This command will enable an emulation of the texture resource management system employed in earlier DirectX versions (such as 9.0c). While less efficient than the system currently in use by DBPro9Ex, some third party plugins are dependent on this type of management and will either crash or fail to create valid images when using the 9Ex runtime. See the description below for further details.

ENABLE VIRTUAL TEXTURE MANAGEMENT

This command does not return a value.

Certain third party plugins, such as DarkVIDEO, may depend on images to be created and handled in a way that is no longer supported by D3D9Ex.
In order to make these plugins work as intended you can call this command before creating any images that will be used by such a plugin. This will try to emulate the expected resource management functionality expected by said plugins, hopefully making them work as intended.
After creating any necessary textures / having the plugin create them, you will want to call DISABLE VIRTUAL TEXTURE MANAGEMENT to turn this behaviour off again - this will avoid redundant image copies being created and copied back and forth behind the scene by the DBPro runtime when it isn't necessary; ie. it will result in higher program efficiency and less memory wasting.
