Cemu

When using OpenGL, the face of characters and some walls look dark and sometimes merely black so nothing you could see.
As of Vulkan, the dark problem get a little bit better, you can see something which is extremely dark of OpenGL. But Vulkan brings a new blur problem like what I showed in attachments.
And in the beginning of this game, there's a scene for you to set the brightness. But whatever you scroll it, the display got no difference at all. So I think this could be a reference of whether the light or shader is working correct or not.

Closed because issue #351 has more examples and details.
