This is more of a general curiosity question than a howto question. Just as the title says, do games have to explicitly support SLI/Crossfire to take advantage of multiple graphics cards or are they linked in such a way that you don't need to write extra code?

If explicit support is required, is it common for games to have this support?

No, it's handled at driver level, so even the graphics API doesn't have to know anything about the current hardware state.

I do think the driver needs to explicitly have a profile for the game to use crossfire/sli. – Roy T. Sep 29 '11 at 19:55
Ah, thanks for explaining. – TheLQ Sep 29 '11 at 21:19
