1) Nobody was talking about client/server until you came storming in with your bizarre context-free blanket assertion.
2) In client/server, the server can validate positions sent by the client in order to prevent speed/teleport hacks, while still allowing the client to be immediately responsive under normal circumstances.
This is why I chose Physx for my physics engine. Knowing that it will be ported to hardware was a good sign to jump on board imho.
How will you handle the case of the end-user not having an nvidia card installed?
Insomniac is making an mmo, so yeah, they were discussion a client->server architecture even if it wasn't obvious, so yes, (using subcontext, and past knowledge) my comment was legitimate.
as far as the validation, that would be why i said:

For all of your 3D/2D resource needs:
If I plan to use to physX sdk for a 3D game, is it necessary to have a graphics card with certain capabilities?
My current system is uses a few years old Nvidia FX graphics card.
I'm planning to get a mac which runs an ATI radeon card. Will the physX sdk work on it as well?
I just need to show some reasonably realistic physical effects, not like those displayed in AAA titles.
For using Physx i think you just need to have the Physx runtime installed on the target PC, that's it. It doesn't require a Physx card or a special GFX card, those things can just improve the physics effects and speed.
