Seems like nvidia released 177.39 which has physx working along with new physx software

seems it supports GTX 200 9800GTX and apparently G92 gpu so 8800GTS 512 and 8800GT which is working for me so :D
more support is coming within the weeks =]

NVIDIA PhysX Treiber 8.06.12

Drivers
the vista x64 ones are corrupted =[

http://www.tcmagazine.com/comments.php?shownews=20496&catid=3

but i installed the new physx software 8.06.12 and it seems to be working with 177.35
when running the test it seems to pause but then takes off fast so hopefully when 177.39 are ready to download it will fix the pausing

tried adding the inf hardware & manufacturer strings for 8800 GTX from my 175.16 driver, to the inf from the 177.35 vista x64 one, but it reboots as a standard VGA adapter

hopefully the 177.39's can be modded to use w/ g80 cards.. ;/

Argh - the XP 32-bit ones are mislabeled, they are in fact Vista 32-bit. No XP 32 drivers in sight. Grrr...

Edit: spoke too soon. I did get it to install on my 8800GT, not by using a modded inf, but by editing the one from the package. I just replaced all device IDs of 0612 with 0611 (9800GTX -> 8800GT) and it installed fine.

Is there a press release I can read about this?

Will it increase performance in all games or do games have to write code in to make the Physx work?

Also, before I install the 177.39 drivers, will those work with GPU2 Folding or do I have to put an INF file in that too?

See my post above. Extract the driver files in a folder and open up the inf file in notepad (for the XP drivers it's nv4_disp.inf). Search for all instances of 0612
and replace them with 0611. Save the file, and install the driver. Works like a charm for 8800GT.

:( @ proprietary stuff like this. Ageia bombed on its own, too bad being bought by NV gives them a lot more pull but still a small base of actual programs. I'd like to see the Havok API continue to be used in more games, AMD/ATi are generally more open about such things.

You are aware that the SDK for PhysX is available for free, and anyone can write programs for it, right?

I know starcraft 2 is going to have some basic physics in it. Like when you blow up a flying unit, it'll crash in flames on the floor and impact.

Is that the same as this Physx thing?

It's still going to be proprietary hardware-wise, that's what I meant.

Well seemed like ATI could licence this tech as well to install in there cards. Question is, is there alot of hardware change inside the card itself to accept it, or is it all software wise where it just utilizes the shaders to perform.

@ Redrummy's Vantage score.

I just read http://www.dailytech.com/article.aspx?newsid=12147

PhysX on the 9800 GTX+ is supported with driver version 177.39. NVIDIA also claims that the PhysX capability of the 9800 GTX+ gives a noticeable performance boost on 3DMark Vantage CPU test 2 to the tune of a 7.5 times gain.I'm excited to see some games where PhysX will make a big difference.

CPU test two measures physics performance. This test features a heavy workload of next-gen game physics computations. CPU test two also feature and air race of sorts, but with a more complex configuration of gates. The aircraft in the test trail smoke and collide with various cloth and soft-body obstacles, each other, and the ground. The smoke spreads, and reacts to the planes as they pass through it.

Havok was already more open and ran on CPUs, it's an API without the proprietary-to-CUDA-hardware solution like PhysX. Of course hardware could be optimized for it but one of the major reasons it had more support in games is because it was a more open API that didn't absolutely depend upon specific hardware. I guess the only problem is that Havk is an Intel subsidiary now :p

That must be the understatement of the year. LOL!

The reason for CUDA being developed was that the hardware was already there. CUDA is just a new way to utilize the hardware - and it's really good at it. Remember the physics demo that Intel did on Nehalem - it ran at about 20fps. Then nVidia ran it on PhysX and got 600fps. :)

MadMan007

06-20-08, 01:41 PM

I'd still rather see hardware optimized for a more open API. The way NV is treating PhysX is the same way they treat SLI 'only on our chipsets.' Perhaps they'll license it but who knows. Havok had a much larger base anyway, PhysX was always held back by the need for special hardware, now with NV cards using it that is less of an issue but it's still an issue.

