PhysX 2.83 + Cuda GPU ???

This thread doesn't provide a solution or an answer for this issue but maybe a possible reason why it doesn't work (for everyone).

Has anyone tried soft body physics instead of RBD?

Well, after I logged this as a "Support Request" I got the following message
from our ever-vigilant mutual friend Stephen Blair, sent on the 4th of May:

Quote:

It is possible there may be an issue with PhysX acceleration and Softimage on 64-bit systems, and that is what the developers are trying to reproduce right now.

As I have not yet heard anything since, I guess they're still trying to reproduce it...

Anyway "my money" still is on some kind of official statement, but I've already sort of given up hope on this feature...

Reminds me of the old (maybe v5) feature of being able to use an external Ageia PhysX card (before they were aquired by Nvidia) for awesome RBD effects. Oh wait, that feature never materialized....

Ah, those were the days, my friend... :-j

FYI - This morning I got a mail, informing me, Softimage is still working on the problem...

Well, its been a while since I last heard something from Softimage
on this ever so fascinating topic... i-)

Luckily I'm absolutely sure the solution to this mystery will some day be magically revealed... :-j

Well, as I still haven't heard nothing new concerning my Support Request, I guess it's safe to call "CUDA accelerated PhysX in Softimage" in true "Mythbusters" style:

Next time on "SI Busters": distributed rendering?

Softimage 2011 sp1 still work with PhysX CPU?

Looks like it, yes. But that's after just one quick test...
The "PhysX Visual Indicator" still states everything runs through the CPU
and the simulations do not run at increased speed to previous versions
(so probably no "CUDA acceleration" :))

Correct me if I am wrong. Quadro does not support Physx. That is only available for Enthusiast cards like gaming.
Quadro does support CUDA. That is 2 different features that we are talking here.
