NVIDIA Removes Restriction on ATI GPUs with NVIDIA GPUs Processing PhysX

i was hoping to sell my two HD4890s and get a single HD5870 (asus most likey) than get a 9600 or equivalent, but Nvidia say its a mistake.... great (there is a extra reason for the Nv card as well called linux ;))

Physx is still nothing to get excited about but this is a sure sign Nvidia are hurting due to ATI's current popularity due to their 5000 cards, and probably poor fermi sales.

I personally think they blocked it so people didn't go out and buy an ATI DX11 card, abit of a coincidence that its been unlocked around the same time as Nvidia DX11 mainstream GPU's release..
 
Does any1 have a link to the beta drivers to download.
cant find them @ all. need the drivers that let u use nvidia with ati not the new modded ones that dont.

It's only a 100mb download, surely worth a try yourself?

so far i have spotted about 5 diff size downloads. dont want to instal and uninstall to find the right 1. dont want to mess my windows instalation up.
just would like to know where i can get them. that work.
 
If it's any help the one I have which works is exactly 159,236,352 bytes and size on disk of 159,240,192 bytes

Downloaded this morning from the nvidia website.

No options to enable physx, ran vantage before and after, no difference.

Has anybody found a link to or have a working version of the driver they could upload/share?

thanks.

Latest Nvidia control panel no longer has a seperate physx tick box. It's now under 3d section under CUDA. Have you selected your Nvidia card under that?

Works for me.
 
ah i didnt know that,

i've downloaded the ones from guru3d now and they are definitely showing on that tab as my 9500GT is enabled, but its only made 300points difference in the vantage score.

wasn't expecting it to be powerful enough tbh, ah well, I'll trawl the bay for a low price 9800 :)
 
First thing that happened when i put my GTX8800 along side my Sapphire 5970, was my CPU O/C dropped from 3.93 to 3.2.

Also Games in general and benchmarks were down on the "GPU part". Not sure whether its a psu issue (OCZ 850 watt 80 amps total on 12v), but i've since taken it out.. Mirrors edge looks good mind, but my CPU (QX9650) went to 60+c during a 15 miunte or so session, were it's normally 52-56:confused:

Unless your PCI-e bus isn't locked adding an extra PCI-e device shouldn't really affect CPU OC stability - its probably either the PSU not upto it or the extra heat pushing it over the edge.

Only reason games would be down on the GPU part would be if having 2 GPUs on the board severely dropped the PCI-e bus speed to the port the rendering GPU was on - it would have to drop below x8 PCI-e 1.0 speeds really to have that big an impact.

Its not suprising CPU got warmer as you have an extra card in there chucking out heat and even tho the GPU is handling the main bulk of the PhysX calculations the extra effects also do need some extra time on the CPU also to sync it all together with the game engine/rendering.


EDIT: Oh just noticed you have an asus 780i motherboard :( when they were first out and being reviewed several reviewers noted they couldn't get as good CPU overclock with GPUs in SLI as with a single GPU on this board (some other nForce boards suffer from it too).

Is there any guarantee they won't be switching off phsyx support i.e. to guarantee they're not getting profit from people buying PhysX, then those who have gotten used to it don't want to have wasted their low-tier PhysX card and so buy Fermi?

not going to buy anything from nvida until they guarantee continued support.

if you keep the same drivers that support ati and nvidia card you wont have that problem.
 
Thinking of throwing my 8800gt in with 5870,can anyone advice whats the best/latest driver to use for the 8800? On 10.04 for the 5870 atm.
Mucho thanks ;)
*edit. been a long time since i read about hybrid physx but isnt there some kind of patch needed to be done to the driver also?
Mainly wanna try it out for mafia 2 :) Can then decide whether to keep the card in for when full game is out!
