Which Physics Acceleration Technology looks more promising ?

without comments

Expreview asked its readers recently, about which physics acceleration technology looks more promising to them.

Now, after 5 days and 281 votes, Nvidia PhysX is leading, Bullet is going second (probably, thanks to AMD users and all recent hype, as Bullet was listed as “AMD Bullet”, while being independent development),  Intel Havok comes third.

Polling is not over, so you still can lend your vote.

RayFire Tool 1.46 released

without comments

rayfire

Vadim Mir has updated RayFire Tool plug-in for 3ds Max to version 1.46. RayFire is focused on objects destruction simulation, and while supporting calculations via PhysX plug-in or Reactor, advanced features like interactive demolition or objects glueing are based on PhysX SDK only.

New in 1.46:

  • Wood splinters fragmentation type.
  • Deactivation of Animated Impact objects.
  • Interactive demolition by RF_Bomb.
  • Reduce keys function. More then 200 times faster then original max’s reducel keys function.

Some illustrations to RayFire capabilities:

pXent Pro PhysX wrapper and 3DGS: video

without comments

We’ve already wrote about pXent some time ago – that’s PhysX SDK wrapper for 3D GameStudio engine. Christian Kahler, pXent developer, has uploaded an interesting video today, showing that even complex PhysX SDK features like SPH-fluids, softbodies and cloth simulation can be easily implemented by one man.

Official Nvidia position on hybrid ATI+NV PhysX configurations

with 22 comments

Nvidia_logo

Back again on banned ATI+Nvidia PhysX configurations situation.  Initially, all the hype was based on e-mail from customer care support, while Nvidia official motives were undisclosed.  In order to bring some clarity, we’ve asked Nvidia for commentaries a while ago and finally recieved some answers:

PhysXInfo: Is it true that PhysX capabilities of NVIDIA GPUs and/or Ageia PPUs are disabled with newest drivers when a Non-NVIDIA (AMD) graphics card is present in the system?
Nvidia: It is true that running an NVIDIA GPU for PhysX with an AMD GPU for graphics is not a supported configuration. This mode was inadvertently turned on in a beta version of our Win7 drivers and on some older XP drivers. AMD does not support PhysX for their customers, and we don’t QA this configuration. With no QA, it is risky to run this configuration so we removed this capability in a recent driver release.

PhysXInfo: Can you please explain to us what factors have led to such decision?
Nvidia: Today NVIDIA’s GPU and PhysX drivers are interconnected to optimize performance. In the future we expect this interdependence to deepen. This alone makes it difficult to support a third party GPU.

In order to make sure our customers have a great experience, we QA every release of our PhysX or Graphics drivers by testing approximately 14 NVIDIA GPUs for graphics processing with 8 GPUs for PhysX processing on 6 common platforms with 6 OS’s using 6 combinations of CPU and memory. This is over 24000 possible configurations. While we don’t test every possible combination, it should be clear that the work and cost to NVIDIA is substantial. AMD does not support PhysX for their customers. Adding AMD GPUs would significantly increase the necessary work and cost for NVIDIA. We prefer to invest in inventing new technologies that give our customers great new experiences.

PhysX Hybrid Setup video proof: HD5870 + 8800GT

with one comment

OCteam.fr has prepared nice video, showcasing how hybrid PhysX configuration (ATI Radeon HD 5870 for graphics and Nvidia GeForce 8800GT for PhysX) is handling latest GPU PhysX games using drivers, modified by GenL. Surprisingly it’s working pretty well – Batman Arkham Asylum, Cryostasis, Mirror’s Edge, Star Tales, demos from PowerPacks, even badaboom transcoding are running without serious glitches.

Update: the way with modified drivers looks wrong to you ? Try to convince Nvidia by signing Returning PhysX to Nvidia customers petition.

PhysX Destruction Demo from GTC: video

with one comment

User dolesistheboss uploaded nice HD video, showcasing PhysX Destruction demo from Jen-Hsun Huang GTC keynote. Description says:

The goal was to try and construct a wall similar to how it may be constructed on a movie set and break it apart in a realistic manor in real-time. In this scenario we chose to throw ragdolls at it to fracture and splinter bits and pieces off.

The demo uses PhysX 2.8.3 and a beta release of APEX Destruction.

WeeklyTube Issue 5: PhysX video overview

without comments

While Batman Arkham Asylum PhysX boom is quiting down, videos from Nvidia GPU Technology Conference  are popping up. Most impressive, without doubt, was PhysX SPH Fluid demo which you can find here, but other videos we’ve found are also worth watching

Wall destruction demo from Jen-Hsun Huang keynote at GPU Technology Conference. You can find description and hi-res screens few posts earlier.

Nvidia GTC: Impressive new physx demo by PCGamesHardware

Another video from GTC keynote. In spite of encouraging title, it seems that shown effects are based on standart offline animation plug-ins like Fume FX or Realflow, but probably some realtime PhysX simulation is included as well.

Modded GeForce drivers: unlocked PhysX for Radeon ?

with 21 comments

It seems that some enthusiasts are trying to bypass ATI (for Graphics) + Nvidia (for PhysX) hybrid configurations blockage using modified drivers.

We’ll try to keep an eye on all developments and update this post accordingly.

Update #4: New 1.02 mod – now with 195.xx drivers and WinXP support – it’s recommended to prefer this one over 1.01 mod.

Probe #1: Modded 190.62 WinXP 32-bit drivers (useless)

Report: “Someone just took old files (from 185.68) and changed their resources and version info, to make it look similar to real 190.62. Needless to say, this doesn’t give you real 190.62 with all fixes and changes.”
GenL, NGOHQ forums.

Probe #2: PhysX Mod 1.01 x86 (not available) and PhysX Mod 1.01 x64 (not available) by GenL

(no support for 195.xx drivers currently)

NVIDIA GeForce driver 19x.xx PhysX mod [x86/x64] v1.01

* DESCRIPTION:
This mod will enable hardware PhysX support for NVIDIA GPU, when non-NVIDIA GPU
is used as a primary display device.
- intended only for WDDM 1.1 OS (Windows 7).
- only for multi-vendor multi-GPU configurations.

Mod discussion at NGOHQ forums.

Update: Video, showcasing this Mod in the work.

Update #2: Officical Nvidia position on hybrid ATI+NV PhysX configurations.

Update #3: How to set ATI+NV hybrid setup guide

Please use comments if you want to report certain driver’s efficiency/uselessness
