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.

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.

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.

New PhysX System Software 9.10.0222, which comes with recently released Metro 2033 title, emerges on the web.

Recent Geforce 196.75 GPU drivers from Nvidia have brought us something interesting – they include new PhysX System Software 9.10.0129.

This release is smaller than previous 9.09.1112 drivers – only 27 mb vs 34 mb previously, and is dated 29 January 2010, according to PhysX drivers naming system.

Update: Simple look at drivers installation folder reveals that engine .dll’s for SDK 2.7.3, 2.7.4.. all to 2.8.3 were updated with new subversions. No major changes except this.

Update #2: PhysX System software 9.10.0129 is now available as separate download from Nvidia website.

Includes the latest PhysX runtime builds to support all released PhysX content including Dark Void and others.

Supports NVIDIA PhysX acceleration on all GeForce 8-series, 9-series, 100-series, 200-series, and 300-series GPUs with a minimum of 256MB dedicated graphics memory and 32 CUDA cores. Note: Some applications may have higher minimum requirements.

Supports NVIDIA PhysX acceleration on GeForce via CUDA 3.0 for SDK versions 2.7.1, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 2.8.0, 2.8.1 and 2.8.3 (requires graphics driver v196.21 or later).

Supports control of your GPU PhysX configuration from the NVIDIA display driver control panel. (requires graphics driver v196.21 or later).

Despite the fact that guide is Italian, english version of Windows was used, so it’s easy to follow the process just by watching video carefully.

Other guides you may refer to: Link#1 | Link#2 | Link#3 (Please note that most of them refer to old PhysX mod 1.01 – use 1.02 mod instead, download link above) | Link#4 | Link#5 (video guide) | Link#6 (specific details) | Link#7 | Link#8 (detailed) <- it’s recommended to start from newer links.

Catalyst 10.2 and extended display error fix.

This guide is detailed enough, takes new version of GenL mod into account, and is probably one of the best Hybrid PhysX related articles we’ve seen so far.

Update: Catalyst 10.2 and extended display error fix – in addition, you’ll be able to use dedicated NV GPU for PhysX without necessity to extend display.

Official Release Notes are also available:

• Includes the latest PhysX runtime builds to support all released PhysX content including Batman Arkham Asylum and others.
• This release also resolves issues with Arabic language installations and occasional simulation interruption on some machines and titles.
• New runtimes for the PhysX SDK 2.8.3.
• Supports NVIDIA PhysX acceleration on all GeForce 8-series, 9-series, 100-series and 200-series GPUs with a minimum of 256MB dedicated graphics memory and 32 CUDA cores. Note: Some applications may have higher minimum requirements.

In addition, according to our sources, PhysX System Software 9.09.1112 will be included into next release of public GeForce drivers.

Update: as expected, this System Software leaked too – download | Mirror #1 | Mirror #2

Update #2: official WHQL version is available

UPDATE: Hybrid PhysX mod 1.03 released – with timebomb fix and lastest drivers support.

- added support for new checks in 195.xx drivers
- added support for XP/2003 drivers
- both x86 and x64 are supported by a single mod now

Notes about the mod:
- Both x86 and x64 are supported by a single file now. If you are using x86 OS, you should just skip patching 64-bit binaries (press No when asked for a search).
- Don’t forget that you must be able to access nvidia control panel. For this connect nvidia GPU to the second input port of your monitor – physically or virtually (i don’t know if this is possible), or any other way you find. There are community-generated tutorials for this, i can’t tell anything because i own only 1 GPU.
- Lite version may come later, if needed. Additionally, i can fix errors if you find them and release it with an update.

Notes about XP/2003 support:
- Only 195.62 drivers are tested for XP/2003 case. I can’t say anything about earlier versions, i didn’t even try them.
- It should work for XP/2003 x64 editions too, would be great if anyone will confirm.
- It will work for 2000 only if original XP/2003 package supports it.

Update #2: 1.02 mod is working with new 196.21 drivers.

Update #4: 1.02 mod may not work properly with 196.75/197.xx drivers, users are also reporting incompatibility with 9.10.0222 PhysX System Software.

In addition, original post contains mod for PhysX drivers 9.09.30, that allows to use original Ageia PPU with ATI cards.

Please use commentaries to this post or thread at NGHQ forums to report errors, if they’ll occur. Reports with positive results are also appreciated.
