Supersonic Rocket Sled – DX11 and PhysX technology demo from Nvidia is finally available for download (221 mb). Unfortunately, you won’t be able to run it until you have GTX 400 Series GPU.

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).

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).

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.
