General information before we begin: Comparison screenshots for your own testing, and what to expect. 1080P movie (Blu ray rip i made myself, so yes its a legal backup) using windows 7's codec and DXVA mode (see bottom of MPC-HC for evidence of this) If it matters to anyone, its a 12.3GB file - so its not low bitrate, or heavily compressed. You'll notice it has very low CPU usage - FYI, i'm going from 3-5% CPU usage with the show paused, due to background tasks (antivirus and such). so its very, VERY low. Now we try again with the *same codec* with DXVA disabled. GPU usage: 10% dropped to 2% CPU usage: 6% raised to 40% (varying in different scenes, but 35-40% was a clear average - you can see spikes in the usage graph as i seeked back and forth numerous times trying to get a good screenshot) Here is a screenshot of it working in windows media player. It NEEDS to be noted that for me to achieve this, i had to install the "DivX Technology preview" from their website - otherwise, i merely got FFDSHOW playing the files thanks to the CCCP codec pack i have installed, and only got software mode working.
