new geforce physx?

[erouz]

hi.
any body know that 8800gtx can accelerate physx?
and if yes is better to use 2*8800gtx in sli or one graphic and second physx?
tks for any info.

[Chruschef]

no, it can't accelerate phsyx, it doesn't have the shaders for it.
the 9800 series can i believe, as well at the GTX260/280.

Says who? Yes it can, even a 8800GTS 320 can do it, all 8xxx series and above.

[Chruschef]

the 8800 series does not support Ageia PhysX technology; says the nvidia website. nVidia has released drivers based on the PhysX technology to improve their older physics, but only the newer cards support "PhysX" because it requires certain hardware. I'm actually not sure if the 9 series supports it, but the GTX series does

[NaMcO]

Hmmm well, ok. My 9800GX2 supports it for sure and a friend of mine also increased his CPU score in Vantage with his 8800GTS G92. It does work... and officially supported since 177.83.

Also, both cards are selectable in the PhysX control panel. Dig out newer info.

[Chruschef]

it's just "accelerated" physics calculations, because the ageia calculations were better, so nvidia based their technology on ageia's after nVidia acquired it; the hardware is only in the newer cards.

[dengyong]

I'm using it.

[Chruschef]

Proves my point, it doesn't use the real PhysX. ^^.. i think i'm to blame for doing a bad job on explaining my point... :/

[NaMcO]

As i stated above, update your info, you're mislead... "Real PhysX", what do you mean by "REAL"? You mean it's real only if it uses the AGEIA PhysX card? Think about that for a moment...

It's hardware accelerated and way faster than the old lame PhysX card by AGEIA was.

EDIT: When nVidia bought AGEIA, they hired the support team to port the support software so it uses CUDA instead of the normal calls to a PhysX card. It's not using the PhysX card anymore, but it's using the GeForce GPU instead. It's also hardware accelerated, it's not "better", it's not "worse", it's faster and another way to do physics without the AGEIA card.

What "hardware" would that be ?

[Chruschef]

the streamers built into the chip on the PCB.. the older cores don't have the shaders for it.

Link please.

[Kondik]

Ofc from series 8 up it can use the GeForce Physx , my cousin plays PhysX maps with my in UT3 on lan + Warmonger + GRAW 2 without problems and his card is 8800GT
And allso nvidia stated it that anything since 8500GT + can be used as PhysX accelerator, but ofc 8500 would die doing that because the lack of power

[Chruschef]

I could've sworn that it didn't, they didn't even own ageia when they made the 8500GT.

[Clairvoyant129]

Don't listen to him, he has no idea what he is talking about. I used to use 8800GTX SLI before I picked up GTX 280s, they can use PhysX.

[Kondik]

I could've sworn that it didn't, they didn't even own ageia when they made the 8500GT.

Listen up dear friend the suport is based on technology not when what was made, everything that has programable shaders can do physX , 8500GT does , 7x series doesn't so anything over 8 series + WILL work with physX more or less.

"Like graphics, physics processing is made up of millions of parallel computations. The NVIDIA® GeForce® 8800GT GPU, with its 112 processors, can process parallel applications up to two orders of magnitude faster than a dual or quad-core CPU. "

"See, you do not need a power-house of a graphics card to deal with the PhysX calculations. Say you have an older GeForce 9600 GT or 8600 GT lying around and you upgraded towards a GeForce GTX 260 (or whatever). Then can you use your 9600 GT (or even 8600 GT) as a Physx unit and the GTX 260 for graphics."

So you got that ? :clap:

[Fungus]

BS, I got it working on my 7600GS too, so it just needs shaders...

Show us please.

gforce is agea they are teh same, but in the menu for the driver agea = cpu/ppu, gforce=cuda


I could've sworn that it didn't, they didn't even own ageia when they made the 8500GT.

its bassed on CUDA not anything added in


BS, I got it working on my 7600GS too, so it just needs shaders...

that card has no shaders it has pixel pipelines, pixel shaders and vertex shaders. it dose not have a steam processor (aka shader), u could do the cpu based but not the gforce

[Anemone]

Yeah there are a lot of folks who plan to put an old 8xxx or 9xxx series to work doing physics after upgrading.

[Fungus]

Ok I stand corrected, I must have been hallucinating. Sorry! =]

ahh then again I downgraded drivers because new ones aren't stable on AGP...

I'll reinstall current and see if it works =]

[erouz]

hi.
so any body try what is faster use 8800gtx in sli or one for graphic and second for phisx?
i have small problem whit 3dmark vantage so i cant try.

just use SLI, and with vantage your results dont count if u used a card for physx it gets disqualified as a non default bench and wont show up (or shouldent) on the ORB

[erouz]

i think that sort it that question.
that is answer from xfx suport
"[JAMES 23/08/2008 11:18:51] Hi, thanks for your message, can you please ewxpand on youre question, do you mean can you use a physix card with the 8800GTX? if that is what you mean then you will be able to use a physix card with your 8800 when the driver becomes available - drivers only availble for 9800GTX - GTX260 and GTX280 at the moment. kind regards, james

so that cart have physx but not supported yet.

[Marvin_The_Martian]

Funny thread.. someone needs to do more research before posting though ;)

Fungus proof to me you're running physx on your 7 series card lmao :rofl:

:rolleyes:

People come on, get real ok :up:

My 9600gt is Physx capable, just as much as an gxt280, less the lower computational power it has, it still has the FUNCTIONALITY.

[dinos22]

the 8800 series does not support Ageia PhysX technology; says the nvidia website. nVidia has released drivers based on the PhysX technology to improve their older physics, but only the newer cards support "PhysX" because it requires certain hardware. I'm actually not sure if the 9 series supports it, but the GTX series does

yes it does :)

[Kondik]

But drivers are allready available that was the so called Boom it works with all 8+ series Cards without any problems ...
My 8800 GT worked with it my GTX 280 does and there were tests with 8600GT, so 8Series up [ Programable pixel shaders ] can use physx and cuda

[erouz]

i dont by so sure or maybe not all when i was test on my friend 8800gt i cant turn on. and when i try on my i can turn on but i can choice any of my two card.

[dinos22]

you need to use a modded .INF file with newer drivers and then install physx drivers

have a look at original thread when these drivers were first released......tons of ppl got it working

[Marvin_The_Martian]

Or ask someone from the fah team, the same lib and hw making the card capable of physc make it also capable of crunching against deseases so we kind of know how to get it working ;)

There are threads in the fah section as well. But modded inf is no longer needed unless you have a very rare card. Just use these drivers.

http://www.nvidia.co.uk/content/forcewithin/uk/download.asp

If those are the one's you treid, and they don't install on your card, then inf modding is still needed but I don't think it will come that far.

[erouz]

i try next one 177,89 but i try this one as well.
is more because im interesting the proportion of between sli and physx.
which one give more power in new games.

[Marvin_The_Martian]

Ehm then you should definetly read the forums more as that has been discussed. Even in UT3 maps, general consensis was that the gpu physicx atm are quite useless. You will have to wait for those new games to see where the 'golden' balance leis.
