This pack removes unnecessary block faces that are rendered when the player normally cannot see them during normal gameplay. This will improve your framerate depending on how many of the blocks are used at once or under the right conditions. This causes side effects when you look at the blocks in spectator mode though as the faces would no longer be visible. See images for more info.
This pack will give you (depending on the scenario):
A slight increase or a more stable framerate
A decrease in VRAM usage
