Everyone a great god ask a question, can write a dx12 example recently discovered efficiency without its efficiency is high, basically sent five times, research for a long time don't know what causes,
Low efficiency of the API call display CPU time is too high, the GPU elapsed time basic is consistent,
Occupy higher API is as follows:

Dx12:
Average ExecuteCommandLists occupy 0.08 MS
The Present average occupy 0.34 MS
PCommandList - & gt; The Reset () 0.06 MS

Its:
The Present occupy 0.11 MS
DrawIndex occupy 0.02 MS

Obvious dx12 call takes time than its make a lot of, you have the same problem? Please feel free to comment,
