DirectX 12 will reportedly support multi-GPU configurations with both AMD and NVIDIA graphics cards

At this point, we’ve seen the magic that DirectX 12 can do even on preliminary software and drivers, and it has the potential to make games currently unplayable on existing PC’s run as smooth as butter. Today, we learn even more very exciting capabilities to come.
 
According to Toms Hardware and their source “with knowledge of the matter”, DirectX 12 is going to feature some pretty impressive multi-GPU support. Thanks to ‘Explicit Asynchronous Multi-GPU Capabilities’, DirectX 12 will allow games to utilize multiple GPUs as if they were a single unit. This would mean that instead of the Alternate Frame Rendering (AFR) technique that older APIs use where texture and geometry data in frame buffers have to be mirrored across GPU’s, DirectX 12 will use Split Frame Rendering (SFR) where a game would divide the texture and geometry data between the GPUs.
 
As a result, games can ensure that specific graphics workloads are distributed to the GPU that is better capable of processing it. This would also significantly reduce latency as SFR would result in a lower queue depth when it comes to rendering frames.
