nice follow up article! it was mentioned that; "Affinity Multi-GPU: faster multi-GPU performance - Affinity Multi-GPU delivers significantly increased stereo rendering performance when using two or more GPUs. By assigning one or more GPUs to each eye and intelligently partitioning workload, Affinity Multi-GPU can cut rendering time nearly in half while doubling bandwidth and computational resources. So the simple explanation is that when we use two-GPU mGPU in a VR rendered game, each card is responsible for the image in each eye. I am not sure how it works with more than two GPUs, and AMD does allude to that being a possibility in its quote above." are you guys looking into this? it was be interest to see what 4 cards would do. you know, for science, shits and giggles!
