Postprocessing effects in a 3d game are graphical effects applied to each frame of video after it has been completed in the per-pixel rendering stages. They allow for special effects that require knowledge of more than one pixel at a time.

Postprocessing is an option in Guild Wars; their application may aid (or hinder) immersion, image quality, and framerate, but they have no effect on gameplay.

Guild Wars Usage[edit]

In Guild Wars, these postprocessing effects are known to be used for various effects:

Extreme Bloom
  • Desaturation: Draining the color from an image. Extreme applications result in black and white or sepia-type images; moderate usage just sucks the vitality from a scene. This is often seen in:
    • Death. When you are dead, the color drains from your view.
    • Mild desaturation can be used as part of the color control and finishing touches of a scene; this is harder to point out, but is one of the things that can cause an area to lose some of its feeling when postprocessing is disabled.

Heat Distortion
  • Distortion: An advanced transparency effect that warps the image behind transparent objects to create heat distortion, ripples of magical power, and similar effects. As it is applied in postprocess, the edges of solid objects that are in front of the distortion effect will often be slightly warped by it as well.

  • Warp, Blur, and Hue modification: These modifications are applied to the entire screen to mimic certain effects the player character is experiencing.
    • Used often for the Drunk effect with the amount of warping, etc. increasing with the drunk level.
    • Also used under the effect of Spiritual Possession.
