Cross fire and Unity?

Unity Engine
1

Using Unity 2019 latest version, is there anyway I can code my game to use crossfire? So it uses two amd graphics cards rather than one?

Don’t SLI and Crossfire just present themselves as a single GPU to applications? E.g. the details of crossfire are a graphics driver concern. By the time Unity is dealing with DirectX or whatever graphics API it’s using, the fact that there are two GPUs is completely unknown to the application.

At least that’s my understanding. In other words - I don’t think you have to do anything special from the perspective of creating a game.

I mean I just want to know how to code it so it supports it in my game.

As stated, they appear as a single GPU. There is nothing you need to do to explicitly support it. Though there are things you should avoid in order to not hurt performance.

Unfortunately the link to the AMD document in the above support article is broken. I’d try to find the current version, and follow anything it suggests.
