Direct 3D 11 Shader Debugging with NSight
I am trying to debug D3D11 shader bytecode without source. According to this page: https://ift.tt/2uBzOl7 This should be possible, under 'Byte Code Debugging' However it doesn't actually say how to start debugging them. I Ctrl-Z the app and hit Space to capture a frame. Then in Windows->Shaders I choose the pixel shader to debug (while having the draw call that uses that shader selected in the scrubber). The next step it says to choose Windows -> Choose Graphics Focus, but that doesn't exist in the latest version(?) I can set breakpoints in the shader bytecode file that comes up when clicking through to the shader, however they are never hit. What am I missing? Has anyone successfully done this? Is there any software you can debug/breakpoint shader bytecode and see registers after each instruction etc?
