Title basically says it all, was wondering how easily I could set up a 460 as a dedicated PhysX card with my 7950 as the primary card. As in what drivers etc. I would need to use. Thanks :)
 
I would like to know this also but will a 285 cut it? And is it even worth it the amount of power it would use?

I dont see the point in most of the games now but maybe newer games will be good.

Did you buy the 460 to use as a primary card or just for Physx? I'm thinking about getting a 440 for Physx and a 460 768mb as a spare primary card, but not sure if it is worth 25% more for the 1Gb version...
 
There is instructions in both the links below, but this is what you need to do:

First off you need to install the nvidia generic and regardless of which hack you need(if your lazy, just use the Hybridize one) that's detailed further below, install the nvidia driver, but when it extracts close the nvidia installer, then browse to extraction folder and delete hdmi
driver, 3d driver etc so that you are just left with the gpu driver
and the physx file-as even if you untick the other stuff, it has
installed them regardless with me in the past.

Depending on what games you play-up to Batman AC, use the physx mod up to(including the specific physx used with the working driver on the
1-05ff mod)

If however, you want to play B2, then the newest hybridize mod is what
you use-but, I don't know if you get the FULL physx effect as some say
it misses some of the effects due to it being a blanket fix of sorts
while specific titles have tweaked physx for said specific title, if
that makes any sense.

You should download both anyway as iirc, there is batch files to make
the gpu the default physx renderer.

In the case of B2 you need to manually set the config file to use gpu
physx after you do the hack or it will default to cpu on AMD gpus.

I may not have explained it very well guys, but it is relatively simple really.

If you install the Hybridize mod, you need to manually delete any Physx files in the exe's directory as well, but you don't have to if you use the older PhysX hacks.



Don't be rude guys and if this helps, it's nice to be polite.:p

Cheaper to buy a gubbed one off the bay you crazy *******, I thought you were taking the **** in the rufurb thread.:D
 
I'm in a similar boat, fancy trying the hybrid physx thing (mainly because I haven't played with any new toys for a couple of months), but don't know which card to pick to give it a shot with.

I am thinking mainly for the Batman games and maybe Mirrors Edge at present. Currently using a 7970 at 5760x1080 and don't know whether to go for a 440 or a 460. The price difference isn't too much, but the power draw is - between bus powered only for the 440 or 2x6-pin for the 460. Also, would there be any advantage to a 1GB 460 over the 768MB if it's purely being used for PhysX?

Decisions, decisions! :)
 
I'm doing this in my next build, 660 with a 650 as a dedicated PhysX card.

OP: You need Hybrid PhysX mod if you're combining it with an AMD card.
 
Hi Guys,

I can confirm that having a 7970 and a GT630 for physx, that the hybridize mod works a treat, I play both Batman games, Metro 2033, Borderlands 2 and Physx works fine, as mentioned just delete the correct DLL's in the games directory.

To answer the cuda question yes this will also continue to work, I use Expression Encoder 4 and it's uses the 630 for encoding.

hope this helps a few of you .
 
Was really torn between the 440 (which should be enough) and the 460 (which will almost certainly be overkill) and came down on the side of the 460 because it'll look better through the case window. :) Shallow, moi?!

Now to wait and see how it plays when it's installed and set up.

I just bought both :) I'll probably use the 440 as a Physx card (as it is low power consumption and heat output) with the 460 as a spare card/could be used in a future mini build. I got the 460 1Gb btw.
 
Word of note guys, you must run hybridize once you've installed the Nvidia driver, if you upgrade the driver run it again, else you will blue screen. Speaking from experience.
 
Hmm... Would doing this steal too much bandwidth from my 7950 on a Z77 board (would then be at PCIe3 x8/8 speed) - or even if I had a second 7950 in xfire (then x8/4/4)?

3.0 is double 2.0 bandwidth.
Considering GPUs don't saturate PCI-E 2.0 16x speeds, running at 3.0 8x is fine, even running at 4x will be fine (something like 0.1% decrease in performance)

Linus from LinusTechTips showed real world FPS drops/gains from 4x/8x/16x lanes....nowt.
