Sorry for the potato quality, as I mention in the video, I had to nerf the encoding settings to be as light on the CPU as possible, since the GPU shares its bandwidth. The video looks jerky, but the frame delivery was consistent and since my monitor now has a FreeSync range of 40-144Hz; and the little Vega 11 was able to keep it over 40 almost all of the time, it was smooth.
