Re: Questions about gnome-mag + orca

["Aurelian Radu" <ricaradu gmail com>]

Thank you, Carlos. I am replying to your email using compiz-fusion (the CPU usage barely reaches 3-4%. It would be great if gnome-mag were as easy on the CPU.

When you say that the algorithm can be calculated in the GPU, you mean there is a setting I can change to do that, or is this a feature that needs to be implemented?

Thank you,

Aurelian

Hi Aurelian,

Probably in a Core 2 Duo you will have 50% of CPU usage (100% of one
core). This is not a bug, this is due the fact that the magnification
algorithm is CPU intensive. This can be solved using the video card
processor, that is by far fastest for this type of operation.

If you pan a lot this will probably heat and battery life.

I'm not developing gnome-mag anymore, but probably the GNOME Outreach
Accessibility Program will adress these issues, but I think that this
will take a while, one or two GNOME releases.

Best regards,
Carlos.
