Definition

Visual Basic Public ReadOnly Property SupportsCopyToVideoMemory As Boolean
C# public bool SupportsCopyToVideoMemory { get; }
C++ public:
property bool SupportsCopyToVideoMemory {
        bool get();
}
JScript public function get SupportsCopyToVideoMemory() : boolean

Property Value

System.Boolean
Value that is true if the device can accelerate a memory copy from system memory to local video memory, or false if it cannot.

This property is read-only. 

Remarks

This capability guarantees that Device.UpdateSurface and Device.UpdateTexture calls are hardware-accelerated. If this capability is absent, the calls succeed, but are slower.
