Is the HD4000 underpowered for retina screen?

[falconeight]

I have a MBPr 13in with i7 2.9ghz with 512ssd(apple refurb). I was worried about lag but after nearly 3mo I have seen none.

I use the default resolution and do not scale the screen. I do not play games on my laptop.

I have had no lag with video playback or any web browing. Only issue I see is using parallels with the limited ram sharing(13in only has 8gb of ram so Win7 is only getting 1gb of ram on my setup). But having access to Win7 is a golden value.

The screen is amazing and I love my purchase. Buy with no worries.

YOU LIE! Open email, then close your left eye while opening a door facing east, then unplug you rMBP and open calendar, and you will see a lag. So don't tell me it doesn't lag cause its a POS.

What? Why would Apple do such a thing if everything runs smoothly on Retinas?

Everything ran smoothly on DP2 indeed. Not sure why Apple bumped VRAM for HD 4000 to 1024MB in DP3. There's hardly any improvement in... anything. It just takes more system RAM.

Thank God I have 16GB...

I was being ironic and I didn't even know it was a DP3 change. Thought it was Mavericks since DP1. Well, mine has 16GB as well so it's all good

Switched from a 13" MBP Mid 2012 to a 15" rMBP Early 2013 and came here. It's a years old thread, but yes, the HD4000 cant handle the retina screen. UI Lag is here and my non Retina ran much smoother. Minimizing windows, opening folders in Launchpad, all the day by day stuff feels laggy on the retina.

That Apple shot the second generation 2013 MBP with a new GPU in the same year out should be evidence enough. I'm dissapointed and thinking about getting a 2015 MBP (The last true MacBook).

Cheers

I got them both here up and running and can compare btw.

Even the HD630 seems to struggle with the scaled resolution on the 15” touchbar models (they are non-integer scaled by default unlike the retina generation)
