steinberg power scheme and cpu core parking ?

it’s not only the cakewalk forum that is suggesting to use it

A forum doesn’t suggest anything in that sense…what you mean is a person who posted on the forum suggested it. This is no different from saying my mate down the pub suggested it. Doesn’t qualify it as good advice although I’m also not saying it’s bad advice

FYI it was on the cakewalk forum that cakewalk themselves said they had tested and found no difference.

but it is stated as not usefull for win8…
confusing…

Doesn’t seem that confusing…you’re on Win8 + it’s not useful on Win8 = stop worrying about it and make some music.
