How to debug RDG (inspect the detail of GPU crash and CPU overhead)

Engine/Config/ConsoleVariables.ini

; Uncomment to get render graph executing passes as they get created to easily debug crashes caused by pass wiring logic.
r.RDG.ImmediateMode=1
; Uncomment to get render graph to emit warnings for inneficiencies that are normally too CPU costly, and have draw event names
; formatting even if frame are not emiting draw events.
r.RDG.Debug=1
