        {
            NxaSceneDescription description = new NxaSceneDescription();
            description.SimulationType = NxaSimulationType.Software;
            description.Gravity = new Vector3(0, -9.81f, 0);

I don't believe there's anything in the samples that should require the SDK to 
be 
installed, but what will be required is the PhysX System Software (aka Drivers) 
from 
Ageia.com, can you confirm you have the most up-to-date verison of these? 
(7.11.13).

you are very right, i had an earlier version of the system software, but does 
this
mean there is no back ward compatibility with previous versions, I ask because
I was wondering how to sync your new releases with ageia's

Ageia's current drivers support any application built with version 2.7.3 of the 
SDK 
and any SDK older than that.

To run applications/wrappers built using the 2.7.3 SDK you need the very newest 
System Software, there's no way around this without using an older version of 
the 
SDK. For example, were the application built using the 2.6.0 SDK, the System 
Software from 12 months ago would probably be fine, but it would also have 
numerous 
bugs and performance issues that have since been fixed.

I suspect I will update to the newest SDK every time a new one is made 
available, 
meaning if you're using a version of the wrapper built against (presumably) the 
upcoming 2.7.4 SDK, you'll probably need to update the System Software again. 
I'll 
make clear somewhere on the website when an SDK upgrade has occured and if 
there is 
a corresponding System Software update.

Does this answer your question?
