Try stacking a ton of really heavy plugs on one channel and you'll maybe see the ASIO meter up pretty high while your overal lsystem cpu meter is low. I think that's because the channel stack only uses one core, but I'll defer to the experts on all that.
But it seems to be possible to overload a single core while the other 3 aren't doing much of anything and (I guess) some ASIO meters read load while others mimick the windows cpu meter, dunno. It seems to confuse people, the relative comparisons of cpu meters from product to product.
Maybe the FLStudio dev guy needs to clarify all that agian, how not all daw cpu meters are the same.

simply loading cubase7 my pc fan often turns on while when i load reaper, no lie, the fan often just shuts off. i just cant grasp this. seeing how my father paid 300 dollars for artist 7.
yep, by simply closing cubase/opening reaper, the fan just shuts off.
absynth uses 8-10 percent cpu on large v5 patches but usually uses no more then 0.8-2 percent and completely shuts off/uses no cpu when not playing. its pretty cpu efficient definitely no diva. i cant figure this out.

i dont think ill sell cubase because of this as that would be stupid, but seeing as how nobody know, i guess ill use another daw till these issues are fixed and im going to contact both steinberg/n.i to find out what the hell is going on because it seems nobody knows. as beavis says, "This Sucks."

one would assume that if by adding only 1 instance of absynth and valhalla room that the cpu asio meter already shows two cores being used, one could only add 1 or at most 2 instances more before the cpu overloads.
but i realized that wasn't the case. after adding 2 instances, then 4, 6, 8, the performance meter keeps going down, to about 8 instances of absynth (with each track playing a different note with 1/4 notes in a straight line on random note so theirs no note spaces and all 16 beats being used, so as to give the impression that your actually playing it on a midi controller.
at about 8 instances of the same midi notes playing on 8 tracks cpu overload occurs on 512 samples, crackles occur at about 98 percent capacity which is very impressive with the fan turning on at 90 percent. switching to maximum 4096 buffer allows 4 more absynth instances, making that 12 tracks playing the same random 1/4th notes.
now, when talking about single sustained notes, a single note being 8 bars in length, i had about 22 layers playing the same note at once making 22 tracks. after 22 tracks, i got tired but i bet i could have added quite a few more before cpu overload.
*also, i used the same patch through both stress tests, (the absynth alien trumpet patch which is one of the most cpu intensive patches in absynth 5) with this in mind, i could have got much more instances of absynth in both cases as most absynth patches are very cpu effcient.
so now, i know that cpu is not an issue but im still unsure why occasionally(most often when adding a new vsti, or auditioning presets the asio meter spikes.
