GTS 450 and GTX 570 GPU does not loads on physx apps

[$kRITIKa$]

I just ended building my dual GPU configuration consisting of EVGA GTX570 Gainward GLH GTS SSC and 450 on the Asus P5E3 Deluxe X38. GTX570 is installed in the first PCIe x16 and GTS450 in the second PCIe x16. A display linked to the GTX570. Having set up Windows 7 64-bit NVIDIA 266.77 drivers and PhysX drivers and GTS450 9.10.0514 configured as committed PhysX card in the Nvidia control panel. Everything seems to be functioning fine - nearly too simple - so it began wondering about how to verify that it works. Now confuses me pretty bad. I do not know how to determine if and when the card 450 is doing its job.

I try to install MSI Afterburner and enter setup and configured to display the GPU2 use the clock and the core. Run liquid mark again with this open and watch to see if there use is shown in the chart. As you can see from my image of Crysis 2 does not use PhysX in all there because I have to use my dedicated PhysX card. When I run my application fluidmark is only 50-60% and temperatures rise, and that's just a PhysX card as a dedicated GTS 250. Sorry, I'm at work and only have a screenshot with me or I'll show what I mean exactly. You can also use the GPU-Z GPU or Windows 7 Gadget observer for use.

As temperatures alone do not tell the whole story of the PhysX cards because most of the time are not tense enough to heat. To see if PhysX is running on the CPU or you can enable GPU PhysX visual indicator, click the NVIDIA Control Panel 3D Settings in the menu bar and select "Show PhysX visual indicator." 3DMark 11 does not use PhysX, so cannot use your dedicated card.

Metro 2033 the use of PhysX, and take advantage of GPU processing power if set to "Advanced PhysX" gameplay options. Yes, it is stated, but in reality PhysX calculations seems to be very casual in Metro 2033. Since I have not noticed any PPU load or increase the temperature of my GPU dedicated to have all the most advanced options PhysX enabled. You could try to test Mafia uses PhysX at higher level.

I read in another forum posted by a guy who did some extended testing on "Metro 2033" with different settings and different cards PhysX PPU. The result was that there was no significant difference in the test FPS. In its GeForce 9800 GTX as PPU had either average or maximum load of around 11%, which would explain why in my 450GTS no load and no significant temperature response. Maybe some specific areas of the game with several calc physx extra mixed up, but I have not gotten there yet.
