Nvidia has released a small PhysX patch for Batman: Arkham Asylum title.

Update [30.01.2012]: Newer version of RRB library is available, to ensure compatibility with 4xx/5xx series GPUs.

Patch for owners with GeForce 400 Series cards and up and Batman: Arkham Asylum game.

Requires: R290 Graphics driver or greater.

In order to experience Batman: Arkham Asylum to its fullest extent when running PhysX on
Geforce 400 Series cards and up, users will need to replace the existing RRB.DLL file with
a new one. By default, the RRB.DLL can be found in one of the following directoires
depending on the version of Batman Arkham Asylum:
“…\Square Enix\Batman Arkham Asylum\Binaries”
“…\Square Enix\Batman Arkham Asylum GOTY\Binaries”
“…\Steam\Steamapps\common\batman arkham asylum\Binaries“

Where the … is replaced by one of the following depending on the OS version and if it
is a Steam version of the game:
C:\Program Files\
C:\Program Files (x86)\

If it is not located in this directory, please do a search for the filename
on your system.

The CUDA DLL cudart32_41_0.dll must also be copied to the same Binaries directory where
the RRB.dll file is located.

RRB.DLL is responsible for GPU accelerated Rigid Bodies calculations – large-scale physics effect, mostly memorable from Scarecrow nightmares.

You can download PhysX Rigid Bodies patch from here (3 mb).

Thanks to Stefan for update.

You see ? Only two months passed and I was able to fix it

Small patch for Dark Void title emerges today – it’s purpose is to resolve issues with PhysX mini-driver, called “Game System Installer”, which was able to corrupt existing PhysX System Software installation (my personal experience), and cause other problems.

From nzone.com:

An earlier version of PhysX System Installer, called “Game System Installer”, was inadvertently provided and subsequently incorporated into the released version of Dark Void for PC. This version is not compatible with some accelerated PhysX configurations and features, most notably the ability to turn on the medium and high PhysX setting within the game.

Please use the new PhysX System Installer patch below which will automatically cleanup and update the PhysX subsystem to resolve this issue.

Please note, retail version of Dark Void requires main PhysX patch to be applied firstly.

Dark Void page at nzone.com was updated with two new downloads:

Dark Void – PhysX Patch (337 mb)

GeForce users who purchased a retail (boxed) copy of Dark Void. In order to play Dark Void with enhanced PhysX features, a patch must be installed.

Dark Void – PhysX Benchmark (901 mb)

Download the Dark Void PhysX Benchmark and get a taste of this dynamic third-person shooter experience!

Important Notice: Benchmark does not include APEX Turbulence based smoke and particles, so effects amount is equal to PhysX “Low” in-game setting.

If you are insterested in full scale GPU PhysX effects overview, refer to out PhysX comparison video.

Update: Some details on CPU utilization (Intel Core 2 Quad 9400 used)

PhysX set to “Low” – calculations on CPU. Min fps – 4 | Avg fps. – 10

PhysX set to “Low” – calculations on GPU. Min fps – 57 | Avg fps. – 66

Lower overall utilization with PhysX effects calculated on CPU can be explained -  probably, because of low fps other game threads (rendering, AI, sound) are waiting for physics to catch up every frame, and aren’t using CPU to full power. Still, additional PhysX effects are calculated on one core.

8monkey Labs devteam has prepared first patch for Darkest of Days title.

Some release notes highlights:

• Added support for more mouse buttons
• New PhysX system software (in fact it’s old 9.09.0814)
• Fixed crash in “Rebel Yell” mission
