 ## Suggested Exercises
+After building and running the code, first thing I recommend you do is load up the Nsight Graphics project file (IntroToDXR.nsight-gfxproj), and capture a frame of the application running. This will provide a clear view of exactly what is happening as the application is running. [You can download Nsight Graphics here](https://developer.nvidia.com/nsight-graphics).

 Once you have a good understanding of how the application works, I encourage you to dig deeper into DXR by removing limitations of the current code and adding new rendering features. I suggest:
 
 * Add antialiasing by casting multiple rays per pixel.
