ATI+NVIDIA Physx??? yes

My PM too, i understand it's not going to happen under vista. But,.... if there's a story it'd be interesting.

Someone tells what under Vista I need to install XP driver for GeForce. How?

 

[silkstone]

Won't work under vista at all

"If multiple graphics adapters are present in a system, all of them must use the same WDDM driver. If there are two graphics adapters with WDDM drivers from two different manufacturers, then Windows will disable one of them. The VGA adapter will be enabled, and the second device will be disabled.

Notice that XPDM drivers still support heterogeneous multi-adapter as they did in Windows XP. A user who has such a configuration working fine in Windows XP will encounter a problem when upgrading to Windows Vista. An external monitor connected to one of the graphics adapters will have no video signal, because it is disabled. An error message will appear on system boot, as described later in this article.

The solution for this problem could be as follows:

A user could force the installation of a XPDM driver for each of these devices, and therefore get heterogeneous multi-adapter multi-monitor to work as in Windows XP.

-Or-

The user could change the graphics hardware configuration by choosing multiple graphics adapters that use the same WDDM driver. Graphics adapters from the same ASIC family generally have the same graphics driver. In late 2006, each of the major graphics vendors had a single WDDM driver for all supported WDDM graphics adapters. Please consult the graphics vendor's Web site for details on their driver support."

So, has anyone dried forcing installaton of xpdm drivers? i imagine it would require you to disable digital driver certification in vista64?

according to this guy's post on guru3d, there's no benefit (no physx etc.) to running the xp drivers under vista:

not working for me

I put 1 ati 4850 + 1 8800 gt on an intel p45 mobo. I have xp sp3 installed in my computer. I followed all fit's steps but physx still doesn't seem to be used! Do you have any advice for me? Is there anything else i should do?

here's one screenshot that shows it's not being used:

Read thru the thread - Fits put up a step by step guide somewhere on here

Read thru the thread - Fits put up a step by step guide somewhere on here

I already followed this guide but i had no luck:

1. install all drivers and get everything working.

2. have both monitors up and running.

3. right click desktop and go to display properties and select display settings(adjust resolution).

4. make sure both vid cards have a desktop enabled, ONLY ONE.

5. select the nvidia card as your default/main desktop/monitor and hit APPLY(not ok, leave the window open)

6. open physx control panel and go to the physx card tab. it should now say physx is enabled. leave this open.

7. switch the default/main display back to the ati card(s) and hit apply.

8. in the physx control panel, click on ENABLE a few times so that APPLY becomes available once again. click apply and repeat this step again.

9. run your benchmark of physx enable games.

10. enjoy.

NOTE: the monitor on the physx card does not need to be left on at this point.

Does anyone know what should I do?

reinstall the os. sometimes i get a botched install and it doesnt work right. a quick reinstall and your set.

Got windows 7, got the 8600GTS set as main card and 4870x2 as second card. Then try and open Nvidia Control panel and the control panel program doesn't respond, gives an error message.

**EDIT**

Ok I had to roll back the drive a bit, but I got the control panel to open. I can't find anything about enabling Physx anywhere in the advanced settings though.

 

[1Kurgan1]

Ok did a bit more testing, set the 8600GTS as main desktop. Then opening Physx controls where in the settings tab it has 3 options "No Acceleration", "GeForce Physx", and "AGEIA Physx". "GeForce Physx" is what is selected at that point and "AGEIA Physx" is greyed out. I hit appply, then I switch the 4870x2 to main desktop. Go back to the Physx panel and hit "GeForce Physx" then I hit apply, and I repeat that step a few times for safety. As long as I leave that panel open it shows it as that.

But if I close it then reopen that settings tab it is set on "No Acceleration". And of course running Vantage shows also that it is not working. Also the "Info" tab for Physx says, "No AGEIA Physx Processor Installed".

Any help would be fantastic.

This is also with the newest build 7000.

 

[1Kurgan1]

Where are you Fit? help me :O

 

[Fitseries3]

this only works in the build i specified unless you have the DEV tools that i have. i cannot release them to the public.

I was promised a puppy, where is it?

 

[adrianx]

my cat eat your promised puppy, also my cat will eat all the promised puppy


FITSERIES3

can you post (repost)

all versions of the driver

like eg.

nvidia.... ver. 3434
ati ver....
windows 7.... 32/64bit
build....
physx....ver. ...


also any one have a ideea how the physx work on geforce card???

is hardware dedicated or a software that run at gpu level

also how is "real scalability" from 8600GT to 9800GT or gt260(or any).

I'm in total fog with that

 

[Fitseries3]

nvidia.... 178.XX upgrade to 180.48
ati ver.... 8.10(anything newer sucks)
windows 7.... 32bit build 6815(as mentioned)
physx.... whatever comes in the 178.XX

you have to install 178.XX drivers for some reason. i never got it to work until i did that. you can update to whatever version you want after that.

So is there any particular reason why 6815 works and 7000 doesn't? Other than the fact you mentioned you need dev tools?

 

[Fitseries3]

multi display drivers works in all the alphas and betas but you cannot enable physx in the later version because of a driver issue. it should be fixed by RTM build.

this is only when running ati and nvidia.

Gotcha, appreciate the quick response. So there is still hope. Haha.

Hey Mike - Welcome to TPU. Glas to see you made around these parts

 

[careverse]

Noticed this from the new physx driver changelog: "Resolves PhysX SDK runtime issues with multi-GPU configurations in Hybrid environments."

Does that mean vista might still have some hope left?

 

[Fitseries3]

there will never be a fix for vista. MS has just about pulled the plug on vista.

 

[careverse]

Figures...
Off to testing Windows 7 ->

 

[Fitseries3]

its better anyway...
