Finally decided on getting a rMBP (8gb/256gb mid 2014), but came across some threads on here talking about scrolling lag, UI lag, and stutters. I was hoping to get some feedback from owners on how prevalent this is, and what situations cause this lag if it exists - is just running at a non-optimized resolution?
Also, is this on Yosemite only? Is Mavericks smooth?
