Hey there, I noticed that on most powerful config for MBP 15 2017 scroll experience is quite bad. I cleared cache, history(when I typed some sentence I had beach ball spinning) and still is the same. I have second MBP by my side - but it's MBP without touchbar 2017 base config - and scrolling looks fine. Any ideas what's going on? EDIT: I tracked the FPS on 13 and 15. On 13 average for scrolling macrumors is 55, for 15 is 40-44. So it's not an illusion or something.
