Yeah, I forgot about that... CBS at 1080i is 95% ABC is about 80%
utilization when watching via MCE. I guess that MCE is a hog because
watching CBS using the Fusion software shows about 50% utilization, ABC
through Fusion is about 25%.
I believe the fusion software uses it's own decoder... so now I'm wondering
why it's so high using the Nvidia decoder under MCE?
Am I wrong in assuming that moving from the onboard 915 to the 6600GT should
result in a significant reduction CPU usage???
