I've installed windows 8 on virtualbox 4.2.4 / Ubuntu 12.10. The virtual display graphics isn't fast enough, for example video on youtube (360/480p) is running with low frame rate.
Already installed guest additions and checked the 2D Video acceleration. with or without this feature, i get desktop graphics performance of 2.2 ... which is very low, compares to 3D business and gaming graphics performance that has a score of 4.0.
i would expect the 3D graphics score to be lower than the desktop/2D graphics score.
Is there any best practices that i can do in order to improve 2D performance?
