1. AMD E350+HD6310 (iGPU)- stutter when playback blu-ray disc (1080P video/bitstreaming HD audio) directly on BD-ROm or ISO using W7+XBMC
2. AMDE350+Nvidia GT430 (discrete GPU)- no stutter when playback blu-ray disc (1080P video/bitstreaming HD audio) directly on BD-ROm or ISO using W7+XBMC
Playback rely heavily on GPU......after GT430 is installed, I can playback every blu-ray disc I threw at it fluently and streaming Netflix HD is fine too......
Let me ask you this again- Have you try to playback blu-ray disc (1080P video/biststreaming HD audio) directly on BD-ROM or ISO with E350+HD6310 using W7+XBMC? If you can playback fluently, good for you.......
Frankly, no, I'm not going to download 50GB to test your theory when no one else is able to replicate your issue and you are unable to explain how the issue you see could even work. 'Playback rely heavily on GPU' well, only the video decoding part. The GPU can't do anything else, it doesn't decode audio, it doesn't decrypt the the disc, it doesn't do anything other than decode the video and draw the image on the display. I can decode demultiplexed Blu-Ray h.264 [email protected] streams with 7.1 audio no problem. You don't even clearly identify your 'challenge' when you say 'BD-ROM or ISO' you don't even specific if you mean decrypted media or encrypted media.
I don't even understand why you feel the need to specify bitstreaming of HD audio. That actually makes it EASIER for the hardware. BitStreaming means the machine doesn't have to DECODE or PROCESS the audio, it just need to transport it out the HDMI port to the external decoding device. It doesn't have to do ANYTHING but push up to 18mbps of unprocessed data through the HDMI cable. Frankly, and I'm not trying to be insulting, I don't think you actually understand how this technology actually works.
Please, feel free to make a logical explaination as to why the method that the data is stored would somehow drive up GPU demand for video decoding and be resolved by a more powerful discrete GPU.
