Use OpenGL, set the Internal Resolution to 4 and Antialiasing to 4x SSAA. Or you can set the per game ini's to run at 6x IR. Read how in this thread: https://forums.dolphin-emu.org/Thread-unofficial-howto-using-gameini-settings-per-game

You can just set the IR to 6x in the global OpenGL ini file without having to do it individually for each game. In your Documents folder, under Dolphin Emulator/config/ there's a file called gfx_opengl.ini Under [Settings] adding EFBScale = 9 should enable 6x IR in every game which doesn't have a different value set in its ini.

I play in 4k and have my IR set to 7x and SSAA x4 anyway this is what MH3 looks like with 4x ir, SSAAx4 http://i.imgur.com/CrbBrUJ.png and at 7x ir with SSAA x4 http://i.imgur.com/d4gjLNK.png

A step-by-step 'walkthrough' is included in the GPU Performance Guide:

7xIR doesn't look any better than 6x on a 1080p display, but uses more resources.
Use 6xIR instead.

On a 4K display, you could use 12xIR (requires a high-end GPU), but the improvement in image quality would be very small.

How can a higher resolution (7x) look worse than a lower resolution (6x)? Do you have proof?

Downsampling works best when the virtual resolution is an integer multiple of the display resolution.

I was wondering like why are you talking about a 1080p display then I realized I linked the wrong images. Well to run 12xIR you need the fastest gpu even I can't run games at full speed at 12xIR with AA. I dropped down to 25 fps at 12xIR while fighting in MH3 anyway if you are up for the performance hit of setting your EFB to 15 here is some screenshots.

That is true. However, 4K resolution is 3840x2160 (7,516,800 pixels). When looking at Dolphin resolutions, the base resolution is 640x528.
So 6x puts you at 3840x3168 (12,165120 pixels). Looking at the edges you get multiples of 1x1.46 (+0x+.46), and looking at pixels gives 1.6183908 times number of pixels.
At 7x puts you at 4480x3696 (16,558,080 pixels). Looking at the edges you get multiples of 1.16x1.71(+.16x-.29), and looking at pixels gives 2.20280971 times number of pixels.

Neither are a true integer multiple of a 4K screen, but going by these numbers, wouldn't 7x be better at scaling?
(my logic could be totally flawed though, but this was my thought process on scaling)

6x is still better than 7x, because at least the virtual width (3840 px.) is an integer multiple of the real display width (1920 px.).
For a 4K screen, you should use 12xIR (8K downsampled to 4K).

You should TURN OFF AA when using very high IRs such as 6x or 12x.
