Hi,
Thx for the info.

I would like to ask a question regarding contour please.
Why is it that it only uses 30%-40% of cpu power, thus making it very slow.

And is there a way to improve that?

Thanks in advance.

Can you ask this as a new question, please?

[AbouMay]

I did, but there is no engagement.
I'll post it again in this new form, I hope you'll be there 🙂
