   I think this is normal since the run time refresh rate is much higher than the adapter's refresh rate, which on my laptop the adapter's refresh rate is 60FPS, you may put the render thread to sleep a while to stalling to submit commands to GPU, which may alleviate the flicking issues. By the way, other samples still suffer the flicking when FPS is two high.

   @TaylorSevens, thanks :D
   I was wondering for a long time why I had this problem and thought that I have problem with my GPU drivers.

   @BrennyBear, try to run in release mode. That worked for me.

   @TaylorSevens, I am curious about the reason for screen flickering when the run time refresh rate is much higher than the adapter's refresh rate. Could you give me some explanations or links to related articles?

   Actually, there is no problem because flickering is a window adapter behavior, which conerned to swap chain. you can turn on vsync to limit swap chain sychronzing frequency to below 60fps, refer to MSDN swap chain creation flags:
