No I haven't tried it, because the "supported products' list doesn't mention Quadro FX cards, "just" Quadro NVS cards.
Concerning your problem, my guess would be, that the person in the NVidia forum meant to say that the Quadro NVS series has no PhysX support, while he claimed Quadro cards in general have no PhysX support. But that's just an uninformed guess...

edit: this page however claims the NVS series can use PhysX.
Confused? 8-}

Perhaps u are right,,,, it may give me physx with ESA tool.

Anything new on this problem ? I got the same "PhysX - CPU" message with my 8800 GTS.
I installed nvidia forceware 257.21 driver and updated physx system software to v9.10.0224.

In the softimage script window i get the message "INFO: PhysX Hardware Scene created"
when i create ICE Rigid Body's using the Simulate Rigid Body node). But there is definitely
NO physx hardware support (i can proof this using taskmanager showing the cpu load).

I can also be sure that my system is running well with other PhysX applications,
because when starting some nvidia physx tech-demos they are all running fine
using my 8800gts hardware. They also show the "PhysX - GPU" information
when i set them to "use physx hardware" ... when i switch the tech-demo
to "no hardware" then the info turns to "PhysX - CPU" and i got a good cpu
load in taskmanager.

So, in fact: Softimage 2011 (SP1) is not using PhysX hardware and thats $§%$& !
I also tried changing the softimage included physx .dll's to the ones that nvidia
delivered with physx system software, but this doesnt affect anything in xsi.

Question: Is there ANYBODY out there who can confirm that Softimage 2011
really is using physx hardware ? Maybe not only by showing "PhysX - GPU" rather
then proof it through the taskmanager or up/down-clocking his graphics card which
will result in more/less performance in physx applications. (i did this in the tech-demo).

Well the lack of response from Autodesk|Softimage on this topic is actually the most shocking to me,
as they still actively advertise the feature on their product page and the accompanying Softimage 2011 brochure

Merely logging the words “PhysX Hardware is Enabled” in the script editor
isn't really my idea of a new feature... 8-}

And ever since I started protesting the lack of this feature too much, my Support Request of this feature
seems to have been conveniently swept under the carpet also. :-?

So I am least glad, that I'm not alone in not getting this mystery feature to work... :ymparty:

But that's hardly a real consolation to anyone, now is it?

Hi!

As far as I can tell, there is no change in performance while enabling and disabling the PhysX engine via the NVIDIA control panel, restarting soft and loading the scene again. All the same framerate on certain scenes. What a pity!

cheers,

I've written an email to nvidia and told them the physx problem.
I also told them that i spend 1.000 EUR on a Quadro FX 4800 to
benefit of PhysX and CUDA in softimage 2011. Maybe nvidia can
tell us what the problem is about. And i asked for a PhysX Plugin
for "older" softimage versions, because the crap is not working
"build in" Softimage 2011. Maybe they will develop an external
plugin for softimage, because they already did for Max & Maya.

I read in the autodesk forum that we should "ignore the physx cpu"
message and only look for "PhysX hardware enabled" message in the
script editor. But this cant be seriuos and must be a joke, because
everybody can proof that it is only CPU PhysX by watching the win
taskmanager. U can also proof this by switching between cpu and
gpu physx in nvidia control panel - there is no difference at all.

Please let us now, what Nvidia answers... :ympray:

I guess they will simply say that the problem (if they even admit to one)
lies on Softimage's side.
But it might be interesting, what they actually say...

Still no comment from AD|Softimage... ^#(^

Maybe I should move this thread to a subforum I know even "they" visit? =))

Sorry, no update today ... but a question to you all:

Maybe this PhysX CPU Problem is operating system related ?
I used Softimage 2011 (SP1) on a WinXP SP2 32Bit System.

I'm going to install WinXP SP2 x64 @ weekend for testing.
And then i will try Softimage 2011 (SP1) x86 and x64.
But i wont install Win7 ... never ever. So this test has
to be done by someone else please.

It's just a suggestion, because i will do everything to find
out why PhysX GPU (hardware) is not working in SI2011.
I dont believe that this "bug" is os related, but i have to
find out by myself.

I use Vista Business x64 (and you guessed it already: it doesn't work!)

Tested SI2011 and SI2011SP1 both

Hi

This issue is logged for futher investigation.
At this time, I don't have any more news or any possible workarounds.

Thanks for finally saying something in public about this topic :-bd

This still leaves some questions unanswered, obviously,
but it's good to know the problem can be officially confirmed
and it's an official topic of investigation still...

edit: and yes, I removed the other topic... ^#(^
