Hi.. and ya.. you will need to install a Nvidia gpu. eg.. GTS 430, 450, 250 ect.. even a 9400GT or GT 220 should be enough.. gl.. see guide on pg 1

@ CovertCover & Rakivic

Would both of you help your selves and read comments of this thread or even read signature of almost everybody on this thread? What will you notice? ... oh well since I guess you guys are really lzy.... here goes:

You will need a 2nd graphic card - Nvidia - inside your computer 8XXX till 5XX etc - it must be an Nvidia PhysX capable card.

PhysX is only supported by Nvidia its not supported at all on ATI/AMD - when there is no Nvidia graphic card in your hardware(as main display GPU) PhysX is done entirely by your CPU which will decrease or take a huge performance hit on games that have PhysX enabled.... and by default even already having set an Nvidia card on your computer as your 2nd GPU *You cannot still use it as PhysX enabled card.

So what we do here on this thread is Provide a PhysX MOD that makes you have a 2nd Graphic card branded "Nvidia" as solely to be a fully dedicated enabled only for PhysX... and your CPU will not be stressed as before.

You cannot do this mod with ATI/AMD graphic card alone.... you will always need an extra Nvidia card in your hardware.

Hopefully this post you understood & as well it answered your tough difficult question. =P

Hi, I tried this hack once and had no luck but I want to try it again

I did read the post and some comments but I am a little bit confused about the command line part

I am about to put my GT 240 back in my system and install the new drivers, then I update the PhysX Sys Soft and run the patch. I know from my previous attempt I should create a fake display so that the PhysX gets tricked but where does the command line part some in?


EDIT * NICE, It worked, but GT 240 lacks some power, any suggestions? * EDIT

Does anybody know if a GTS 450 will make a big difference over a GT 240?

Depends on the game. In Mafia 2, yes.

In Unreal Tournament 3? Not really.

I have xfire 6850's and gtx260 but with three different nvidia drivers and mod 1.04 I get system instability.I have to go from 3.8 to 3.6 and add voltage to my cpu to get stable.

1.I also have a 8500gt that I use to watch movies on an old tv is this making it less stable?

2.Is it possible to run a old nvidia driver with no mod?

3.Or would it be more stable if I used the old driver with an old mod?

4.If I use an old driver do I have to use old physx software?

EDIT:

Ok the instability is gone I dont know what helped but this is what I did.
1.removed all drivers including ati and physx threw control panel and device manager then ran driver sweeper.
2.installed 11.1a from this site.restart
3.installed the oldest driver I could find 181.71_geforce_win7_64bit_international_beta and physx 9.10.0513 and mod 1.03 then mod 1.04
4.without uninstalling anything I installed 257.15_desktop_win7_winvista_64bit_english_beta
5.truthfully it was 4am so im not sure if I ran the 1.04 mod again but if I was to guess I would say no.
I also had a issue were msi afterburner would not control the fan of my second 6850 if I had a tv connected and activated(to my 8500gt).
Now im surprised to see my fan profile is working on all 4 GPU'S.
As I said I dont know what helped could just be moving to 11.1a but at this point im just happy its working and if this helps someone else even better.

I read the thread here, and a few others and i think i got it right.
1.)Uninstall my old drivers
2.)restart
3.)Re-install Nvidia drivers
4.)Install ATi drivers
5.)Patch physX
6.Restart

How do i test it? I ran fluidmark but i have no idea where it would say if physX is enabled, and i went into Nvid CP and there is no option to set physx to my GT240?

It will work if the 8600 has its own monitor.
