Install Chrome Dev Channel, go to about:flags and find Render all pages in GPU, and enable Threaded rendering. If you want, disable VSync as well but that's not as big of a performance improvement. Restart chrome. All pages now render at 60FPS (turn on the FPS counter to check) and sometimes 70FPS once the VSync is disabled. The lowest I saw was around 30-40FPS, and this was usually caused by overlaid div issues or semi transparent div backgrounds (again I think this is a software issue that will be solved) needless to say my scrolling issues have COMPLETELY disappeared and I forget I'm using a Retina display. Just wait till the software matures for this computer, people are too quick to jump the gun. If I can run Diablo 3 on 2880x1800 at 20 fps, I'm sure it can render some text on a screen. Definitely a software issue that'll improve over time, not a hardware problem. People are too early to jump on the "lets blame hardware" bandwagon.
