Batman Arkham Asylum: Rigid Bodies PhysX patch for GTX480 and 470 owners

with 4 comments

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.

AMD and Nvidia: controversy over physics

with one comment

Decent article called “AMD and NVIDIA butt heads over physics” emerges on Atomic MPC website yesterday.

Richard Huddy, AMD’s Worldwide Developer Relations Manager, Ashu Rege, Nvidia’s Senior Director of Content and Technology, and Nadeem Mohammad, Nvidia’s Director of Product Management and PhysX, are speaking out against physics engines support strategies of their rival companies. During discussion, Bullet physics SDK is opposed to PhysX SDK.

Apart from slight pro-AMD tone and some factial mistakes in engines descriptions, it’s interesting read. Conclusion we are complitely agreed with:

Whether or not Bullet takes off remains to be seen, but the next few years will certainly be an interesting challenge for both companies.

However, as we’ve already took a view at AMD and PhysX relationship history, future of that AMD-promoted GPU Bullet and it’s implementation in games (not Bullet SDK itself) isn’t looking so bright and clear for us.

Hybrid PhysX: 197.xx drivers and PhysX performance fix

with 46 comments

Recent PhysX drivers 9.10.0222 and 197.xx NV GPU drivers are mostly incompatible with 1.02 GenL Mod for Hybrid PhysX systems (witch hunt, another round) – using this drivers set will results in Metro 2033 crashes, abnormal FluidMark behaviour and performance problems in other PhysX games.

However, user Containforum, known for his Hybrid PhysX installation guide and Catalyst 10.2 extended display fix, has come out with a solution – he created a “patch”, that resolves  performance problems (at least for FluidMark) and allows you to use Hybrid PhysX without necessity to extend display.

Update: You can download containforum’s fix 1.02 here (25 mb). GenL mod must be applied firstly.

Update #2: comment from GenL

Result can’t be called a “patch” anyway. This package contains several unmodified (unpatched) files from PhysX SS v9.09.1112 and v9.10.0129. While this can’t be a proper solution for newer versions of PhysX SS, i’m surprised it worked for people

Update #3: Extended display fix only.

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

It’s recommended to use it with 196.34 drivers and latest PhysX System Software.

Please use this post or comment at youtube to report if this fix is working with other GPU PhysX games, or any problems you will encounter.

Nvidia PhysX Demo: Raging Rapids Ride

with 12 comments

Apart from Supersonic Rocket Sled demo all of you are probably familar already, for GF100 launch Nvidia has prepared another technical PhysX demo, called Raging Rapids Ride, with boat riding down a montain river – maybe not so impressive in graphics aspect, but with intensive and complex real-time fluid simulation.

It using PhysX SDK based objects with custom hybrid water simulation, utilizing both heightfield fluid solver and particle simulation.  Boat behaviour is a little choppy, escpecially when it collides with waterside surface, but water simulation looks very impressive.

Update: You can download Raging Rapids Ride demo here

Grid based shallow water flowing pass a terrain with high slope is automatically turned into particle waterfall, and than – back to heightfield water (thus, two different fluid solvers are used simultaneously).

Nvidia GTX 480: up to 2.5x Performance in PhysX

with 2 comments

Well, NDA for new GTX480/470 GPUs from Nvidia is lifting now all over the world, and we are ready to spoil some details about PhysX computing capabilities of new GPUs.

Not bad, huh ? GTX 480 promises 2.5x performance gain over GTX 285 in PhysX calculations. To reinforce this statement, some benchmarking results vere revealed.

First one – for Raging Rapid Ride techno-demo, featuring complex water simulation (you can read our overview here).

Mafia II: first PhysX Trailer

with 5 comments

Assumptions about GPU PhysX support in upcoming Mafia II title are now becoming a reality.

Update: second PhysX trailer

With launch of their new GTX480/GTX470 GPU products, Nvidia has revealed a trailer, showcasing hardware accelerated PhysX content in Mafia II.

Amount of physics effects is looking impressive – various types of particle debris and chunks, sparks and smoke, destructible objects, APEX based clothing simulation. Not to mention, that apart from those effects, overall in-game physics in Mafia II is based on PhysX SDK too.

Will Mafia II become killer app for GPU PhysX many are waiting for ? We’ll know at August 24th 2010.
