Seems like a lot of CPU reports come from laptop users. Didn’t some people say early on that the Linux version defaults to 8X oversampling?
I don’t think Vital should use twice as much CPU as Diva especially when Diva is in Divine mode.
I’m using htop (top) to get an info how much resources a program or tasks are using.
In those screenshots I only started Vital and didn’t click something in Vital
Here in Powersave mode (AC pluged in)
And here Full power 4,5 GHz (AC pluged in)
Ah hmm that is a lot higher than it should be. Vital does use a lot of CPU than a lot of synths updating the graphics but it’s lower priority than the audio thread so shouldn’t interfere with processing. Will need to see why the graphics are using a whole core in this case though…

Just two Vital in Renoise !!! I don’t know much about it, but that’s not normal ?

Hi Matt,
I was looking at the DSP load in Ubuntu Studio controls. After pressing 2-3 notes on my midi keyboard it would rise above 50% and i would get xruns. That is on 512 buffer with one instance of Vital in Bitwig and no other plugins.
My laptop is no beast but i can normally run Bitwig, 4 or 5 VST instruments, some VST effects and get by with a 256 buffer and no xruns… worst case scenario 512, but with Vital one instance is bringing it down.
If I can help you diagnose the issue let me know - if you would like me to take specific measurements or do any experiments I’m very happy to help
Hello - my htop looks exactly the same as yours when i run an instance of Vital in Bitwig… did you ever figure out a solution?
No, there is no solution yet. This is a bug and we have to wait until it is fixed.
I would love to use vital and make some tutorials, but currently it is not possible.

yes! me too!
For the record this issue involves the Linux version. It’s quite possible to use Vital to make tutorials. Just check YouTube.

It’s very variable for me. I just launched FL Studio and added 10 instances of Vital with complex patches and it maxes out at 80% Fl Studio CPU meter usage, which equates to around 15% actual system CPU usage. Definitely usable.
Other times though a single instance of Vital with a simple bass patch will exceed that usage and be borderline unusable i.e. bounce–>delete is the only option.
I really hope this is something that can be fixed because Vital has lifted my game and I want to smash it on every track!

Yes, thi seems r to be an issue with the Linux version
Sorry, that’s completely wrong.
If you read this thread and discord, you would have noticed this issue is as well on Mac and Windows. So please don’t spread spontaneous myths.
Even most of the people who made tutorials , didn’t tell about the CPU usage. So if you own a monster CPU and GPU you are fine. If you have a standard system and not fitting into a, not yet figured out optimal configuration, you have this problem.
So please read and research, before claiming some unproved myths. Thank you.
Same goes to you.
No problem with CPU on Windows here. Sure Vital can use some CPU when you push it but then the same can be said for most modern synths.
The majority of the complaints come from people who are trying to run a modern synth on legacy systems.
You said it’s not currently possible to make tutorials with Vital. Obviously that’s incorrect as witnessed by the numerous tutorial videos found on YouTube. It may not be possible for you but it is obviously possible. So please read and research, before claiming some unproved myths. Thank you.
The Distortion, EQ, Flanger, and Phaser effects seem very expensive when selected even if they are deactivated. Any of those sends the pool thread to 100%.
Please … just don’t talk against a problem you don’t have. My system is 1 year old. Yeah very “legacy system” irony . If you don’t have an issue, be happy and please don’t 'splain about something you can’t retrace.
We try serious to trace and solve an issue here.
Thank you very much.

Please just stop claiming some unproved myths. I originally responded to your incorrect statement above. Once again it is entirely possible to create Tutorial Videos…on many systems…as proved by the abundance of them on YouTube.
The fact that you can’t make them on your system is another issue altogether.
So “very high CPU on some Linux systems” may be true but it’s not true for all Operating Systems and all system configurations. That’s the point I’m trying to make. Nothing more.
I ask you very kindly to stop trolling this thread. Thank you.
I’ve got all the info I need for this so am closing the thread.
