Anyone notice the image quality (IQ) difference between using DirectX 11 backend and OpenGL when adjusting XFB:Real/Virtual/Disabled? I have found that adjusting XFB to real and virtual has various interesting effects in both backends as you guys shall see.
Notes
- All video backend settings are attached to this post;
- Where settings vary from those shown in the attached images - I have noted;
- DirectX 11 and DirectX 9 has the same IQ behaviour;
- Resident Evil 4 is used as an example but it applies to all games;
- You may notice that in DirectX 11 screenshots there is a weird green border. This is an Issue;
- XFB: disabled produces the same results as XFB: Virtual;
- The video backend behaviour shown below occurs in 3.5 stable x64;
- Screen shots are taken running 3.5 - 1801 x64 full screen;
- I have not manipulated the OpenGL images - the screen shot function in Dolphin gives me a varying screen shot area compared to using Direcxt X 11 backend and taking a screen shot!!!
Direct X 11 vs OpenGL (native resolution / XFB: Real)

Notice that the OpenGL backend looks nicer. Take note of the 'Leon' underneath the health bar, Leon's aliased arms and the text 'Talk' between both backends.

Both backends now produces the same IQ as [color=#ff0000](B)[/color].
Direct X 11 vs OpenGL (4x Internal Resolution / XFB: Real)

[color=#ff0000](F) [/color]OpenGL
Here's where it gets interesting. Direct X 11 backend produces the same IQ as [color=#ff0000](B) and [/color][color=#ff0000]©[color=#000000].
OpenGL produces a worst looking image and the same IQ as [/color][/color][color=#ff0000](A).[color=#000000] A reverse of what we saw in the first test.[/color]

[color=#ff0000](H)[/color] OpenGL
Nothing surprising here. 4 x Internal Resolution makes things looks sharp.

Confusing? Errrrm.... Yeah.
