Hi, I have the 15" 2017 MacBook Pro with Intel HD Graphics 630 as the low-power chip and the Radeon Pro 555 as the high-performing one. I don't understand why it doesn't switch to the Radeon Pro 555 if you do anything heavier than write a word document. Browsing the web, scrolling, watching Netflix/youtube.. whatever. Everything is choppy with the Intel HD chip. As soon as I turn the graphics switcher off in settings, everything runs so much smoother with the Radeon chip; scrolling apple's website, which is sort of a heavy graphic site, is a million times smoother.. Another problem I'm experiencing is something peculiar happening when watching Netflix. On the Intel chip, green stripes irregularly pop up over the screen, less than a second before disappearing. I just feel bad for people not knowing that you can turn the Intel chip off because buying a $3000 machine with a worthless online experience, as a result, is just offensive.
