DoF

Does anyone know how if there is a mod for RAVENFIELD that allows for a lightweight DoP effect on close objects (ex: gun models, walls when getting close, other such things) and if not, does anyone have a clue as to how I could make one without the use of reshade? Preferably something that wouldn’t cost 20 fps to use

(Again, looking for an option that doesn’t include the use of reshade)
