Hi,all,
currently ,I am trying to read the source code of UE4.6.1. when I gone through the code regarding rendering, beside the rendering thread,I have found there is a thread called RHI thread with its own command list.I have read the document about the “graphic programming”.but it say nothing about it,is there some one can tell me the role of RHI thread and difference between RHI thread and Rendering Thread?
Thanks in advance!

Thank you for reply,but how to compile the source code make the RHIThread actually work.is there any preprocessor macro defined to enable the feature?

Will the RHI threading be more useful in DX12? I notice that DX12 mentions some optimisations provide a ten-fold increase in the number of polygons that can be handled - would that be related to fixing that botched threading?
