Use this option to choose whether you want the virtual machine to use GDI or DirectDraw to display the contents of the virtual screen.
GDI is the standard Windows graphical interface. VMware chooses this option by default. DirectDraw is the newer, higher performance graphics interface provided by Windows NT and Windows 2000. Unfortunately, DirectDraw will not work on all machines because certain display drivers do not support it or have bugs that prevent VMware from using it. Depending on which guest is running and which kinds of graphical operations the guest is doing, DirectDraw may provide better graphics performance for the guest than GDI. In particular, Linux guests appear to perform much better with DirectDraw. If you choose DirectDraw and it does not work correctly, then you should use GDI instead.
