I ordered on release day, and was in the 3-5 category and was one of the first group of people to receive our rMBPs. About two weeks ago I started using it in 1920x1200 resolution, and it actually is performing really well. Tons of people on here have been complaining about lag and issues etc, however I've had none of it. One question though, when the screen locks, and the screensaver is on, when I want to log back in, the window doesn't appear. I can type my password and login like normal, but there isn't a box or my picture etc. This started to happen around the time I got my Apple TV and installed GFXCard Status. Can either be related?
