Nvidia disables PhysX when ATI card is present

So, strike all that. I rebooted as Nvidia suggested and now the ATI card works now.

Okay, now I am getting another problems.

CCC won't boot up any more, it says that my current active GPU is not supported by CCC.

I have Windows set to use my 4870 X2 as it's primary display adapter and to extend my display to the 8800. Both cards are connected to my Acer AL2416W, the 4870 X2 using DVI and the 8800 GTX using DVI to VGA.

Just tried FluidMark and it's using my 4870 X2 as the renderer and not my 8800 GTX. In the Nvidia control Panel PhysX says that it is enabled.

Short: Plug the monitor cable in 4870, not 8800. Start PC. Wait.

Long: I had the same problem and thought that it was the PCI-E slot number that determined which card should be the default one. However after I spent an hour swapping cards in their slots (4870 is way too long and some cables had to be repositioned for it to fit) the nVidia card still WAS the default one.

My new guess is that the system chooses the card with a VGA output (8800 or 9600 which I have) as the default card during PC startup (4870x2 has 2 DVI outputs and no VGA).

Nevertheless, plug the monitor in 4870x2, not 8800. After you start the PC, the screen will stay black until Windows starts working and finds your monitor which is then activated. Then you can change all settings and install nVidia drivers.

The only drawback is that the screen will always stay black after you start the PC until Windows starts.

Well, I got PhysX to work. I uninstalled whatever .222 drivers they were and installed .1112 and used the Hybrid PhysX Extended Display Fix as well as GenL's mod.

Now I'm trying to figure out which settings I need to change to get increase in PhysX calculations? Do I need more Core clock, shader, or memory or a combination of just two or three?

If you don't mind, following up a little discussion we started with GenL in this thread

Quote:
You know, i was actually impressed by some of effects Mirror's Edge featured.
..snip.. snip..
I'd say it's because there are no detailed HD+60fps videos of all these effects (or i failed to find one)
Well, I can't argue about differences in video/game impressions, as they are looking same for me (because they are same, in fact), as for detailed videos and other info - well, that's what I'm trying to acomplish by this.
I dunno, how to make it more detailed without making it boring, complex, creation time over-consuming, etc

As I said, leave PR crap, give people actual information - and all will be happy (at least, I hope this time will come someday). Some kind of "health" GPU PhysX environment. With less screams like "Oh no ! Nvidia cheated on me !", with less "hardware PhysX is super-duper cool, 150 games are supporting it ", with less "PhysX is crap. It's used only in Batman, and only for sh*tty paper"
