Nvidia disables PhysX when ATI card is present with an Nvidia card for windows 7.

I still persome he would land up with a radeon anyway, as they are out wayy before Nvidias new onces lets put it this way he may not be able to hold out and wait for the Nvida cards, considering seeing the price of them O_O

I m not going to upgrade(this PC) untill next year unless it don't cut it anymore

I've been looking at the 9800GT's for a while now to go with my 4870x2 when Windows 7 hits and now I can't go that route.

Oh well roll on OpenCl and Havoc.......

It looks better anyways...... Roll on DX11.

OpenCL allows such acceleration to switch between the GPU and CPU seamlessly and as needed depending on which is more available

That's the bit i really like.
 
Yeah, I'm much more impressed with Havok than anything I've seen with PhysX. The woman's skirt in the video above is very impressive and shows how something so subtle can add hugely to the realism. I also like the idea of load balancing between the CPU and GPU. We really need physics to move gaming on, as we're still stuck with predefined animations where characters end up standing in the air when on a slope and spin on the spot when turning. And physics could also be used to stop clipping, which is still an issue that plagues games.
 
It's strange as we were seing some interesting physics affects in games a long time ago with CPU's much less capable then we have now, yet with CPU's in the 3GHz+ range and four cores the effects we are seing today arent much better.

If you think Havok is terrible then i can see why you would think that.

The CPU is capable of physics as we have seen over the years with Havok on the PC & consoles, it just cant do as much as when its run on the GPU.

With the new Havok the load can be balanced between the GPU & the CPU depending on the implementation.

I thought it was self explanatory already.

Well quad core CPU's are a norm now and as time goes by we shall see Intel and AMD releasing CPUs with much more many cores that what is available today. That would make running physics on the CPU much more logical.

Anyway tech demos are nice but from what we have already seen in games using PhysX, currently the physics available in those games offer nothing special. You only see moving banners and paper and smoke, which we have already seen in the past.

PhysX acceleration on the CPU is terrible, not physics acceleration itself. The hardware requirement is more to force people to buy a particular product than an actual limitation, as PhysX was quickly ported to run on nVidia cards when the company had previously gone out of their way to state how dedicated hardware was necessary and how GPU physics wouldn't be able to affect the game world - obviously a CPU isn't as good as a GPU for physics, as it isn't as highly parallel, but load balancing provides a better solution.

snip!

Even the unoptimised PhysX acceleration on the CPU path can get the job done even when they try to make out otherwise.

Just lol, i can't believe this threads still going strong tbh.

Who gives a **** about PhsyX, its utterly useless, worthless, it'll hardly be used, so why everyone is crying about Nv disabling it when an ATi card is present i don't know, as no one is going to miss it are they, i certainly don't give a **** about it.

Funny how things change though, as i remember everytime Pottsey used to post about it, it was getting slagged to death by the same people, its crap, it won't be used blah, blah, blah, and now those same people are up in arms because they are disabling that utterly uselss, worthless feature that won't be used when an ATi card is present, i'll say it again :-

JUST LOL

A very simplistic view of the thread.

Its true though, everyone was calling it a gimmick, load of crap, useless, a worthless feature, it won't be used, it'll die off etc... etc..., its all there in Pottseys old threads, yet somehow thats changed now, as now those people are up in arms getting irate because Nv are disabling it when an ATi card is present, so can someone let me know how Nv doing that, has made this feature now so wonderful, and how its going to change the face of gaming forever, just by them disabling it when an ATi card is present, as i just can't fathom out how them doing that can, but it must have, as we have a 7 page thread here now, of those people now crying about them disabling that worthless, useless, gimmicky feature that won't ever be used so die off :confused:

Not sure that is the issue here. I always thought it was a gimmick myself so I never went for it, however my upgrade path was an 8800GTX to a 4870 so I was hoping to use it seeing as I already had one lying around.

It is more the principle than anything, it is the way Nv goes about business that people are "up in arms about". Every company is out there to make a profit but some companies seem to give little, if any, thought to the consumer.

I know the issue, its about Nvidia disabling it when an ATi card is used, so the only way to get PhysX, is by solely having a Nvidia card, you can't have an ATi card in there as well now, so what im saying is, why is everyone suddenly giving a now, when they were all saying before its was a worthless gimmick blah, blah, blah, so who cares if they are disabling it when an ATi card is present, you were not bothered about it anyway :p

Now you all want to have Nvidia cards in your PC's alongside your ATi ones, when all they are just going to be doing is spinning their fans, generating extra heat, and sucking extra power, you just couldn't make it up :D :D

ATi's in the same boat as them (Nvidia) now, as even they aren't using PhsyX, because no ones interested in the bugger :p

The thing is can you remember the individuals who are in this thread that had been using or planed to use PhsyX with an ATI & NV card when they said PhsyX was not worth it because i cant.

There really needs to be a majority percentage for the thread to be so.

I guess you think predicables are not worth fighting over, that your choice.
