I have a GTS250 card (old I know), under WS14 my VM's are enabled for 3D acceleration and when VMs start there are no error messages. If I upgrade to WS15 the same VM now gets error messages that there is no 3D acceleration enabled in the host. If I uninstall WS15 and reinstall WS14 then that exact same VM starts up without any 3D acceleration error messages. Whats changed in WS15 that now results in my acceleration no longer working? If I look at the specs pages both say they need DX10.1 but obviously that can not be the case because WS14 works and WS15 doesn't. Any idea's?
