[PD] Working RPI Soundcards (was raspberry pi user experience)

[Alexandre Torres Porres]

by the way, since I've been abusing so much of the GUI to build me fancy
interfaces, I can see how easily it can choke on its update and flood the
CPU.

Now, could an external video card help on that? What is the issue?

I'm using a macbook air and I see that the video processor is built-in the
CPU or something like that, hence no proper videocard. I figure the RPI has
gotta be something like that.

So, does it mean a macbook pro or other laptop / computer with some badass
video processor or card can run the patches better even with same clock?

thanks
