A user mentioned that we may see less smoothness in the new 15" MBPt for basic tasks because it uses the HD Graphics 530 vs Iris Pro. My proxy for this measure would be the 2012 rMBP 15" with HD Graphics 4000. Can I ask if you see any stutter in: Graphics intensive pages on Safari/Chrome? Transitions to Mission Control, minimising windows? These are the actions which use on the iGPU i assume, and I'm trying to guess if the new iGPU in the 2016 15" MBPt is going to see some transition lags or scrolling lags too.
