Great news!
If this built against the old 8.2 code, or the current 9.0 trunk?

Greetings:
The MOSES Team has completed integrating the Nvidia’s PhysX 3.33
physics engine into OpenSim. The source-code and documentation will
soon be made available on our public GitHub repository.
Those who adopt the released code will have a new physics engine
option for their regions, in addition to ODE and BulletSim.
The new PhysX capability provides cross-platform, optimized code that
supports real-time, multi-threaded physics calculations. From repeated
stress-testing, PhysX has supported more than 83% additional physical
objects and nearly half frame time (44%) than Bullet*.
We have also included the ability to run physics in "distributed
mode". Distributed physics allows for the physics engine to be
executed on a completely separate server from the rest of the OpenSim
application. Under the right hardware and networking conditions,
distributed mode can increase the maximum number of users and objects
in a region.
Soon we will share our completed work with the rest of the community.
Once available, please feel free to interact with the new engine,
analyze the source-code, pull from our repository, and share advancements.
Best regards,
Sean Mondesire
MOSES Team
[*] Single-threaded PhysX averaged 3,300 physical objects when the
SimFPS first dropped below 9 frames per second (FPS) after 30
independent runs. Same-thread BulletSim supported 1,800 physical
objects at the same FPS. No frame rate correction factor was used
during testing. Although SimFPS remained 11.33 when BulletSim ran on a
separate thread, this physics mode supported 600 fewer physical
objects than BulletSim-on-the-same-thread before the simulator’s
performance began to noticeably degrade. It was concluded that
separate-threaded BulletSim was the least stable mode of the
Bullet/PhysX physics engines, produced the highest frame times for
equal loads, and is not recommended as a physics configuration for
regions with more than 1,000 physical Active Prims.
