This screensaver requires Direct3D acceleration. 1. 3D acceleration is not supported for Windows 64-bit guests (VMs). 2. 3D acceleration is experimental and incomplete, even for Windows 32-bit guests 3. Video memory only affects 2D graphics, so you can reduce it to 16 MB. VirtualBox automatically uses hosts's video memory, when 3D acceleration is active. -- -Alexey Eromenko "Technologov" ------------------------------------------------------------------------------ _______________________________________________ VBox-users-community mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/vbox-users-community
