Rendering Issues

[MiniMacro45]

E.g. The Balloon from Immersive Engineering doesn't render, and when i try to position my character in the spot where it should be, i get forcibly teleported out of the area. (when placed on air)

The same goes with the Giant Lilypad from Atmospheric. It just loads a single block of it (it's 3x1x3) and i also get forcibly teleported out of the area where the lilypad is.

[F3 + A] doesn't help.

The blocks get quickly replaced to the block they are supposed to be when you place another block on their place.

Entities are moving like in 3 fps. They are very slow.

When i teleport to an structure far from the spawnpoint, it lasts almost 3 minutes to finish loading.

Another example, when i use The Magic Doorknob in a wall, it doesn't load the lower part of the door and i have to "carve" the doorway by rightclicking it.

Sponges sometimes do not suck all the water. They leave it in and you need to clear it with a bucket.

Is it due to lag?
