Only the AEGIA PhysX physical card can turn on the AEGIA PhysX option in game. The game does not utilize GPU-based PhysX.

The version of PhysX supported by the City of Heroes engine utilizes the add-in AGEIA PhysX card, NOT Nvida Geforce GPU PhysX. |

Currently there are no known plans to implement Nvidia Geforce GPU PhysX for two reasons:
- First: Performance. The Performance gains from AGEIA PhysX were about the same as using a Dual Core processor over a Single core processor back when AGEIA PhysX was made available. With even Intel now offering affordable quad-core processors, there is very little incentive or reason for the development staff to spend time and money pushing a plug-in feature that was pretty much outperformed by just having another processing core.
- Second: OpenCL: http://www.khronos.org/registry/cl/ About the only major hardware / software vendor not backing OpenCL is Microsoft, mostly as they are pushing Direct Compute. The short version is that OpenCL enables software developers to expose parallel computing tasks to dedicated processors with a common code base: aka: OpenCL can do the exact same physics processing that PhysX did... on any processor with an OpenCL driver.
OpenCL is probably the route that Paragon Studio will take if / when bringing GPU accelerated physics back is feasible. OpenCL code will work across all existing AMD and Intel x86 processors, most DX10 / OpenGL 3.0 class graphics cards, and if Nvidia can be bothered, the original AGEIA Physx card as well.
Basically this means Paragon Studios would only have to write one hardware physics acceleration code-base, maintain only one hardware physics acceleration code-base, and have that code-base supported on Apple, Linux, and Windows, across AMD, Nvidia, and Intel graphics.
If Paragon Studios were to update the PhysX component, they'd only have hardware physics acceleration on one platform (Nvidia), and would have to maintain a separate code base, with a separate API, for hardware acceleration on AMD and Intel hardware, or just settle for software support.
Well i think that was the best answer i ever got in a forum thank you.
