      Description

      Using the default JVM options, memory usage in F3 screen indicates a constant 80-90% memory usage when using render distances around 16 chunks or higher, leading to ~96% memory usage during chunk loads, resulting in freezes of about a half second. Removing the default VM options results in improved performance because there are no noticeable GC pauses during chunk loading. Just want to make it aware that the default Minecraft VM options are not a good fit for all computer setups and cause problems at higher render distances.
