It is Wiki....

Oranges to bananas, try this for cpu physx:

Please elaborate...

Still, if we ignore what engines have PhysX in them and only look at what games have implemented, I can’t help but feel Havok comes out on top as most “actually used” physics implementation.

Every Unity game does actually use PhysX.

Please elaborate...

Because not all games that use PhysX use the hardware accelerated version of PhysX. The software version of PhysX is used far more often, and pretty equivalent in capabilities to the software based Havok.

 

[EarthDog]

Gotcha. Perhaps the list from NVIDIA is more accurate then.

Deprecated at this point, if it's open now, ok I guess.

PhsyX is always software. I think it uses CUDA on NVIDIA GPUs. Maybe VUDA could be a path to make it work well on AMD and Intel chips. If PhysX doesn't get hardware support across the board, GPU accelerated PhsyX is dead for good.

At least now we know why the RTX cards are so expensive, us customers were paying the costs of outing this nasty little black box! Or is this nGreedias way of subverting the growing backlash against them, by giving away a little toy... Much cheaper than dropping the prices of their new cards, I suppose.

I hope someone makes a wrapper that intercepts PhysX calls to the GPU, and sends them to the CPU instead. Hell, it would probably run much better on modern high core count CPUs anyway, as well as freeing up precious GPU resources.

 

[R-T-B]

Havok? Practically every AAA game uses it because Intel allowed even console platforms to use it. It's easier to encapsulate.

I'm curious what the actual usage numbers are though. I see a lot of titles utilizing PhysX as well. To say it was dead is simply not true.

This should be embraced at any rate, as now AMD cards can do PhysX if they chose to implement it. You no longer have only NVIDIA to blame for the propietary nature of it as they just did away with that. You'd think that'd be a good thing.

Deprecated at this point

Hardly. Even if you have an AMD GPU chances are some games were running this on CPU. No matter how many times you utter it, it simple wasn't dead.

If they believed open sourcing this was going to cost them money, they wouldn't have done it, period. There is no obligation to do anything like that unless it is profitable. By opensourcing it they are probably ensuring wider adoption and they believe the good PR will generate more profits than PhysX was making.

Strange that back in 2008 AMD publicly stated that they would be open to work with nGreedia on getting PhysX to work on AMD cards, but only if it was done in such a way as to not deliberately cause performance issues with AMD hardware... nGreedia declined by not answering...

We all know that compute has always been AMD's strong point, and I guess nGreedia may have ended up looking bad if they had have given AMD the keys to the little black box.

 

[Fluffmeister]

AMD are such victims, what a cruel world.

Now they can support PhysX thanks to their overwhelming love of open source it is only a matter of time before they add support to their drivers.

Let's all count the days before they add support.

I wouldn't if I was them, that cappy software was hacked to run on a GPU in the first place, and has been basically abandoned ever since. But you live up to your name, don't you? Your pro nGreedia (does it hurt you when I type that?) comments are full of... Fluff...

For the record, I'm pro Wallet myself. I couldn't care less about AMD or nGreedia, unless they are raping my wallet or causing harm to my hobby, and one of those two companies is.

I'm just interested to know how a company "rapes a wallet". Besides, for someone that doesn't care you spend a awful amount of time crying about it.

Sorry, I forgot that you can't see past your nose, you really should get that looked at.

I'll go dry my tears with tissues from the real world, it looks quite different to when you could last see clearly.

Hello, everyone!
Stay on topic.
Stop the bickering, name calling and insults. (You know who you are.)

Thank You, Have a Nice Day!

nGreedias

You’re not edgy or cool using “Ngreedia”. Try just Having a responsible, mature conversation instead of repeatedly using “nGreedia”.

I hope someone makes a wrapper that intercepts PhysX calls to the GPU, and sends them to the CPU instead.

In the Nvidia control panel we have always been able to designate PhysX working on either the CPU or the GPU. Also, as others have pointed out, many games only call for the software use of PhysX, implemented through the CPU.

I guess nGreedia may have ended up looking bad if they had have given AMD the keys to the little black box.

Well, you have the keys now. Have at it.

has been basically abandoned ever since.

No, it hasn't.

As recently as Fermi it was actually nvidia with this edge, which is ironic considering that's around the time AMD made said offer.

Gpu vs cpu. If you wan't to compare apples to apples it's gpu-physX to Havok FX, oh wait that was canned right after intel bought Havok(What a surprise).

So for gpu physics:
physX: https://en.wikipedia.org/wiki/List_of_games_with_hardware-accelerated_PhysX_support
Havok FX: 0(one nvidia demo on year 2005 or so and one amd demo somewhere 2009)
Bullet: Er something, can't remember what but more than Havok FX...

For cpu physics:
Havok: https://en.wikipedia.org/wiki/List_of_games_using_Havok
PhysX: http://physxinfo.com/index.php?p=gam&f=cpu

We'll see if AMD can accelerate PhysX now. I'm not certain the BSD license even lets them.

You, err, might want to read said BSD license, mate.

Might be possible then. The question then becomes whether or not AMD thinks it is worth the resources to invest in making it work as it should.

Exactly. So possible. Less restrictive than GPL even as it allows commercial use.

The irony is I bet they'll argur it's worthless. So much salt.

 

[medi01]

What else would you call the most uses physics engine?

A parallel universe.

It doesn't even have to be AMD at this point. Anyone that know how to do it should be able to start porting PhysX over to use the directcompute API making it work universally on any GPU.

 

[rtwjunkie]

So it makes me wonder if Nvidia will still bundle PhysX in with the driver installs?

999% totally not worth. just let it dies naturally...
