Nvidia SLI and off screen rendering

I am working on application using exclusively off screen rendering and antialiasing. I am using OpenGL API. There is no any OpenGl window output.

To improve speed I am considering usage of SLI technology.

What SLI mode will be most beneficial for me?
Is SLI AA mode also affecting off screen buffers (FBO, PB)?
Clarification will be greatly appreciated.
Thank you


If non-SLI rendering supports AA in FBO and PB it will support it in SLI. There is a bug with alpha output in current drivers, don’t know if they affect off screen buffers aswell…
