Howdy and thanks for reading! I have my textures doing these weird things like moving when I move a block. Also instead of getting a sky texture when I name the file and check the sky flag it turns invisble. Do I need a patch or something?

Here are my PC specs:
Windows 7 Home Premium 64 bit
2.8 GHZ Processor
4 GB ram(3.12 usable) <--- I have no clue why it says that
Nvidia GeForce GT 610 graphics card

boolean my.awesomeness = so true;
