Ray tracing doesn't render like your typical OGL/DirectX application. The initial view will always be somewhat grainy with photorealistic ray tracing, but will quickly progress to a finished result. Producing such an image used to take many minutes (if not hours) using conventional processors, but will usually finish in a fraction of that time on the latest NVIDIA GPUs.
Note: Design Garage is recommended for GTX200 series GPUs or higher.
