This issue was posted by somebody else but not properly so I've taken it upon myself to re-post
My java version is not up to date, however this is because i've found the newer version of java (java 8) to be quite buggy at time so i've remained on the stable java 7
I am running windows 7 64 bit and my java version to be exact is Java 7 update 79
I have an NVIDIA GeForce GT 640 however that should be irrelevant. I have 8GB of RAM and a 2.9GHz Intel Pentium G645 processor.
This may be crucial or irrelevant I have no clue but i have a Logitech G430 Gaming Headset running Dolby surround sound.
Simply loading into the game causes this. It has severe audio issues. I have found that inside caves the audio is much less affected by this clipping and skipping. Aswell as when the game is minimized the clipping is not as bad either,
It seems to go hand and hand with whenever the game renders. Seeing as the game does not render nearly as much in caves or when the game is minimized however, my computer is more than powerful enough to render both audio and video of this game.
I experience no FPS problems or Freezing issues this is the only issue I have.
If you believe that a Java update is essential I shall do so.
