filament layers come apart on inside of circle

Slow down. Think of a string of hot plastic like a rubber band. If you stretch around a bend real fast then it will pull away from the bend as it cools. If you slow down then it will cool more as it is placed which will allow it to stick better. Depending on your software if it allows do inside perimeters at 25 or so.

What temp are you printing at ? Do you hear thumping noises in the extruder ?

205 seems kinda low, but I an stil noob in this matters. Maybe the "veterans" should try to answer this.

have you done a proper temperature calibration for the material you are using? a tall, single wall cube with temp changes every 10mm or so to determine what works best for that particular roll of filament... too cold & it will show cracking or peel apart easily, too hot & it will show bubbles (and often break/crack easily)... 
I usually start out with 5 degree temp changes, then narrow it down further by doing again with 1-2 degree temp changes to find the ideal setting.

I have found that the ideal temp can vary from one roll to another even with the same type of plastic. doing a temp calibration is now a regular part of my calibration routine when changing rolls. I keep a record of what works best for each roll I have - feed steps/mm, extrusion multiplier, & temp calibration. (I have 6 rolls of PLA in various colors, and 4 rolls of ABS in various colors - each one has different settings)

and yeah, as carl said - speed matters, too.

Slow down the speed on your perimeters slightly
