Crusher takes the opposite approach to most shader packs: instead of adding detail, it strips the picture down. It can limit how many colors appear on screen and shrink the resolution of the image, and each of these functions can be switched on or off on its own, so you can combine them the way you like.
The color reduction caps every channel at a chosen number of values plus black. With the color amount set to 2, for example, a channel is restricted to 0, 127 or 255. You can pick whether colors are reduced in RGB or HSV mode, and an optional 4×4 Bayer matrix dithering pass makes the limited palette look much smoother, at the cost of more flickering. The dithering follows both the color count and the pixel size.
The pixel effect enlarges pixels, and each large pixel takes the color of its top left pixel instead of blending the colors underneath. Larger pixel sizes may cause flickering on distant objects. The anti-flicker option reduces this by averaging the colors inside each large pixel, although it may lower performance.
For something truly chaotic, the corruption mode makes the game look as though the universe itself is being switched off. It began as a failed attempt at the anti-flicker feature and was later kept as a separate option. It produces a lot of flashing lights, so photosensitive players should not use it.
