For an installation I am running an app on a mac mini without a screen. For tracking users i use ofxOpenNi.
Everything works fine just until ofxOpenNi detects a user. Then everything just gets terribly slow.
If I attach a screen or connect to the mac mini through screen-sharing, the app speeds up to normal speed again until I disconnect.
If I set vertical sync to false, things seem to be a bit better. I only have to connect once to the mac mini to get rid of the framedrop and if I disconnect again, the app stays at its normal speed.
But since the application should start up automatically, this would be no option.
If I start my app in fullscreen mode, every thing seems to be normal.
Can anyone point me in the right direction?
