r.DepthOfField.DepthBlur.ResolutionScale

This scale multiplier only affects the CircleDOF DepthBlur feature. It's a temporary hackIt lineary scale the DepthBlur by the resolution increase over 1920 (in width), does only affect resolution larger than thatActual math: float Factor = max(ViewWidth / 1920 - 1, 0); DepthBlurRadius *= 1 + Factor * (CVar - 1 1: No adjustments (default x: if the resolution is 1920 there is no change, if 2x larger than 1920 it scale the radius by x