Here's the list of NV/Ageia PhysX games:
http://www.nzone.com/object/nzone_physxgames_home.html

Here's a list of Havok titles:
http://www.havok.com/content/blogcategory/29/73/

Ok so maybe I was wrong in the total number of games supported, of course quality titles are more important than lots of mediocre ones. NV just has a lot of pull in the game industry, for good or bad, and the possibility of more stunts like the Assassin's Creed DX10.1 un-patching doesn't sit well with me. Having two physics options, one being more proprietary, just hurts game development and gamers too.

Too little, too late. I've seen higher CPU scores in 3DMark Vantage with the new modded drivers and PhysX enabled but where was it when I didn't have a quad core and some of these games were maxing out my Barton 2800? Now nothing maxes out my quad except Prime95 and perhaps I could even use a driver so my CPU can help supplement the performance of my 8800GT in Crysis. It's fine for those who have a good GPU but crappy CPU and with the few games that utilize it. I just hope this feature doesn't introduce a whole new set of bugs and BSOD's if implemented in future drivers for the 8800's.

Good point. I have an Nforce4 motherboard and an Opteron 185. I was thinking about getting two 9800GTX's to replace my 2900XT. Unfortunately the cost I would have to pay with buggy drivers and questionable performance with my old CPU may not be worth it. I think I may have to stay with ATI this round and lose out on GPU Physics for a little while...

I'm running an 8800 GS which has a g92 core, but I can't seem to get Physx going.
I'm running 177.39 drivers and 8.06.12 Physx driver.

Is there some configuration step I am missing, or something i need to add to my nv_disp.inf beyond just what is needed to make it install on my device?

I'm afraid I'm gonna have to wait till they release the second-class citizen drivers for the budget and older cards next month before I can play with physx.

No, you will have to extract the driver (7 zip can do this) and modify a text file called nv_disp.inf to add support for your card.
There are just 2 lines you need to add.

At the bottom in Localizable Strings add NVIDIA_G92.DEV_0600.1 = "NVIDIA GeForce 8800 GTS 512"

And near the top under [NVIDIA.Mfg.NTamd64.6.0] %NVIDIA_G92.DEV_0600.1% = nv_G9x, PCI\VEN_10DE&DEV_0600

Only for G92? (Not that I particularly CARE about PhysX now that I finally have capture in Premiere Pro working right...)

06-25-08, 12:46 PM

do you have to install the physx driver separately? or can you get the physx functionality with just 177.xx?

do these need to be modded to work with the 9800gx2?

Shatrat

06-25-08, 01:00 PM

yes, you do need to install the latest physx driver as well, link in first post.
Not sure if it works with 9800 GX2 yet, try it out and let us know :D

You may have to modify the nv_disp.inf to get it to install.

No, it is not, CUDA is a development environment that allows you to offload tasks from the CPU to the GPU, PhysX is more a specific subset of this which is an application set specific to video games that are offloaded to the GPU.

I would imagine they use CUDA to do it though. Hope that helped,

Yes it did, but there are many versions of CUDA and the PhysX driver is only for a selected few, but CUDA is for every 8 series card and up.. So can we safly say that the PhysX portion is only for 3 video cards? 260,280 and the 9800

Shell

06-27-08, 03:08 PM

Oh yay, a new way to horribly skew 3DMARK results.

If it were Havock I'd give a damn, at lease a lot of games use Havock, only a few use PhysX , but nVidia will milk it to the best of their ability, like advertising CUDA as a hardware feature...

06-27-08, 03:14 PM

9800gx2 = 2xg92 cores

there is nothign special about the 9800gx2 card. it is just 2x 8800GT cards slapped together to work as 1 card.

so yes this will work with the 9800gx2.

also the 9800gx2 uses teh same driver as all the other cards, so should be fairly simple

ChinStrap

06-27-08, 06:10 PM

it's two 8800 gts cards slapped together :)

8800gt 112 unified shaders
8800gts 128 unified shaders
9800gx2 128x2 unified shaders + samsung ram that clocks :)
