The Dedicated PhysX card FAQ - Read this before asking any questions!

Not open for further replies.
i remember my last pc, bought three nvidia 260, hoped i could get 2 of them in sli and one as dedicated physx... end of story i only used 1 card the 5 years i had the thing, nice project.......crysis 1 was on top back then, could never get that thing playable.
 
the hybrid physx is no longer working with latest drivers , but 2013 games and before are all playable .
in xcom-bureau after the middle of game there are plenty of aliens and physx and need a card .
that is two month i started a new build with 3 gtx570 and a gtx280 , to play mafia2 and batman origin [that does not play with hybrid physx] with a lot of fps . batman origin is not as good as the first and the part where batman is under drugs , but some things are great , that is bad that there is no story and too much fights with too strong enemies .
the souncard is an asus hdav that has hdmi in-out , the gtx280 does the video in , hard-drives are two pci-e revodrive ;']
that should be great ....more over because i use a 2x cpu 6 cores 2.8 Ghz and 2 x 24 Go of ram .
i found nearly all on ebay at very good price . most things are second hand but all cards work and cpus + vgas are all watercooled so i think it is sure they will live long .
here is how it looks , sorry photo is not great because of not enough lights

in Nvidia CP should I set PhysX to GPU or CPU? or leave to Auto what is the difference?

It's simply where PhysX computations are run, either on GPU or CPU.

Auto will let it pick the best path for that game. I'd just leave it there.

I know this thread is very old however I would like to ask something. I have a question for running a dedicated PPU with my HD 4870 x2. Do I just install the drivers normally, and will it run as if it is a nVidia card?

No. If i remember correctly ATi had their own physics engine at the time called Havok. Nvidia PhysX is not cross compatible meaning that calculations will still be done by your CPU if you dont have a second compatible Nvidia card installed to take on the processing duties.

Why would you need to? todays CPUs are pretty strong and have a lot more cores for processing duties than in 2010. It would only really make sense if you had a really weak CPU and a spare PCI-E slot for a second graphics card.

And even then - the number of new games that came out over the last few years that supported physX out of the box are so few and far between that its not even worth wasting the PCI-E slot.

At that point why is there even still an option in Nvidia's drivers at all to turn change from auto/cpu/ or a specific GPU?
From what I've gathered threw digging. No new game will ever support GPU physX ever again, only raytracing I don't think any game will ever both, Nore does one now.

Yup every idea nv starts they abandon it.
 
So I noticed something
This is a picture of Control

Noticed in the red box it's not used at all Gpu1 139mhz No load
However, I noticed that in Metro Exodus Enhanced edition the Mhz change to like the card has has load it goes up to 1,152mhz but the load is 0% is this a bug?
This maybe because I don't have the original install maybe. I don't know. Does anyone have both and extra Nvidia GPU do test ?
