I have 2 PC, one on W11 built with serious components (I512600KF, 64 Gb RAM, solid Gigabyte AORUS and plenty fast SSDs) and an HP 13’ spectre laptop on w10 with an I7 8xxx and 16 Gb RAM+many SSDs.
I am using Audient audio Interfaces ID44 and ID 24 respectively, we can consider they have equivalent performance.
I use a Minilab 3 to manage Analog Lab Pro standalone on them. Nothing else running.
When using the laptop, on some preset, I have to increase the buffer size of the Audient to a very large value of 1024 to limit cracks/overrun in audio output. With same presets on the I5 12600, I also have to increase the Audient driver buffer, in a lower size than for the laptop, but in a way far larger then what I have to set for other VST3 instruments.
Could Arturia do a better optimization on Analog Lab in order to reduce this CPU usage ?
HI @csurieux
There are other things to consider besides CPU/RAM/Interface, such as USB chipset, graphics and CPU throttling.
I use a USB3 interface which is a little fussy about which chipsets it will work with, to avoid any issues i purchased a PCIe USB 4 port hub, which works flawlessly.
That’s on a desktop machine of course.
Your laptop is running off it’s own internal GPU and, unless you’ve turned it off, will be throttling its CPU to some extent or another. My own hunch is it’s likely to be the USB chipset, and/or your graphics adapter on your laptop that are causing this.
It’s worth running a tool called ‘DPC Latency Checker’ on both systems to see how they compare. you can find it Here.
HTH!
Thanks @matjones but concerning my main desktop PC I have a Gigabyte Aorus Elite mobo which implements solid USB 3, no need for extension, and from my experience USB 2 has never blocked any solid audio drivers, as Audient’s one, to manage efficiently audio.
And I use an Nvidia GPU with solid performance even if I don’t see the implication on Arturia Analog Lab pro eating my CPU…
And concerning my laptop, I set its CPU mangement to use max resources, no throtling here.
And I know from years Latency checkers.
The problem is that Analog Lab is showing poor performances related to its concurrents, as Komplete Kontrol, for example, witch is not known to be a lean CPU user.
It appears that Arturia softwares should get a real pass of optimization, even if I totally support and appreciate Arturia.
