I've searched, but can't find a solution (though I suspect it's here somewhere). I have an Intel p8400 (dual core, 2.26 ghz) with a Radeon 3650 (512 mb) and 4gb of ram and I'm running Vista 64 bit. My CPU runs at about 2% at idle. Running Silverlight (4 or 5) streaming SD, I'm not dropping frames, though the CPU is in the 80s. In HD, however, I"m getting about 1 fps (1 rendered/20 dropped) and the CPU runs at close to 100%.
Is there any reason I should be having problems streaming HD given my hardware?
Thanks for any help.
