I have very high CPU peaks with Waves Plugins (on tracks, master bus and so on).
I do not remember to have this before the last update Studio One Pro 18.104.22.168941.
The session is unusable except after disabling all plugins ...
My desktop is equiped with an i5-7500 with 16Gb RAM, SSD disks and a GeForce GTX960 on W10
I have a laptop Lenovo P7 Thinkpad on W10 equiped with i7, 16Gb and SSD and CPU minimum load is 40% after charged a 27 tracks session.
My audio interface is a Focusrite Scarlett SCARLETT 2I4 with the latest available driver (22.214.171.1242)
I did all steps explained on the following post but issue still persists.
I'll open a support ticket with Presonus, Waves and Focusrite.
