Havok es a HavokFX nem ugyanaz, utobbi ami meghalt, az lett volna ugye ami a jatekokat a mennybe ropiti, mert a GPU-n keresztul is tudna a fizikat szamolni.

"The Saga of Havok FX
Of course, that's why Havok FX came along. Attempting to make use of shaders to implement a physics engine, Havok FX would have enabled developers to start looking at using more horsepower for effects physics without regard for dedicated hardware. While the contemporary GPUs might not have been able to match up to the physics processing power of the PhysX hardware, that really didn't matter because developers were never going to push PhysX to its limits if they wanted to sell games.
But, now that Intel has acquired Havok, it seems that Havok FX is no longer a priority. Or even a thing at all from what we can find. Obviously Intel would prefer all the physics processing stay on the CPU at this point. We can't really blame them; it's good business sense. But it is certainly not the most beneficial thing for the industry as a whole or for gamers in particular.
And now, with no promise of a physics SDK to support graphics cards, and slow adoption of PhysX hardware, NVIDIA saw itself with an opportunity."
