So i've just installed win7 through Bootcamp for the first time on my retina mac, was so simple! Everything worked fine. The only issue i have is that I'm having to lower the screen resolution from 2880x1800 because although it is useable everything is a bit small. When i use 2880x1800 everything is really clear and lovely. But when you lower the resolution to 1920x1200 or 1680x1050 things just aren't as clear and are a bit... Blurry? Is there anything you can do to make this better? Might be a bit of a stupid question... Apologies!
In what way do you mean "blurry?" It's normal for an LCD to look somewhat blurry when running at a non-native resolution. Windows defaults to 150% scale on the rMBP which might be small for your liking. Try going to Control Panel / Display / Set Custom Text Size (DPI), and jacking it up to 200%, then use 2880x1800 resolution.
Wow thank you, i didn't realise you could set custom scaling. I was using 2880x1800 with 150% and it was just about useable. But i set it to 175% and its perfect now. Windows has never looked so good!
