FL Studio 9 - CPU bleeding?

I'm not sure this is the right section for this, but I'm having trouble with FL Studio 9.

Whenever I use the program to play anything that's over a few seconds long FL Studio starts to suddenly take up heaps of CPU without me knowing why. Is there a way to prevent or fix this?

Make sure to use Asio audio driver (option --> audio setting)

Afterward if your CPU is still used up, it is because the number of sample your project is using, render some into waves and free up some memory. (Kontakt 4, Guitar rig 4 are CPU devourers)

Actually I would do that as a ast resort.
here is what I do:

I do not use ASIO unless I have to record. Instead I use native sound drivers / primary sound drivers and then I increase the buffer lengh to a maximum.

also you should turn of the streaming of long audio from the disk, unless yu have audio so long, that your memory capacity is jepordized.

Now that your cpu peaks can have two reasons:
buffer overloads mean that the processing of your song in the preview takes longer than playing it, so it starts lagging and using up a whole bunch of CPU ressources.

also you might be using to powerfull plugins that suck your processor dry.

These two problems may be connected anyway though.

Look up what plugins you have.
The one plug-in I know, that causes the most CPU drain is "Hardcore".
So while writing my songs and playing them in FL Studio I tend to turn it off and then turn it on for export.
