New technologies RT NVidia.

These are tools that may be in our scope Lumion in the future.

PhysX v3 and Apex.

PhysX is only GPU-accelerated on Nvidia cards, so for those of us with ATI cards the calculations use the CPU which unfortunately doesn't always ensure great performance.

The particle turbulence effect looks interesting - perhaps it would be useful as dust, insect swarms, or to guide a large flock of birds.

The cloth and Apex destructable objects have obviously been available for a while. If you're curious to see it in practice, you can download PhysX Lab for free from the Nvidia Developer Zone (you need to register and wait a little until they approve you). PhysX Lab allows you to create "pre-fractured" versions of your imported objects which can be imported (and destroyed :)) in UDK.

Ha! now who uses ATI  :D

You can use it with ATI as well, there's a certain mod that used to be and can still be done, and doesn't really take much to do, (and is legal).

The tech-demo is very much that, as with some others in the past from NVIDIA, high performance level tech that someday will arrive for more general usage.

The particle system displayed is very GPU intensive based, so any running via CPU is not practical as the CPU (even the most recent) cant handle the crunch calcs needed.

I've used both PhysX Lab and UKD to test it and it worked fine with my ATI card, but I must admit that I didn't test a gazillion Apex destructibles in one scene, and it obviously doesn't work if I try to set the GPU-acceleration flag for these object types in UDK.

Can you tell me more about the mod? Is it for PhysX Lab, or just for using PhysX in general in Windows-applications?

Hi Morten

This places is total for info on PhysX, I think the main site person is from Nv or at least seems to have all the inside that is useful for the community.

The link PhysXInfo.com.  Haven't checked up on it's use specifically with software tools like PhysX Lab.  Seems to be more mod stuff recently.
