I have recently installed Revit on my windows interface via Parallels on a best of the line Macbook Pro. For some reason the display is hazy and the lines and annotations are not very clear. I have attached the picture here as well. Please advise in case you have faced the same difficulty before.
After reading around for a while, I found this solution:
I removed graphic acceleration from Revit Options. Works fine. Remember to close your file and reopen after making the change.
Also make sure you've installed the latest service pack. I believe it smoothed out some of the problems between Revit and Windows 8, even though Windows 8 is still not officially supported.
