NVIDIA APEX and UDK: Destruction Project

with one comment

Since March version of Unreal Development Kit, that has brought us NVIDIA APEX integration, users are playing with the new features trying to figure out their capabilities and limitations.

One of the most noticeable examples is this Destruction Project by the user named RU1NOUS. Even in current state it is demostrating nice a clean level design, good usage of general APEX Destruction features and interaction of APEX actors with tearable cloth objects.

Currently, APEX Destruction still requires a lot of work to make it really powerful and practical fracturing/destruction simulation tool, so let’s hope NVIDIA has all necessary additions on the roadmap.

We’ll try to keep the eye on RU1NOUS’s work and will update this post accordingly.

NVIDIA: PhysX continues to play an important role for us

with 8 comments

If you know PhysX only as GPU accelerated physics effects for PC games, lack of news and announcements of new GPU PhysX titles may give you an idea that NVIDIA has decided to drop support for PhysX completely. Forum threads like “Is PhysX Dead?” or “Physx dead?“, popping up from time to time, are indicating – users are worried.

We were able to contact NVIDIA and Mike Skolones, product manager for PhysX, has revealed us the company’s plans regarding PhysX Technology.

PhysXInfo.com: Is PhysX still playing important role for NVIDIA ? Are you planning to use and evolve the PhysX Technology over the years, or thinking about abandoning it in a favor for other solutions ?

Mike Skolones: PhysX has been and continues to play an important role for NVIDIA, as well as for the thousands of game developers who use PhysX for physics simulation across a broad range of platforms, including PC, Xbox360, PLAYSTATION 3, Nintendo Wii , iOS (including iPhone, iPod, and iPad), OSX, Linux, and Android (including NVIDIA Tegra™ devices), MMO servers running Linux and Windows; OSX ports; and Windows games, where GPU-accelerated advanced simulation is poised for continued growth.

Monster Madness - one of the fist games that utilizes PhysX SDK on Android platform

More importantly, because PhysX continues to be the choice of developers for integration into world’s leading commercial game engines, including Unreal Engine 3, Trinigy, Unity, Torque, Gamebryo, Lightspeed, Hero, and Dark Basic, not to mention other internal tech engines which also use PhysX, designers and artists know they have compelling development platforms they can immediately take advantage for making their games that much more realistic and interactive.

Deep Black is still targeting GPU PhysX support

without comments

It was looking that the Deep Black title (you may remember it as U-Wars, a project with a heavy fate itself) from russian developer Biart Studio is going to join the company of games with previously announced, but then abandoned GPU PhysX support (as example – Terminator: Salvation or Shattered Horizon).

Update: Despite all promises, final version of Deep Black does not support GPU PhysX.

However, in a recent interview to MGnews.ru, CEO of Biart Studio Konstantin Popov has stated that Deep Black will fully support hardware PhysX acceleration.

MGNews.ru: Tell us a little more about NVIDIA PhysX in PC version of the game. Will it add new interactive objects to the game or change behaviour of existing ones ? Will you support NVIDIA PhysX Technology on hardware level ?

Konstantin Popov: Yes, NVIDIA PhysX technology will be supported on hardware level. We are working tightly with NVIDIA on game optimization and adding new features. There are, of course,  physical objects and physical special effects. Moreover, popular stereoscopic technology – NVIDIA 3D Vision. We also support NVIDIA 3D Vision Surround.

Deep Black is a sci-fi third person shooter, promised to be packed with intense combat action – both on land and underwater. Target platforms are PC, Xbox 360 and PS3, with release date somewhere in 2011.

3ds Max 2012 released: new MassFX system overview

with 3 comments

If you were following Autodesk 3ds Max 2012 development process, you’ve already may know that built-in Havok Reactor physics simulation engine was replaced with a new MassFX unified simulation, using PhysX SDK integration.

However, since only mRigids solver (rigid body and joints dynamics) is available so far, one may say that Reactor was omitted too early, since not all the functionality (cloth, joint motors, forcefields, buoyancy) is present in MassFX currently.

Generally, MassFX is based on modified NVIDIA PhysX plug-in for 3ds Max (likely latest 2.60), and thus, resembles its basic functionality and interface, but several differences can be spotted:

  • Simulation in viewports runs much faster and smoother, thanks to new Nitrous graphics core. Performance Viewer tool, that can be found in PhysX plug-in 2.60, was removed.
  • APEX Clothing functionality is not available.
  • Dynamic ragdolls are not available.
  • Minor interface changes.

Note: MassFX does not support hardware acceleration currently.

Note #2: To avoid slowdowns while working with massive amount of objects, it is recommended to disable rendering of physical meshes (MassFX Toolbar > Display > Display Physical Meshes).

Previously, Autodesk has mentioned that future releases of MassFX will support cloth, softbody and ropes simulation, deformable meshes, fluids and forcefields.

Update: MassFX 2013 in review

Also, according to our knowledge, users will be able to install PhysX plug-ins from NVIDIA over MassFX, to enhance it with additional functionality.

APEX 1.1 will include APEX Turbulence, APEX 1.2 will add GPU Rigid bodies

with 7 comments

NVIDIA has prepared a “surprise” – fully upgraded and rewamped Developer Zone.

Among with full set of new features and content, PhysX section was renovated too (previously, certain parts were staying without update for years).

Browsing through new website, we have found some intersting data, never revealed before – for example, APEX FAQ states that:

What APEX modules are available?

APEX 1.1 will include Turbulence and APEX 1.2 will include APEX Destruction with GPU Rigid Bodies. If you are interested in Turbulence or Destruction with GPU rigid bodies, please email us at apex-beta@nvidia.com.

APEX 1.0 Beta was released to public several weeks ago.

Several updated pages we recommend you to visit:

How powerful must be a dedicated PhysX card ?

with 4 comments

Linus Tech Tips website has performed several benchmarks to find out if low-end dedicated PhysX cards are still valuable in systems with high-end graphics cards, using Mafia 2 benchmark.

8600 GTS GPU is clearly bottlenecking the whole system, resulting in lower fps than even a GTX 580, despite the fact that if single NVIDIA GPU is used in Mafia II, PhysX effects are partially running on CPU.

Cards Performance
GTX 580 + 8600 GTS 30.3 fps
GTX 580 49.7 fps
GTX 580 + GTX 580 57.5 fps
GTX 580 + GTX 550 Ti 56.6 fps
GTX 580 + GTX 560 Ti 55.3 fps

In conclusion, in case if you want to pair a dedicated PhysX card with GTX 580-class GPU, find a decent one – GTX 550 or “even something a little bit lower-end”, as author of this video recommends.
