bluray Wrote:I'm not sure that it is worth mention in here. I tried to playback a newer "Contagion" blu-ray disc on 4 PC's with Intel i3/E7200, AMD APU/X4, Nvidia and HDxxxx GPU's for the last several days. All CPU's/GPU's suffered severe video frames drops and Macroblocking. AMD/Nvidia GPU suffered video frames drops every 7 minutes (5-15 seconds each time), and i3 iGPU got the worst of it because it suffered video frame drops every 30-40 seconds (5-15 seconds each time and it's not watchable). I was able to finish the movie with AMD GPU. What I'm trying to point out here is- it could be blu-ray movie related too. I thought it was a bad blu-ray disc, but it happpened the same way with both Redbox and Netflix discs on the same movie.
My conclusion- i3 suffered the most frame drops when playback "Contagion" using both Daniela/DDDamien XBMC builds and TMT5 as an external player. Since AMD and Nvidia GPU's suffered frame drops every 7 minutes, it was watchable. I don't have the same problem with my other BD's. It was a weird experience to say the least!
My conclusion is that you have DXVA turned on in the i3 setup or you don't have the current drivers. The i3 does not have any more frame drops than the ATI does and it does not have macro blocking with DXVA turned off (and there's no reason to have DXVA turned on since the chipset does not support it and the only benefit of having it turned on is saving about 5 watts of cpu power).
This is getting pretty seriously OT so if you'd like me to quantify these differences for you then we can take the discussion to the appropriate forum.
