So I finally got all the components to my setup and am saddened by the poor performance of the 13" MBP /w TB with the LG 5K display. The performance of the 13" is generally bad even when disconnected from the display. I can't even play League of Legends on the lowest settings without getting over 20fps. And there always seems to be some stupid process mds mds_store (spotlight related crap) that hogs my performance and makes everything just terrible. I also notice many issues when the laptop is connected to the display. Sometimes the big curser (when you move your mouse very quickly) gets stuck to the screen. Resizing windows is choppy. Just general use is terrible. How could apple ship something like this with such bad performance with a monitor they claim will work. Is there a way to test if my SSD or system is in good health? Perhaps I have a defective unit. I ordered the laptop from B&H and I don't know if I can return it now... What can I do??
