I’m writing applications on Microsoft Visual Studio 2005 using the OpenGL .
My computer has two graphic cards with SLI configuration (nVidia 9800 GT). Using different benchmark programs I checked that SLI is working properly.
How can I utilize the SLI configuration in my code? Do I have to include or link any additional libraries to my project? Do I have to use OpenGL extensions?
SLI is completely transparent to your application. The driver presents the two cards as one device to the OS, and does the ‘magic’ for you.
If you want to program the cards individually, you have to disable SLI and address them as two cards, e.g., using Equalizer (http://www.equalizergraphics.com).
