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 Shotcut from DirectX to OpenGL in the Display Method after that you should see the "GPU Processing" option.
Thank you, works for me!
