Hi everyone. I'm totally new to MadMapper, I'm currently playing with the demo before I make the decision to purchase it. I was wondering what kind of advice you might give in the situation I'm describing.

First of all, I'm running:

2012 MacBook Pro
2.9 GHz Intel Core i7
Intel HD Graphics 4000 1536 MB

I have plenty of experience in general video, programming, openGL, etc. I'm using openframeworks, using syphon to pipe in a silhouette that I'm grabbing from a Kinect, and also sending a fog effect that I've created in GLSL. Essentially I have a simple Kinect effect being mapped onto people on a stage, a fog texture that is projected, and then a looping video background behind everything.

All of these work individually, and I don't get the sense that they are too much to run at once. What I didn't expect was a significant slow down when simply sending multiple textures via syphon, which I'm beginning to be concerned with. If I have to, I can prerecord the fog effect and just not do that on the fly, really just leaving one syphon input and two video layers.

Does anyone have any thoughts or advice on me taking this on? I'm working with a relatively tight deadline, so I thought I'd see what others think. Thank you!

I already tried getting Syphons from Modul8, sample Client Application, VDMX and Arena at once with 60 FPS
But with an nVidia card. Intel HD graphic drivers are very bad on OSX...

1- Have you tried running OpenGL Driver Monitor to see if you reached the GPU usage / VRAM usage ?
2- In what resolution are your syphon Streams ?
3- Have you tried collapsing previews ? (menu View / Collapse Views) Previews are consuming GPU too, and might not be useful in your case.

To view your FPS, you can type that in Terminal:
defaults write com.garagecube.MadMapper logenabled 1
defaults write com.garagecube.MadMapper logFPS 1
Then restart MadMapper, it will log the FPS in the Console (FILES / ~/Library/Logs/GarageCube/MadMapper/...)
