The IsEnabled function returns a value of true if Compute Unified Device Architecture (CUDA) acceleration is turned on and false otherwise.

Use the Enable function to turn CUDA acceleration on and off.

If your computer does not support CUDA, an error will be displayed. For more information about supported hardware, see Supported Hardware for CUDA Acceleration.
