If you noticed last week’s driver release, you might have been a bit puzzled about the fact that the word Crossfire has not been used, while the driver itself was exactly about bringing that to Vega. As it turns out, there have been a number of changes.

First off, much like Nvidia did, AMD will only support Multi-GPU rendering with two cards from now on. Meaning a three and four-way setup will not work any longer, this was confirmed by AMD bt PC World:

“We have delivered two-way mGPU support in games. Three- and four-way configurations will continue being supported in compute and professional applications.”

There is a second development, AMD is not calling Multi-GPU rendering Crossfire any longer. They just call it mGPU or Multi-GPU. In theory you can still yse more than 2 cards for gaming, but that would be a choice of the developer as they can use the a DX12 Explicit mode to accomplish that. Chances are pretty high that multi-GPU gaming is a dying breed with now both AMD and Nvidia limiting it by that much.
