I am currently using Shotcut 17.10 x64. My graphics card is a Radeon R9 390."GPU Processing" does not appear to be an option in the "Settings" menu.
Option is there for me in latest version.I use an R7 360 card.
Which OS are you using and have you the latest drivers installed?I use W10 Pro 64
Mine is missing also. And this could be what is causing my sync issue on exports.
@ThaPeaceMaker and @luketomaneng you need to change Shortcut from DirectX into OpenGL in the Display Method that should fix it.
