ExecuteCommandList must be executed on the immediate context for recorded commands to be run on the graphics processing unit (GPU). Use the immediate context to feed commands to the GPU for execution, use a deferred context to record commands for playback onto another command list. When you call ExecuteCommandList onto another deferred context, you create a ‘merged’ deferred command list. To run the commands on the merged deferred command list, you need to execute them on the immediate context.
