I've been experiencing extremely slow graphics when using win7 on a mbp retina. I'd like to know if this is common and what your settings are. Alternatively, is win8 a better option regarding virtual OS performance in VBox.
I've tried both with 3D support and without and it is always so sluggish. I'm trying to use some CAD software and currently it seems impossible. I was running a much smoother win7 on a mbp 2010, which seems pretty ridiculous
