I am trying to run genymotion on a rMBP in HiDPI mode. Apparently my Virtualbox version already has <key>NSHighResolutionCapable</key> <true/>
set in Contents/Info.plist
Still genymotion does scale the vm up to 200%, which not only makes everything look pretty blurry, but also adds blurriness from downscaling.
I am using Virtualbox 4.3.2 and genymotion 1.3.1 on OSX 10.9.
