Excessive CPU Usage

After the 1.10 update minecraft has been using up to 85% of my cpu at times causing severe stuttering. During the 1.9 update i ran all max setting with a 64 chunk render distance and had no stuttering issues, but am unsure of what cpu usage was because i had never monitored it. As of the 1.10 update if my render distance is above 16 chunks and i begin travelling by elytra, my cpu usage will quickly climb to the 80%+ range and will stay there until i stop moving. even at a 16 chunk render distance i will see up to 60%+ cpu usage and mild stutter, and at 32 or above will hit 85%+(all of my remaning cpu uasge). On flat world type i can run max setting 80 chunk render and will see no stutter and ~50% usage.
