Fixed excessive pixelation on monitors with various resolutions.

There is a subtle pixelation filter in the game, along with a few other visual effects, and they are all intentional for story purposes. However, it turns out I forgot to add the settings that keep the pixelation strength consistent across different screen resolutions.As a result, if you were playing at a resolution higher or lower than the default, the pixelation could appear much stronger than intended.Rest assured, this has now been fixed.Just remember to turn off fullscreen.
