To DXVA2 or not!! - mrhyde1969 - 2012-02-16
Hi,
I am running a HTPC with a GT520gpu and an i7 cpu running Win764 and the latest XBMX Beta3 with HD audio and was wondering if there is any advantage enabling DXVA2 or not? Does it give better picture quality?
I dont seem to notice any difference myself apart from perhaps when I chapter search it seems a little smoother with it disabled...

If you don't need help from the GPU (which you shouldn't with that rig) then call it personal preference.

DXVA is hardware accelerated decoding, has nothing to do with chapter search - which has nothing to do with decoding video.
While you don't need DXVA you can use it to lower your CPU power consumption, and heat.
In general, your system is overkill for HTPC. If you are only using XBMC you have about 10x the machine you really need.

Chapter search is smoother when I use my CPU for decoding, dont know why but its a fact.. Yeah i know its a bit OTT for a HTPC but I also use to have a GTX580 in there also only got rid of that because it wouldnt 'bit stream'. It was originally built as a gaming rig, but found myslef bored of PC gaming so i just turned it into a HTPC
I was just wondering if eneabling DXVA2 had any other advantages apart from taking the strain off the CPU. When using DXVA2 my cpu is running about around 3% without it it runs at around 7% ( blu ray rips )..
Thanks anyway
