If your CPU is too slow for HD playback (720p and 1080p), there is a way for fixing it, without making any hardware upgrades. Reading this article, you will learn, how to make your video card's GPU do video acceleration instead of your CPU. That increases video playback performance immensely and takes quite some workload off your CPU.
Video card manufacturers have been embedding video decoding codecs in their cards for some time now, but if you want GPU accelerated HD video, you need at least an ATI Radeon 3000 series or Nvidia Geforce 8000 series ( GTX 640/320 and older excluded). This can also be done on laptops, if you have a dedicated video card and not integrated graphics. Follow instructions:
Extract it somewhere on your drive (you will need WinRAR for this).- Go inside "mpc_gpu" folder and run the executable "mpc-hc.exe".
- A quite old-school looking player will open, but it is one of the most powerful. Before using it for x264 playback, you should modify one option. Go to "View"- "Options". In the left field select "Playback" and after that "Output". All you have to do is change DirectShow preference. If you are runningWindows Vista or Windows 7, please change it to "EVR" and if you are running Windows XP, change it to "VMR9 (renderless)". After that click "Apply" and you are done.
- Now you can watch HD videos and your GPUshould be doing the work. In all other video players settings will remain unchanged- no GPU acceleration there
Some netbooks already support GPU video acceleration and can play HD videos smoothly even though they are based on a power-saving Atom processor. Such example is HP Mini 311-1000NRwith 6.25 hours of battery life.
