Next time you might want to try and actually read what you quote:
PhysX technology is [...] the physics platform of more than 300 video games,[2] such as Bulletstorm, Need for Speed: Shift or Castlevania: Lords of Shadow. Most of these games use the CPU to process the physics simulations.

Havok is on the way out. Bullet is getting big, as is PhysX.

Do you know 3ds Max? It's the industry's most important 3d animation package (those things that games are made with). In its latest version it removed Havok (reactor engine) and replaced it by a PhysX-based engine.
Maya (another one of those things that games are made with)? Uses PhysX as of its latest version, too.

You got it all wrong. Many games uses Physx as their lead physics api like havok,euphoria etc all these run on CPU and the complexity in calculations is very less. Games that use simple Physx are Age of Empires III,Gears Of War,Mass Effect(xbox360),Singularity etc. The GPU physx(like the papers in batman:AA) and Apex(like Dark Void,Mafia 2) still runs best on Cuda gpus. Nvidia's Physx system is extremely advanced compared to Havok. Recently Autodesk replaced there Havok dynamics system with Physx which can run on CPU and GPU. You can try it out for yourself if u add a high quality cloth with massive amount of polygons the CPU starts lagging while the GPU was running at 60fps on the viewport. Like people think Nvidia is not scamming. I still want people to understand what the Cryostatis water physics was all about it would be impossible on CPU.

If it isn't GPU based PhysX then who cares? Most people are talking about the GPU based PhysX, which is what they want gone, or are saying is in limited amount of games.

The CPU variant is no different then current Havok, and nothing special(well neither are).

Why was my post deleted? It had nothing but opinion and no bashing of any kind. Maybe the quote, but why not just remove the quote instead? Censorship is horrible on here sometimes.

It also offloads more work from the CPU - leaving it more room for maybe even another Card for SLI. Stop being "hurr-durr only 15 games vs. Havok's 200 games". Havok has been around for 10 years. PhysX was acquired from Ageia while acquiring Ageia itself back in 2008.

EDIT: Not to mention Apex:
http://developer.nvidia.com/apex
It's interesting though because if I played a game with PhysX on and no one told me what PhysX does, I probably wouldn't notice it in comparison to a game that does not run PhysX.

Whether something in a game occurs in real-time or is pre-rendered probably would make little difference unless I was directly informed that one or the other was occurring beforehand.

Even putting all that aside, why the heck wouldn't they? Xbox games sell like crazy. Getting Physx on some of those games will get developers more familiar and comfortable with it. It will make it a recognized name in mainstream gaming (not just the elitists of the already small computer gaming crowd). And lastly (and this might be the important one to you) since almost ALL big games for PC these days are either console ports or cross-platform, it will remove the BIGGEST barrier preventing developers from embracing physx. At the moment, developers do not bother using physx because only a TINY percentage (COMPUTER gamers WITH Nvidia cards WHICH ARE POWERFUL ENOUGH to do physx and render the game with a good fps at the same time or a DEDICATED physx card... seriously.. not many of u, especially when you include console gamers) of gamers will ever use it. Its development cost and time for no gain. With Physx cross-platform now, cross platform games (the majority of games) can use it and actually profit from it.

Besides, its not like they can change what gpu's are in the xbox at this point. Nvidia might as well allow it on there to at least try to cash in on the HUGE xbox gaming populous.
Havok already works on all consoles, what's the point of switching over to a less efficient physics engine like PhysX?

GPU accleration on a console assumes you have spare GPU cycles, and developers tend to push consoles to their limits just to get the current rendering where it is, I doubt they'll sacrifice framerate for a few physics effects.

Nobody forces you to turn the effects on, so why exactly do you care whether the OPTION to enable them is there? Or is it a matter of "I can't have the effects (due to incompatible GPU), so nobody should have them"?

I think the biggest issue with GPU physx is the fact that the effects can be just as easily done on an open API like Bullet or Havok that is not dependent on a specific card e.g. Nvidia Cards only. So everyone can enjoy the game no matter the card they happen to be using.

I think another issue is that since physx is obviously optimized for Nvidia GPUs. Even with the development of physx to be more "open", e.g with CPU in mind. Physx will still not perform as well as APIs like Bullet or Havok on CPU which were and are developed with CPU first in mind.

Edit: Basically I think it is the idea of openness and not being restricted to using an Nvidia product just to run a game effectively, or being restricted to less of a game (features being turned off) just for running something other than an Nvidia product.

haha I will keep buying ATI GPU's and still not care, woooo cuda... go overpriced hardware go!

but can the VRM's handle it? BTW xbox360 has ATI/AMD hardware in it, so they just proved that it fully could work on ATI/MD hardware.
