Houston, we may have a virus...

So today I downloaded the 1.03 physx mod linked to your signature, GenL. And I kept wondering why I didn't see the exe file after I extracted the archive. Then I notice my little antivirus alert and this is what I saw. o.O



So I don't know if someone hacked into that link and uploaded a virus or what, but I definitely can't see or run this application because my antivirus blocks it as an "infostealer" thingy. Could you look into this or point me to a place where I can download the mod without the "hidden extra"? Thanks.

vjcsmoke, both questions (about Fermi and about possible virus) are answered in FAQ.

To be precise, Fermi as a PhysX GPU was tested with 197.41 driver with a success, and no, there are no malware/viruses there (already without "hidden extra"). Just make your AV ignore it.

btw, looking at your screenshot, i suggest you read a rest of the FAQ too...

Does anyone know if it's possible to force PhysX processing on the secondary card for applications that won't do it natively?

Afaik there is no such application. They all are using a global setting from nvidia Control Panel.

Or there is a possibility that some application refuses to use GPU-PhysX at all, in this case you should delete its PhysX dlls, like in Mirror's Edge case.

I was specifically speaking of programs like Badaboom and other Nvidia demos that will only do PhysX on the rendering card. There are a few games that do this as well. For whatever reason they are ignoring the control panel settings.

Badaboom is using PhysX? Let me guess, you were referring to nvidia demos like Particle Fluid Demo (which are using custom GL extensions only available on nvidia GPUs) and Just Cause 2 (which is using Havok)?

If you meant CUDA, then there is an answer in my post with FAQ...

A: You don't. Developers should do it. GPU-PhysX is working through CUDA, this means CUDA is not blocked by a driver.

Dude, don't be a jackass, you know what I mean. Either you can answer the question or not. If not just say so, don't be a dick about it.

There are programs that use CUDA and/or PhysX that DO NOT run in a hybrid system because they won't use the secondary card. My question was simple: is there a way around this?

I assume, from your repeated snarky responses, you don't know the answer.

Sorry, i didn't mean to be snarky.

First thing to note - this thread is about PhysX in the first place.
Second - Badaboom is NOT using PhysX, but only CUDA, right? Or does it really using PhysX for some actions?
I remember seeing someone using some old driver (190 or older) and got Badaboom working, but i think it may be just an issue of the Badaboom, not a driver. I really don't think that someone will magically get a full CUDA support for any application with that old driver only, you know.

And finally, can you please provide the full list of these applications (known to you) that are using CUDA and/or PhysX that do not run in a hybrid system? This way we all can review this list and try to find the answers you seek.
