How to fix "A D3D11-compatible GPU (Feature Level 11.0, Shader Model 5.0) is required to run the engine"

I’m a total noob but what do you mean by add r.graphicsadapter=x?

like, where do i find the index of the graphics adapter that the engine is using?

I’m having this same issue w/ trying to run Fortnite on a laptop i was given for my 8 year old son (Asus Rog G73JH).
