Disabled vsync: huge performance improvement! Changed ofSetDrawBitmapMode(OF_BITMAPMODE_MODEL_VIEWPORT); to ofSetDrawBitmapMode(OF_BITMAPMODE_MODEL); in testApp.cpp -> now labels of points also appear correctly in other viewports (text used to be missing). Some old code is here that was made while searching for the performance problem when a video was playing (vsync..), will be removed in next commit.
