Nvidia GTX280/260 and 9800GTX/+ 177.39 Beta Driver with PhysX-Support

[fireice2]

im using two cards... but i dont think the other one is working as a physx card. any way to check if its working?

[s3rv3r]

With the driver 177.39 I had gain performance.

In the PhysX's driver properties it gives you the choice to determine which card you use as the PhysX's card.

[STaRGaZeR]

Look at UT3, it destroys 4850 now

Try some PhysX games with this enabled and tell me if your framerate has increased or decreased. PhysX cube demos and 3DMark PhysX tests are not allowed

Not necessarily, because GPU won't have to wait for CPU data to render

What are you talking about man?

can anyone test if you can use one of your GFX cards as dedicated physx card?

just figured i'd chime in since i missed this thread.

i have an ageia Card and an 8800 GTX so i will fire up Vantage and show you what the scores are like using an Ageia card.

i wish that Ea would allow nvidia physx support for supcom forged alliance. Nothing is more annoying than spending three hours building up a strike force armada of tech3 gunships just to see your fps drop dramatically (in the range of 10-15) when you give the assault order. (this is with a q6600 at 3.6, and a g92 8800gts 512 btw) It's obvious that the game is cpu limited.


EDIT can someone please test actual game performance? My beloved g92 is on the lamb (rma).

Thats the weird part... I can't choose which card... I've tested the 8800GT recently. Physx worked. Now I have both the 9800GTX and 8800GT, I cant choose to assign the 8800GT or the 9800GTX as the physx card.

GPU Acceleration Of PhysX In Games

GPU acceleration of PhysX is currently supported only in 3DMark Vantage and Unreal Tournament 3. Future games that will support GPU acceleration of PhysX include :

* Mstar
* Mirrors Edge
* Empire : Total War
* Backbreaker
* Pwnage

There are other games that use the PhysX API but they do not specifically support GPU acceleration of PhysX.

I thought any game supporting PhysX will take advantage

There are quite alot of PhysX games released, mostly because of UE3, but almost all of them is software based.

For all games with PhysX support no increase of performance should be observed.

Unless...

The game already supports hardware acceleration, the game is being patched to support hardware acceleration, or it is forced by the user.

The last option is clearly the best, if it was easy to do.

No, not at all. Most PhysX games are done using software acceleration, so a PhysX isn't needed, and the option for hardware acceleration is left out. Only games that would see a gain with a PhysX card, will see gains with GPU card. Without any changes or patches done to the game and its files.

At least, until it can be forced to do hardware acceleration, which may not be so hard to do.

[Punisher!]

I want physX on my 8800GTX! GRR!

[Seraphiel]

I want physX on my 8800GTX! GRR!

I am in the G80 group support for this as well. I think, it'll come sooner rather than later. Even though I have a PhysX card...

[cantankerous]

I am really wondering if running physx on the video card could warranty me removing my Ageia card from my system altogether or would it still be best to keep a dedicated card due to the video card being slowed down if it must be used for physx calculations as well.

[Luka_Aveiro]

Ok, so I installed UT3, patch 1.2, physx mod by ageia.

I only have 2GB vista x64 and unreal took me more than 1GB memory for itself

Gaming became unplayable, just as soon as memory runs out, but physx were working alright. Guess I'll have to get 4gb memory ASAP

That is a very good question, and one I am puzzled about as well.

If PhysX card + 8800 Ultra is slower than just using a single Ultra, then the answer is a clear one.

But with no support for G80, yet, AFAIK, then comparisons can't really be made. I am an Ultra user as well with a dedicated PhysX card. I am really puzzled if I'll loose SLI benefits, if I dedicated a single one for PhysX, and how it all would compare to Ultra SLI + PhysX, or using one as GPU and one as PhysX.

If there is a driver for G80 PhysX that worked now, for Vista Ultimate x64, then I would install the OS and do the benchmarks myself. Unfortunately, that doesn't appear to be possible

[RAW-Raptor22]

Anybody have a XP x64 modded inf. for 8800GT 512?

Thanks! And if you dont, maybe warboy can help?

I am not too concerned about keeping my 8800 Ultra in replacement of the Ageia card PLUS adding in another video card. I was thinking more along the lines of getting getting rid of my 8800 Ultra and Ageia Physx card and getting an overclocked GTX 280 in replacement of both to do the job of both. I am wondering if having a single GTX 280 doing both GFX and Physx work would be a bad idea and I should just stick with the GTX 280 as a replacement for my 8800 Ultra for merely GFX yet still keep the AGEIA card solely for physx. If the GTX 280 can do both with no real loss than I would love to free up the slot in my PC that the AGEIA card is using now as well as cut back on heat, noise and power. Something tells me I am expecting way too much however.

Maybe, I'll see what I can cook up in a bit, I'm playing Spore right now.

Sorry for OT but how are you playing spore?

The Spore Character Creator came out a few days ago.

As you say, UE3 games use PhysX but not hardware accelerated. Only UT3 has hardware support. And of course, if you use only one card you'll see perfomance decrease 100% sure. If a chip is doing two task at the same time it will be slower than if it's doing only one. You'll see that behaviour in your daily UT3 usage. The tests in the first post are like techdemos for physics, not real game situations.

People, don't be fooled by this. You'll only see benefit by using a second card and this second card only doing physic calculations.

Thanks bro, no hurries besides the want for physx and more ppd from F@H.

[BobyTT]

If I would need an Nvidia board to run PhysX, then this so pointless.

Not for the people with NV boards.

Oh ok, I thought you were playing the full game. I was like wtf how did I miss the launch date for this game lol.

[dinos22]

i tried PhysX drivers with my 8400GS LOL and it doesn't seem to work (grayed out) but i can run those physx demos
