Very High CPU Usage

[tylerwmarrs]

Would you mind sharing the source to create the model? It seems that it is saved to use all CPU cores available. I also had issues with the hardcoded "/dev/video0" in the snap package. Once I checked out the code and edited it, I was able to get it to work. This is simply due to me having multiple cameras set up.

Adding an option to choose the camera would be good.

CAn confirm the issue having similar problem on archlinux although even with single camera model is not minified and it uses way too much CPU and do not use GPU at all.

I've added more GPU capability in the beta release, which will eventually become stable once I've verified everything works correctly. You can give the beta a try by running:

sudo snap refresh --beta fakecam

If you have uninstalled the app, then replace refresh with install in the command to reinstall it from the beta channel.

I had a similar issue with CPU over GPU. I refreshed to --beta. The video in the beta version freezes after a couple of seconds.

very strange. I uninstalled the beta and reinstalled the stable, and now the performance is even worse (more CPU heavy) than before.
at first it was using ~25% of all 24 threads, now it is taking up ~80% of all 24 threads and camera frame rate is very slow.

Ah, ok the performance is better (~25% of all threads) with an image in the background vs having the blur effect (~80% of all threads).
Still does not seem to using GPU:
