3.15 kernel has a performance regression, introduce by: http://git.kernel.org/cgit/linux/kernel/...b0b91656d5
It was well thought, but also the gpu clocks are reduced and so time intensive postprocessing (like Temporal deinterlacing) will need too long on E350 / E450 / E2000 hw. Other (faster) hw won't see that effect.
Effect for every day tasks: 1080i50 h264 won't work anymore with temporal on E-Series AMD hardware. You will get arround 33 fps. Currently talking with upstream.
