_Dolphin don't work with SLI & Crossfire . Therefore , only 1 GPU is used
_Multi-player need more CPU power , the more player you add , the more slowdown you get
_Nvidia 600 series is known for having Idle issue with Dolphin (Idle clock speed when running Dolphin but some GPU don't have this issue ) . Set "Texture Cache" between "fast" and "safe" or set it to safe, you will fix that problem
Speed : Directx9 backend > Directx 11 > OpenGL (Depending on the game , some games run faster with Directx11)
SSAA of Directx9 backend is even more demanding than MSAA of Directx11
