient amount of NVIDIA GPUs was tested in this article with the help of Metro’s built-in benchmark. However, since heavy graphics options (like SSAA) were used, it is hard to determine actual PhysX performance.

GPU PhysX in Metro: Last Light

with 5 comments

Metro: Last Light, a post-apocalyptic first person shooter with survival horror elements, is joining the family of PhysX enabled titles by offering a support for GPU accelerated physics effects.

Update: Metro Last Light PhysX Benchmarks roundup

Update #2: Metro: Last Light – GPU PhysX Profile

First game in the series – Metro 2033 – was also featuring a GPU PhysX content, however, it was limited to basic particle effects.

Was the Last Light able to improve the results of its predecessor? Let’s find out.

PhysX Research: Stable Stacking

without comments

An interesting “proof-of concept” demo was revealed today by Pierre Terdiman, senior software engineer in NVIDIA.

It is showcasing new CPU based algorithm, that will allow more effecient and stable simulation of large stacks.

Currently, PhysX SDK can utilize a feature (more like a “crude hack”) called “Adaptive Force” in order to improve stability of the stacks, but it also introduces some side-effects in certain cases.

As you can see on the picture above, 50-box-wide stack, simulated with the new algorithm, remains fully stable, while similar stacks, handled by any other current physics engine (PhysX SDKs/Bullet) collapse shortly.

Demo is also available for public download.

We hope that this new stacking solution will be included in PhysX SDK in the near future.

PhysX SDK and APEX now on Xbox One

with one comment

NVIDIA has announced that both PhysX SDK physics engine and APEX dynamics framework will offer support for next-generation Xbox One console from Microsoft.

“We are excited to extend our PhysX and APEX technologies to Microsoft’s Xbox One console”, said Mike Skolones, product manager for the PhysX SDK at NVIDIA.

“We look forward to the Xbox developer community taking advantage of PhysX and APEX along with Xbox One’s processing power, programmability and next-generation features to design cutting-edge games that deliver an unparalleled and ultra-realistic experience”

Earlier this year, it was also stated that PhysX SDK/APEX SDK will be available for Sony’s Playstation 4 console.

We assume that similar to PS4 case, PhysX for Xbox One will only use console’s CPU for physics calculations, at least at the beginning.
