yah it's call of duty 4 but i dont go online, i use it for mvm and its worked the whole time up until updating it just now i got the mxao to show shading but still stays blurry. mxao is the only effect i have on:
That looks to me as if ReShade or something else forces a LoD bias. See, textures can have mipmaps, lower resolution versions of the original,with indices 0 1 2 3,where 0 is full resolution and each following index as half width half height of the index before.
The LoD bias is an offset applied on this value so with a a LoD bias of 1 and want to read miplevel 2, the game gives me miplevel 3 instead.
Not only textures on 3D models can have mipmaps, but also the full screen textures like the color buffer you essentially captured there. Now MXAO utilizes those mipmaps for depth and color buffer to speed up the sampling where quality doesn't matter much. I presume some weird LoD bias applied by something forces MXAO to use a mipmap instead of the full resolution backbuffer when combining AO. and the game image.
How to solve this, no idea, since it's technically not even a problem caused by the shader.
