Random worlds will only half load with extremely grainy graphics. Various worlds are very choppy and freezing occurs often. MAIN issue is when i am chopping trees, mining anything, i have to hit things 1-6 times before i have them

Since the latest update I have been having the following issues:

1. Random worlds created will only half load with extremely grainy gameplay.

2. Any world I play in is very choppy and freezing occurs often.

3. Biggest issue is whether i am chopping trees, mining any type of block and even retrieving the bonus chests, i have to chop/hit things 1-6 times before i am able to obtain it. Also with this occurs in unison disappearance of wood, blocks, etc at random times while retrieving.
