I'm using Dolphin 3.5-1878 version (it's pretty recent). In D3D11 and OpenGL, the EFB copies to RAM option becomes slower and slower as I increase the internal resolution. No AA is used. For example, in TLOZ:TP, Kakariko Village:
DX11, EFB to RAM, 4xIR -> 35fps
DX11, EFB to RAM, 2xIR -> 40fps
DX11, EFB to RAM, 1xIR -> 54fps
DX11, EFB to Texture, 4xIR -> 54fps
DX9, EFB to RAM, 4xIR -> 54fps
DX9, EFB to Texture, 4xIR -> 54fps
OpenGL does pretty much the same as DX11.
I usually play at 4xIR in D3D9 and that's not a problem even with EFB to RAM enabled in Twilight Princess and The Last Story. EFB to RAM in D3D9 makes only some difference in some situations when playing TLS.
Does this happen to you?
