Physx 8.07.18

Thanks for the link.

The help document only mentions:

"The PhysX engine will use an AGEIA PhysX Processor or an 8, 9, or GTX 200 series GeForce GPU with at least 256MB of memory."

... nothing about only 8600 and up. I'm going to try it on my 8400GS when I get home tonight.
 
UT3 and the PhysX demos in the PhysX Properties panel work fine on the 8800GT. That's all I tested so far.

What doesn't seem to work is mixed cards of different generations. I'll test an 8800GTS 320MB + 8400GS tomorrow, or maybe an 8800GT + 8600GT in case the minimum 8600 comment in the first post is correct..
 
I've tested on my 8800GTS320.
With the 177.79 beta driver, I got GeForce PhysX. It boosted my 3DMark Vantage score by about 1100 points, and the CPU test 2 was over 10 times as fast as before (the rest was virtually equal), so apparently it works quite well.

This is the oldest 8-series card, the original G80, so I guess they do have full support for 8 and 9-series now.
 
Is the link still up ? I can't seem to download a valid zip file.
 
So this will work with my 9800GTX+ with no extra hardware installed? Will this impact frame rates? Or is it just grabbing unused resources to process PhysX calls?

Those worked even w/o 8 series support. They just use software in that case.

In games that have PhysX support (which is not many) you may see some performance boost. You have to remember by using this, your taking away from GPU cycles. A sigle 9800GTX+ is not powerfull enough to handle PhysX + graphic duties.
 
It will impact frame rates vs actually having a standalone PPU or second card to do GPU PhysX. You don't get anything for free. ;) But it does open up the modest library of hardware PhysX games which give you extra effects. OTOH, it can increase framerates where the CPU is the bottleneck like in the UT3 PhysX levels.

There's supposedly another 12+ hardware PhysX games coming out by the end of the year.
 
Kind of figured that, might be amusing for Vantage or some games. Oh well, I don't have a PhysX enabled game installed at this point, so i won't worry too much. Plus I cold always use an excuse to buy a new motherboard =-)

That depends on how heavy those PhysX + graphics duties are.
Aside from that, there are 'dead cycles' during graphics processing that can be used to run PhysX shaders at no impact from the framerate.
On an 9800GTX+ these 'dead cycles' should already be enough to process the amount that a high-end CPU can handle during a game.
So generally you can either free up your CPU for other tasks (and in some cases make the game less CPU-limited and get better framerates), or you can get more physics than your CPU would allow you, while still having good framerates. GPU physics scale better than CPU physics.
 
I've tested the drivers with a 8600GTS and a 9800GTX and both work, Word is that they don't work with the 8800GTX nor 9600GT yet

It's a shame they didn't bench the Ati card along with the PPU. That would be the most logical choice anyway since it's the only card that CAN'T do PhysX on it's own anyway. I mean when I upgraded from my 8800GT to my 4850, I did so knowing I could still do PhysX on my PPU.

The computerbase.de link above tested the 9600GT alone and as a secondary card running GPU PhysX.

GotNoRice: That combination won't work under Vista. I hope MS enables multiple 3D accelerators from different manufacturers in the future.
 
so how would throwing in an old pci slot 8500gt gpu work alongside my 7950gt apg gpu? the drivers should work out with nvidias stuff right?

Well, I won't guarantee that it will work (partially because you're mixing multiple generations and multiple types of slots), but if the drivers detect multiple nVidia cards, you can choose on which card to run the PhysX acceleration.

No not yet... Using an old GPU as a dedicated PPU is still unsuported.

http://www.hothardware.com/Articles/NVIDIA_GPU_PhysX_Pack_Preview/

My favorite part, next to how much faster PhysX games ran...

"We bet that at least a couple of you are wondering about multi-GPU support. We learned a couple of days ago that NVIDIA plans to support a couple different modes for PhysX and multiple GPUs, but it is important to note that both are in the early stages of development.

