Often when I want to play survival singleplayer in Minecraft, I can't. This is due to chunks taking ages to load whenever I move to a new area of my map, leading me to regularly hit the esc button to help load the chunks faster. After being tired of this regular behavior of chunk loading, I decided to open up task manager to see how my computer was performing. Now, RAM isn't an issue, but when ever I load new chunks, the CPU usages goes up to almost 90%. Once it even got up to 93%! Is there anything I can do to diagnose the problem?
I'm running windows 7, Minecraft 1.7.10, with a view distance of 7.
