Others reported it as well but I wanted to document my success as well. When I moved to a Full HD tv I found that I have to move away from XP to windows 7 in order to get decent hardware acceleration out of my integrated graphics. Because of power and heat I didn't want to use a dedicated card. Now I moved the whole setup on a new disk and decided to try windows 8 consumer preview.
- Gigabyte GA-MA78GPM-DS2H motherboard (AMD 780G +SB700 chipset,
- AMD 4850e dual core energy efficient cpu
- 250Gb hdd (all media is stored on a NAS)
- 6Gb RAM
Windows 7 was running everything fine, including high bitrate full hd mkv's (which failed on XP)
In windows 8 everything including hd worked out of the box, without installing any drivers. Still after installing the Windows 7 graphics driver found on AMD-ATI website performance is even better.
The system boots fast, xbmc works wonderful. Also the darn metro tiles look pretty good on a big screen - actually I hated metro on the desktop but on a big screen they look at home.
