bluray Wrote:If you understand the purpose/function of DirectX Video Acceleration (DXVA), you should know why HTPC users uses it. But here is short explaination on it-
My wife and kids like to do multiple tasks in the background while watching movie on their i3 PC, and DXVA is a great option to maximize CPU usages. DXVA function is primarily use to reduce the workload of the computer’s CPU, allowing the computer to execute other functions more efficiently. DXVA is available in most major media players and GPU's....
Bluray, I know exactly what DXVA is, so please don't patronize me. If the PC was busy enough that it did not have the 20-30% CPU available to run XBMC smoothly then I have serious doubts that DXVA would make much of a difference.
I think that you should be willing to admit that most users who turn DXVA on
1. don't even know what it does.
2. turn it on because it's there.
3. don't understand that in some case it can make things worse
Intel i3 cpu can decode full BD using about 25% cpu power. That doesn't leave enough for "background tasks"? What are you doing, encoding movies in the background? If that's the case, I suspect that your usage is not typical of most here, who simply want to watch a movie smoothly, which the intel CPU can do.
