I always use purge all samples at the beginning.
Even after finishing a track I use reset market, then play once through song, then use update samples.

 

Start doing the same after i found out about it
been using kontakt for a good while and realy should of looked into it sooner,
purge is more for saving ram do. have added a vid here about saving cpu this one i new abit more about.

Thanks metaller but it doesn´t really give you "less cpu usage" does it? I´ve just tested this and I´m having the same amount of cpu use with or without it.

 

to reduce CPU/RAM usage I always freeze the tracks that have many plugins loaded & I'm not currently working with. then unfreeze if I want to make changes to the tracks. It's quite inconvenient, but better than having some latency issues & crackling noise.

Not much, but may help because the Kontakt needs to think about a limited number of samples.

Kontakt CPU usage depends highly on the script and effects and number of samples used at a time for each note.
So, bypass the effects you do not use from the actual nki setting button (goes into instrument itself for Kontakt full).
Also disable multi-core support of the Kontakt, if you daw support multi-core support.
In addition, increase the CPU protection from the Kontakt settings.

If you really need to make the CPU usage zero, just freeze or transform it to audio.

 

What about Kontakt Memory sever ?
