If I drop items or let dispens them they floating in the air and the graphics start to glitch.

The redstone dos not be powered even if i place an energysorce next to a redstone dust.

The sound is broken ( if I place or deconstruct a block) the sound has an delay

If i place an Block or deconstruct it the graphics updates also with an delay.

If I put a item in a Itemframe an turn it the turn is also with an delay.

 Observer Clokcs dos work but so slow. ( The powerupdate of the Redstone is ultra slow).

Erverything is slower and with a delay.
