Choice of PhysX Processor

Hello,
I recently bought GTA IV and I noticed some rather disappointing performance. After a multitude of custom settings in the NVIDIA control panel, etc., I noticed in the "Set PhysX Configuration" tab that I can choose my PhysX processor.
I have 3 possible choices: - Auto-select (recommended); - GeForce GT 555M; - Processor.
So I would like to know:
- What does this configuration involve, since the GeForce is my graphics card (I'm not very knowledgeable about this) and I have another Intel(R) HD Graphics Fam...? and I therefore don't see the link with the processor...
- Does the "processor" selection use a graphics card? I read on a forum that this disables PhysX, is that the case or does it use my second graphics card?
My configuration:
Asus N75SF series running Windows 7
GeForce GT 555M 2GB dedicated
Intel Core i7 2670QM 2.2GHz (and theoretically up to 3.10GHz in Turbo mode)
64-bit operating system.
Thank you for your help!

"What does this configuration consist of?"
It consists of selecting both the method AND the hardware with which the computer will have to calculate the physical effects requested by the game, as follows:
- auto-selection: "done according to what the program says by default"
- GeForce GT 555M: "do it with the graphics card processor"
- Processor: "do it software-wise - that is, by calculating everything brutally - with the main processor (the i7 2670QM in your case)"
"the GeForce is my graphics card"
I confirm.
"I have another one"
No, I don’t think so...
"Intel(R) HD Graphics Fam... [...] I don't see the connection with the processor"
It is not a graphics card, but a graphics coprocessor integrated into the main processor (which shares memory resources with it).
The graphics coprocessor is a set of integrated components, printed on the same surface as the main processor, and thus placed in the same case (hidden under the large heatsink in the PC). Its performance is sufficient for office work and a few less demanding games (2D games, older 3D games), but barely exceeds that of the smaller graphics cards (those under €60) and is pathetic compared to the performance of 'real' graphics cards, which feature dedicated memory, a processor specifically architected for 3D computing...
A graphics coprocessor (like the Intel HD Graphics 3xxx or 4xxx) is a bit like a glove box... handy, inexpensive, but small. The graphics card is the trunk. Imagine putting your groceries in the glove box, and you'll get an idea of the difference. ;)

Because manuals don't say everything...
But they don't say nothing either, huh!

However, in my case, the i7 processor (blah blah my version ^^) is indeed presented as a big deal when they sell it to you, so to go back to this story about choosing a processor for PhysX, does the choice "-processor" as indicated above make PhysX run on the i7, and if so, is it better than on the GeForce?
