New version of PhysX System Software is available. It contains bug fixes for recently released GPU PhysX games and provides support for 6xx GPUs.

• Includes the latest PhysX runtime builds to support all released PhysX content.
• Changes & fixed issues in this release
  • Fixed a bug that caused cloth (paper) to jitter in Batman Arkham City.
  • Updated SDKs for Alice 2 and other 2.8.4 applications.
• Supports NVIDIA PhysX acceleration on all GeForce 8-series, 9-series, 100-series, 200-series, 300-series, 400-series, 500-series, and 600-series GPUs with a minimum of 256MB dedicated graphics memory.

You can download PhysX System Software 9.11.1111 from NVIDIA website.

NVIDIA has uploaded new 9.11.1107 version of PhysX System Software.

Official description does not provide any details about new features in this release (only support for “500-series GPUs” was mentioned – this is not new), but we have spotted updated .dlls (.41) for PhysX SDK 2.8.3 and additional PhysXCore.dll for SDK 2.8.4.6 in a separate folder. Apparently, there are some other minor bugfixes.

Also, PSS 9.11.1107 is included in new 285.79 Beta GPU Drivers (upd: actually, mentioned, but not included).

PhysX System Software 9.11.1107 is available for download from NVIDIA website.

Upd: According to several user reports, this PSS is working fine with Hybrid PhysX and mod 1.05ff.

Since PhysX SDK was made driverless (SDK 2.8.4 and above) we have thought that PhysX System Software has become a history – latest version, 9.10.0514 was released about 10 month ago.

However, our fellow reader Stefan has provided us today with a link to a new PhysX System Software 9.11.0621, that he has extracted from DELL OEM drivers.

Update: Also, 9.11.0621 PSS is now provided officially with 285.27 GPU Drivers

Update #3: PhysX System Software 9.11.1107

We have not found anything particular new (no new/updated PhysX engine .dlls, only PhysXDevice and cudart* files are dated June 21 2011) in this release and since this driver is not fully offical – we recommend to install and/or use it at your own risk.

Update: Changes & fixed issues in this release

• Corrects Installer bugs for numerous locales

Owners of original Ageia PhysX cards are not in love these days – PPUs are not only not recognized by PhysX SDK 2.8.3/8.4, but even not supported by more or less recent PhysX System Software.

However, our reader Andrew “MohawkADE” Elliott has discovered a way (through drivers mixing, registry editing and some alchemy) to re-enable PPU support even with newest PhysX Drivers.

In this case you’re be able to kept your PPU in the system, benifit from hardware acceleration in PPU PhysX games and, potentially, in CPU PhysX titles, or even pair your PPU with dedicated Nvidia GPU.

Head over to our forums for further instructions.

New PhysX System Software v. 9.10.0514 (timestamp – 31.08.2010) has appeared on the web as part of leaked 260.52 GPU drivers and official 260.63 Beta drivers.

Current release notes are unknown.

Newest PhysX SDK 2.8.4.2 is ready for public beta testing – this is last and most stable current generation SDK, next one is going to be 3.0.

In addition, SDK 2.8.4. will be used as basis for upcoming APEX 1.0 toolset.

[18.08.10] Update: Release notes were supplemented with “driverless” mode description.

[19.08.10] Update #2: bug in the PhysXLoader code, that was preventing it from loading the local DLLs in 2.8.4, is now fixed. Replace the PhysXLoader.dll and PhysXLoader64.dll in your SDK installation with the new files from the archive “2.8.4_Loader_patch.rar“, found in the 2.8.4 folder on the developer download site.

[20.08.10] Update #3: PhysX SDK 2.8.4.3 with fixed PhysXLoader .dlls and included (previously missing) PhysXDevice.dll – is ready.

Currently, binary builds are available for 32- and 64-bit PC Windows, and Xbox 360

RELEASE NOTES:

General

• Removed PhysX Loader source code from source distribution. THIS WILL BE REVERTED FOR RELEASE. PhysXLoader code will be supplied to source licensees.
• Discontinued the Training Programs.
• Added source code of NxTetra (tet-maker) utility to source distribution.
• Removed spin waits from sample code.
• Added API to permit the user to specify the order in which compartments are simulated.
• Added compression limits to cloth.
• Cloth simulation no longer performs prediction for kinematic rigid bodies for improved interaction behavior.
• New driverless loader option for PC CPU distribution. In 2.8.4, application developers must ship PhysXCore.dll, PhysXCooking.dll, the cudarXX_XX_X.dll and physxdevice.dll with the application ‘locally’, in the directory where the .exe is located:

1. The application requests PhysXCore or PhysXCooking (v 2.8.4) from the PhysXLoader.

2. PhysXLoader searches for another DLL called ‘PhysXUpdateLoader’.

3. If PhysXUpdateLoader is not found, PhysXLoader will load the local PhysXCore or PhysXCooking.

4. If PhysXUpdateLoader is found, it looks for an updated replacement for the PhysXCore or PhysXCooking dlls.

5. If PhysXUpdateLoader cannot find the specified replacement DLL, PhysXLoader will load the local PhysXCore or PhysXCooking dlls.

6. If PhysXUpdateLoader can find the replacement DLLs, these will be loaded in place of the local PhysCore or PhysXCooking dlls.

7. The net result is that the developer has more control over the game installation process, doesn't have to worry about shipping a large System Software with the game, doesn't have to worry that the player will break his System Software somehow, etc.

Nvidia has revealed new PhysX System Software package – 9.10.0513

According to release notes, main difference from previous PhysX drivers is

• Bug fixes for Mafia 2

You can download 9.10.0513 PSS from here

Nvidia has revealed new PhysX System Software 9.10.0224. Main difference from 9.10.0223 System Software is:

• Fixes a bug that prevented PhysX from being accelerated on Optimus PCs.

You can download PhysX System Software 9.10.0224 from our server (34 mb – download currently unavailable)

Also, it seems that naming sheme has changed completely – from dates to version numbers of some kind.

Recent whql release of GeForce/ION 257.21 GPU drivers has brought us updated PhysX System Software v. 9.10.0223.

If naming sheme is still following same pattern, .0223 drivers are dated just day after previous 9.10.0222 System Software, and their feature set is also unknown currently (at least, SDK .dlls haven’t changed).

Update: System Software 9.10.0223 is now available for official download

• Bug fixes for Metro 2033 in SDKs version 2.8.3.
• Clothing bug fix in SDKs version 2.8.3 with respect to max distance clamping.
• GPU PhysX Performance optimizations for GeForce 400-series GPUs in all GPU PhysX enabled SDKs versions.
• Better error handling for GPU PhysX in the unlikely event of a CUDA error in SDKs version 2.8.3.
• Other miscellaneous bug fixes.

Today, Nvidia has presented new 256 Family of GeForce/ION drivers. Among from other features, like improved performance for GTX 400 Series GPUs, Blu-Ray 3D, CUDA 3.1 and OpenGL 4.0 support, new drivers are introducing enhanced configuration panel for Multi-GPU and PhysX configurations, with more intuitive interface.

In addition, it’s now posible to specify which GPU use for each CUDA (and PhysX) application via Manage 3D settings page.

You can download beta version of 257.15 Drivers here. PhysX System software 9.10.0222 included.
