Some time ago someone requested some type of circular tilt shift shader and I decided to enhance my personal solution into something more advanced.
FakeDOF replaces the real depth information with a customizable texture. Use it if the depth buffer can't be read, doesn't work properly, or simply for artistic purpose.
Note that FakeDOF itself doesn't blur/apply bokeh, you have to use one of the DOF Shaders for that task.

Example shots with centered focus parameters + MatsoDOF(Doom3):



Installation:
Download FakeDOF.fxh and ReShade.fxh (latter is necessary since FakeDOF needs to replace the GetLinearizedDepth function) from my repository.

Usage:
To enable FakeDOF, set the preprocessor definition "RESHADE_USE_FAKE_DEPTH". After that, parameters should show up in the list of shaders.
Here is a demonstration configuration video (with displaydepth enabled).
For now, you can change the blur curve and focus radius via the three parameters a, b, c.

What ReShade settings are you using dude? Looks great.
