Having a real issue with media playback in Windows 8.
As soon as I fire up a game, the framerate in any media app drops to about 1fps. Sound continues fine but video is awful.
This happens in VLC, Media Player Classic-HC and playing videos in Flash like iPlayer or Youtube, so it doesn't appear that the application, render method or codec makes any difference.
I am using the latest nvidia drivers for Windows 8 x64.
I cannot find any options for this anywhere in the performance settings, power settings or graphics drivers that could control this.
This is currently a showstopper bug for me, and if I cant resolve it I'll be back to my W7 install.
Anyone have any idea what the fix could be?
