so let's compare systems via average cpu load in v2

on a 12core x5675 macOS system, I get 11% average load when starting vcv2 into the default patch, no audio devices connected. - macbook from early 2011 with i7 at 2.2ghz does 18.6% average load.

do the same and show me your average for your system in the top right of the screen. the one with the lowest average wins I guess :slight_smile:

edit: ok to clarify, test conditions are:

  • vanilla startup of v2.0.0 (say your version number if other than this)
  • 1 threat (no multithreading)
  • stock 30fps gui refresh rate.
  • 44.1 or 48khz sample rate.
  • load up a new patch so that no audio device is selected.

Ho many threads did you use?

that’s a waste of 11 cores

yea, looks like I can get lower average cpu hit with a little multithreading. 3 cores seems to be the sweet-spot for the default patch, tested on the macbook which has 8 threads.

not so much for the mac pro, even 3 threads increases the average significantly (2.0.1)

So I look at all these and there is not much difference. Really nothing compared to the differences from one module to another. Would do better to measure you module before you commit to them, yes?

I’ve not tried running it in the Win 10 environment.

Main reason probably being that the template patch running on 1 core isn’t really enough for modern CPUs to take notice and ramp up clock speed.

For instance, on my 3900X, while the patch is active, the core it’s tied to is barely running above idle (~1.2GHz, whereas flat out they can hit 4.6GHz)
