playing GRAW 2 with no physx card, but with effects!

Well actually you do. Havok FX requires a dedicated card. To get the most out of it you need hardware. Havok FX costs a lot more for developers.

It runs on the graphics card though? I meant it doesn't 'need' a seperate card. You don't have to use another GPU dedicated to physics.

Does Nvidia have a setup like ATi do?

I believe you can use an older 1900 series card for physics with 2900's? Not sure though.

They way that ATI and Nvidia are envisioning HavokFX on the cards is to have one (preferably two for SLI/Crossfire) card for graphics, one card for physics. All there demo's were run this way.

so ill assume these triple crossfire/sli set ups are going to require an even more ludicrous power supply now.

Back on topic, I just tried this on my GRAW2 only got a hit of aruond 5fps that's pretty awesome. I think Ageia will really shine with UT3, or at least I hope they do as I was considering purchasing one for that.

what level of physics did you set it to? 1 or 2?

But its now going to be easier with the unified stream processors, so they can allocate certain amount to do physics.

graphics card struggle to do graphics alone, can only wonder what will happen to performance if they are made to do physics as well

martin9887 · 4 Aug 2007 at 12:50

Well, Im all for a dedicated card to do it but the support is terrible for Ageia PhysX.

When will we start to see these setups with CrossFire/SLi + Physics cards? For Havok etc.

when games NEED them, but not before

i agree, go to http://www.ageia.com/ and then at the top click "drivers & support" you will really see how bad it is

I dont think they will take off still, Quad core CPU's will be doing physics calculations, and then we'll be seeing 8Core CPU's from Intel, no need for Physx cards, look at that Alan wake, that will take advantage of Quad Core cpu's and use one whole core for Physics, no need for these cards, and to top it off, even the GPU's can do physix calculations and could even have 2 cards in crossfire and one doing physix, but nothing uses that yet.

i was impressed with the nuke video in crysis, if that can be done in software then i don;t see there being a need for hardware.

Exactly, and with the help of Quad Core CPU's, then 8 Core CPU's, who needs a Physx card?

Yeah I know

.

Alan Wake is looking very promising for Quad Core CPU's, It can dedicate a core to physics and wind effects etc, Good sign of things to come.

As you've mentioned with Quad and eventually 8-16 core CPU's they are falling short.

I wonder how Alan Wake will run on a Dual Core CPU? I suspect if there is a High/Medium/Low settings for Physix in game then for Dual Cores there may be a need to set it to Medium, maybe even an Ultra setting for future 8Core CPU's too.

I can't imagine it being bad on a Dual Core, Obviously with a Quad it'll be better.

Well actually you do. Havok FX requires a dedicated card. To get the most out of it you need hardware. Havok FX costs a lot more for developers.

“I think both Nvidia and ATI favoured Havok and they even said a Physics Chip could be put on a normal Graphics card or even a Soundcard in future, I dont think Ageia's Physics has much future IMO.“
People have been saying that for years. Havok FX has been out longer then the Ageia PPU. Guess what no games support it. Physics on the graphics card are with us now but developers don’t seem to care about it.

I don’t see how its going kill Ageia almost 2 years later and well its still useless.

You live in a dream world mate, your Physics card has very little support and if ATI and Nvidia both ignore it and go with Havoks method then so will games devs it will be the end of it, it was a waste of money at release and some would say it still is.

Pottsey · 4 Aug 2007 at 14:05

“It runs on the graphics card though? I meant it doesn't 'need' a seperate card. You don't have to use another GPU dedicated to physics.”
It does need a separate card. You need a 2nd or 3rd card doing physics only and nothing else. If you have 1 GPU you don’t get physics at least thats how I understand it. Ati want you to use 3 GPU’s.

“You live in a dream world mate, your Physics card has very little support and if ATI and Nvidia both ignore it and go with Havoks method then so will games devs it will be the end of it, it was a waste of money at release and some would say it still is.”
It’s not me who live’s in a dream world its people like you who are dreaming. Look at the facts. ATI and Nvidia have gone with Havok FX. It’s been out over a year and has zero game support. Major developers have even announced dropping Havok for Ageia.

ATI and Nvidia are losing when it comes to physic support. You talk about my physics card having little support well its got x1000+ more support then Havok FX and you call me living in a dream world. How can something doing 1000times worse be the end of Ageia?

“Alan wake, that will take advantage of Quad Core cpu's and use one whole core for Physics, no need for these cards, and to top it off,”
Alan wake is a good example of how quad cores are to weak for physics. It’s got no advanced physics only average physics. If that’s the best a quad core can do we need something better. GPU’s or PPU’s are tons better at physics then a CPU core.

“i agree, go to http://www.ageia.com/ and then at the top click "drivers & support" you will really see how bad it is ”
Err what’s wrong with that? What’s bad about it? They have drivers for all versions of windows and for both 64-bit and 32-bit for both XP and Vista, no major driver bugs left. I admit Ageia PR team and game list website is rubbish but support wise they are good. How does that link show they have bad support?

your correct, that link shows they have NO driver support

please keep the arguements over ppu's out of my thread please. i made this thread so i can tell people how to get physx effects in graw2 without needing a card, not to repeat this pointless arguement again and again

Pottsey · 4 Aug 2007 at 14:15

Sure thing ergonomics. Over at http://futuremark.yougamers.com/forum/showthread.php?t=56858 one guy says the tweak doesn’t work. I don’t know enough about it to work out what he has done wrong.

so does cpu physics look exactly the same as ppu physics in GRAW when the hack is enabled? or is there still some difference in the physics that the dedicated card shows?
