I know most games as well as DX12 don't support SLI. An RTX 2080 will play any game at 1080p 120FPS without ray tracing. If you run 4 RTX 2080s using NVidia Mosaic on a 4K screen. Each GPU displays one quadrant. So you would have 4 1080p quadrants. Could you now game at 4K 120FPS even though the cards aren't running in SLI mode. They are each just displaying their own quadrant??? From what I understand this is different than how SLI works. No????
