The GPU selection allows you to select the Graphics Processing Unit used by Fred's Fractal Viewer. Fred accesses the GPU via the OpenCL library, so the OpenCL drivers must be installed on your system. Which OpenCL drivers are installed on your system generally depends on which vendor made you video graphics hardware. Fred's Fractal Viewer only uses the GPU to perform AntiAliasing. Fred's Fractal Factory uses the GPU to calculate Mandelbrot Escape Count values. Fred works fine if no GPU is available, but it runs a bit slower.

If Fred cannot find a GPU via the OpenCL library, then the only selection available will be 'GPU NOT USED'. Fred's Fractal Viewer will default to using a GPU if it can find one.
