SceneInFlightFramesCount Property

InFlightFramesCount represents the number of command buffer and buffers for scene and object data. This value depends on SwapChainImagesCount. When SwapChainImagesCount is 1 (used for SharedTexture or WritableBitmap) then InFlightFramesCount is also 1. When SwapChainImagesCount is 2 or 3 then, by default, InFlightFramesCount is 2. In case when SwapChainImagesCount is 3 or more, then you can set InFlightFramesCount to 3 by setting PreferredInFlightFramesCount to 3. This may be beneficial when recording of the command buffers takes a long time. The current in-flight frame index is set to CurrentInFlightFrameIndex.
