Yes

Clear. I'll add scaling to 10359_controls.

They are taken at the same time (from the same trigger).
While one going through directly, another is being buffered and after the first frame is done the read from the buffer starts. And as 1296x960 allows ~44fps the vertical doubling will make it twice less.