In SLI mode, both GPUs take on the physics and graphics workload equally.

In Multi-GPU mode, on the other hand, the primary GPU (like a GTX 280) is dedicated to 3D graphics while the secondary GPU (like a 9600 GT) performs only PhysX calculations. This mode will be supported on both SLI and non-SLI motherboards.

Stay tuned to HotHardware for more PhysX coverage as the technology develops".

NOTE to all intel chipset based mobo guy's:
In Multi-GPU mode, SLI and non-SLI motherboards will be supported...
Were in baby!

I assume he meant the 8500GT as a PPU.
Older GPUs will never be able to support PhysX simply because the hardware isn't advanced enough (it doesn't support Cuda, in a nutshell).
You will need at least an 8-series card for PhysX.

You can use an 8500GT as a PPU next to a high-end 8-series or higher GPU. I just don't know 100% sure if it would also work when the high-end GPU is a 7-series card.
 
No, you could have two 280's right now, and one can not be a dedicated PPU yet. It will be supported in the near future, but not today.

A have my old 8600 GT waiting to be a dedicated PPU as soon as possible.

My 280 will be my GPU.
 
I see it!! I see it!! Thanks... You are 100% correct. :)

I would like to get a report from a user who successfully got a second gpu working as a dedicated PPU.

I am still scared to plug my 8600 GT into my Maximus along side of my 280. Not sure if any damage could result?

Damage? From plugging a card into a correct slot? Worst case would be a driver issue, or if you didn't have enough power for both cards, etc. The 8600 isn't blocking the air intake on the 280 right?
 
Correct, I just havent ever plugged 2 Nvidia cards into my intel mobo yet...

So no worries to test it out then? :)

I have in my 975X board. No SLI of course, but both cards work.
 
well what i meant was

use my AGP SLOT 7950gt gpu as my 3d card

then buy an 8500gt and pop it in my pci slot, and use that as my physx card.....of course if that card supports it

i suspect that you won't get particularly playable performance running an 8500gt for physx in any pertinent games, but i guess it wouldn't hurt to try.
 
So would, say, an old 8800 ultra run physx better than a 8500gt...I mean as a dedicated physx second card..The question is...does physx demand enough processing power to justify keeping the old 8800 ultra in my case with all its size and heat and power consumption when a cute little 8500gt can be had for the cheepz?

exactly

if i can go with the lowest available 8 series pci card, would it be better than a regular physx card or should i go with a straight dedicated physx card
 
Well, I found this screen impressive...

Granted, it's a 280, but even an average GPU's should kill a CPU in performance.
Cores 240
GFLOPS 930
Fluids 15X
Soft Bodies 12X
Cloth 13X

http://www.hothardware.com/Articles/NVIDIA_GPU_PhysX_Pack_Preview/

GPU's in general, just kick major butt as PhysX processors...

I have high hopes for my 8600 GT's PhysX calculating abilities.
Low Power, no need to water cool it... Both +'s.

I think it being a dedicated PhysX processor, is it's last chance to be considered fast!
The price was right too, just laying in my desk. ;)

unfortunately, i haven't seen anyone run benchmarks with lower than a 9600gt as a physx processor. though driver heaven shows that a ppu can keep up fairly well with a 9600gt for physx processing - from the following link:

http://www.driverheaven.net/articles.php?articleid=122

seeing as how a 8800 ultra should be much faster than a 9600gt, and hardware physx seems to scale pretty well, i would say the 8800 ultra with proper driver support for physx would smoke the 8500gt. furthermore, an 8500gt is 3-4x as slow as a 9600gt for 3d performance, which is slightly better for physx than a standalone ppu based on the article, so one would think the 8500gt would have difficulty keeping up. then again, i don't have an 8500gt (or 8600gt or 8400gs) to test, so i could be completely wrong. i guess we won't know till someone tries it out, eh?
