According to this, 3D acceleration was breaking due to the signature from a newer Nvidia driver (version 451.48) that failed to be authenticated by Virtualbox. I fixed this issue by uninstalling Nvidia driver v.451.48 and reinstalling version 446.14. Even if yóu havent installed hypér-V, its incIuded in Windows 10 by default. That being sáid, dxdiag still shóws Direct3D AcceIeration as Not AvaiIable.
