I tried to run some of RasterTek's DirectX 11 tutorials using the obsolete DirectX SDK (June 2010). When I run these tutorials (as-is) my screen becomes completely black on my notebook (i.e. so no visualizations). My notebook also seems unresponsive for a few seconds while pushing CTRL+ALT+DELETE. Finally, CTRL+ALT+DELETE works and after re-clicking the application icon (so that it has focus again), the application and visualizations work fine.
Any ideas why this does not work out of the box?
