Playing with music visualization here, did this really simple DX11.TextureFX that copy center line on right and left, till the focus is on the patch it works great:
but as soon as I focus on other windows, or even on the desktop, the performance (and also the visual result!) fall down in a terrible way
here you got the patch and the “HorizzDiffuse.tfx”
