ofxOpenNI performances

HI,
even on a very simple test code, just showing the depth view, on a notebook with i7 cpu and windows7, Of goes
under 15 fps, for sure there is something weird, somebody had some hints or experienced the same problem?

thanks in advance,

Luca

I’m on Linux with a core2duo 3ghz desktop and I roll 60fps and use ~10% of one cores cpu.

Something is weird…

for sure, but the code is so simple, that i cannot understand what can be wrong,
I have OpenNi 1.3.3.6 and NITE 1.3.1.5

  
  
void testApp::setup()  
{  
	  
	playContext.shutdown();  
	playContext.setup();  
	playDepth.setup(&playContext);  
	ofSetFrameRate(60);  
}  
  
  
//--------------------------------------------------------------  
void testApp::update()  
{  
	ofBackground(255, 255, 255);  
	  
	playContext.update();  
	playDepth.update();  
	  
}  
  
  
  
//--------------------------------------------------------------  
void testApp::draw()  
{  
	ofSetColor(255, 255, 255);  
	playDepth.draw(0,0,640,480);  
	ofSetColor(0, 0, 0);  
    ofDrawBitmapString("FPS : " + ofToString(ofGetFrameRate()), 10,  ofGetHeight() - 20);  
	ofSetColor(0xFFFFFF);  
	  
}
