what is geforce cuda core usage in games?

is those cuda cores dormant when not used or a free resource for the game?

physx is one use of it i guess, or am i thinking of this totally wrong here?

From Wikipedia

In the computer game industry, GPUs are used not only for graphics rendering but also in game physics calculations (physical effects like debris, smoke, fire, fluids); examples include PhysX and Bullet. CUDA has also been used to accelerate non-graphical applications in computational biology, cryptography and other fields by an order of magnitude or more.:

Now my answer. :)

CUDA is really a way to use the GPU for applications other than graphics. so it does one or the other. If you have lots of parallel...

CUDA is really a way to use the GPU for applications other than graphics. so it does one or the other. If you have lots of parallel (more than 32 and preferable in the 1,000s) things that need computing with the same code and different data, then CUDA is incredibly fast.

It's relatively new and it will take a number of years before it gets more accepted. The development cycle for people to start thinking of a new game, then figure out how to use something like CUDA, for the libraries and compilers to become available and then for the game to be written may take quite a while.

We don't really know the schematics and how it calculates.

The only thing I can tell you is that CUDA is very good on gaming, it handles the CPU very well. My CPU usage is reduced 5 to 15% on CPU intensive games. That's why people it's really good on 3d rendering programs.

Physx on the other hand is an exclusive product and optimized for CUDA cores only.

That's ridiculous. Nvidia has made extensive material available for any person interested in knowing how it works and how to use it.

Even Wikipedia has the schematics.
