Graphics Cards

Hello, I want to ask if MGPU technology can run under DX11, and whether it supports DX11 games? That is to say, will playing DX11 games with MGPU have the same effect as DX11's crossfire?

Overview

AMD MGPU technology harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve performance in games and applications. On systems with AMD MGPU enabled the video output is delivered through the primary GPU and the workload is allocated to all supported GPUs in the setup.

Multi-GPU support and performance varies by applications and graphics APIs. For example, games/applications using DirectX® 9, 10, 11 and OpenGL must run in exclusive full-screen mode to take advantage of AMD MGPU. For DirectX® 12 and Vulkan® titles, multi-GPU operation is exclusively handled by the application and configured from the in-app/game menu for graphics/video.
