Configuring a video card to be a dedicated PhysX processor is very easy to do. Double click the NVIDIA logo that sits beside the computer’s clock on Windows, and click on the “Configure Surround, PhysX” link present on the left panel. The window shown in Figure 1 will be displayed. There, under “PhysX settings,” “Processor,” select the video card that will be the dedicated PhysX processor. In our case, we had a GeForce GTX 670 as our main video card and a GeForce GTX 260 that we wanted to configure as a dedicated PhysX processor.

After selecting the video card, check the box “Dedicate to PhysX,” as shown in Figure 2. Click on the button “Apply” and the configuration will be done.

Now you have your dedicated PhysX video card correctly configured. The next step is to enable hardware-based PhysX acceleration inside your game, which is done through its configuration menu.
