RAM spikes when opening project


I’m running a medium sized orchestral template all within cubase. When loading this template ( empty or from a specific project i’m working on) i get ram spikes (99%) when the project is first opend, after a while (when i have played the track about 2 a 3 times true) it drops back to around 50%, wich is normal.

Could this be kontakt related or could it be a bottle neck somewhere else?

My pc specs are:

Windows 10 professional
Intel i7 9600k
64 gb ram ddr4
Os on a hd 7200 rpm
Samples on an ssd true sata 3

Any ideas?
Thanks in advance

Hi and welcome,

After opening the project, wait until all samples from all libraries are loaded, please.
