So the code to do SLI isn't the same as the code to do Crossfire?
They each have their own API?
- Most likely an API to hook into their drivers to tell it that it supports Crossfire and how to split rendering/etc
Will DX12's multiadapter mode make SLI and Crossfire obsolete?[/QUOTE]
- Maybe, depending on if/when developers code for DX12 multi-adapter as it isn't automatic. It will also be a very long time before games will be DX12-only, thus any games that the devs want to support multi-gpu and are also coding in DX11 would have to code for SLI/Xfire.
