Multi GPU is always supported, SLI and CF are hardware related so any game can use them.In SLI and CF, all the cards split the load and then put the parts back together so it looks like there is one massive card, basically.
Multi CPU, while also technically hardware based, requires the game to be Multi CPU ready for some reason.

Someone explain this better please.
Actually you’ll find that multi-threading and sli are both done via the software. One of the biggest complaints about the c++ language is that there is no multi-threading language support. You’ll also find that Windows XP also lacked multi-threading support for quite some time. All SLI compatible games have an option to turn SLI on or off. Many older games were patched to allow for multi-core cpus but most were not updated for multi-core gpus. SLI wasn’t really developed for gaming, it kind of got pushed that way more or less. Most games today still don’t fully support SLI for this reason despite how long SLI has been in existence.
