Video performance with GPU advantages

Hello,
I’m working in a demanding application, where I would like to work with audio, video …etc. To improve the computer performance, I would like to take advantage of GPU for the video part. That’s why I’m using videoplane instead of jit.glue to compose the output video image.
I’m positioning 9 input matrixes in one jit.window, using 9 jit.gl.videoplanes.
The Data flow goes as follow:
[Jit.qt.movie(x3)] – [switch 3 (x9)] – [jit.gl.videoplane(x9)] – [jit.window]

If you check the patch you will easily understand the goal of the application: Using a minimum number of movies, create a grid of 9 interactive zones (using different colors), with 3 different states.

It’s the first time I work with OpenGL and I have been reading the tutorials, and looking throw the forum.
I would like to know if there is any improvement I could do in my patch to improve the performance of the Computer (mainly the CPU).
I’ll also like to know, if someone thinks of an easiest way to do this application (completing the same purpose).
In my computer this patch uses 36% to 38% of the CPU.
Dual 2 GHz PowerPC G5, 1 GB DDR2 SDRAM GEFORCE 6600LE
OSX 10.4.8 MaxMsp/Jitter: 4.6.2 / 1.6.2

1. Unzip
2. Point folder in file preference
3. Copy text – File – New From Clipboard
3. Observe

Any comments will be much appreciated.
Thanks!
