Post-processing options are available for real-time final rendering. The use of these options can have an impact on the preformance affecting the framerete.
Screen Space Reflections
Generates reflections of 3D objects depending on the properties of the materials. They bring an extra realism by reflecting the objects between them but there may be situations in which these reflections are not captured. They are not recommended in the case of flat mirror reflections, but they work well as reflections at ground level or as fresnel reflections.
Sharpeness
This option enhances the clarity of the rendering by amplifying the contours.
