  1. For Nvidia: extern "C" { DWORD NvOptimusEnablement = 0x00000001; } This does work on Optimus setups as far as I know. You need to make sure that it is included into the binary, the easiest way to do so is stuff the line into your Main.cpp or equivalent file.

    Fast ray/cube intersection in shader

    Check this out. It was written for SSE, but since it is branchless it should work in shader. https://tavianator.com/fast-branchless-raybounding-box-intersections/ https://tavianator.com/fast-branchless-raybounding-box-intersections-part-2-nans/
  3. Has anyone found a way to measure time to render a frame? Due to flip_sequential, I only get 60 fps even with Present(0,0).
  4.   Hold on, what happens if you have more than one command queue?
