Why is my cpu usage so high. With 2 different asio drivers my my cpu usage according to the meter in the tool bar is always in the 70s or 80s. I set latency in both driver at 384 but the meter still rates high usage. In the windows performance meter I am never using more than 20% of cpu. With memory usage at about 25% of the 4gig I have available. My processor is a amd phenom Quad core. When I switch to mme drivers the usage is only about 40s on the toolbar but remains the same in the windows resource meter.
