How about a "debug" mode (set in Cakewalk.ini?) where we can get more detailed CPU usage. This would be great when measuring the amount of CPU used by various plugins, or settings etc.
Even if these meters added a little overhead (to the CPU), they could still be used to measure "before" and "after" measurements.
Then we could go back to "normal" settings - for normal use.
At the moment - Platinum doesn't seem to pay attention to CPUMeterMode= settings in Cakewalk.ini.
