title: JAVA 2D Game Linux terrible FameRate
body: <p>I’m developing a 2D game in java. Our group is normally developing on a Windows and Mac platform. 
  No problems appear during the game and we have a <strong>constant frame rate of 60 fps</strong>. </p>
  
  <p>Yesterday we ran our game on a Linux computer and the frame rate was <strong>only about 10 frames</strong> per second! </p>
  
  <p><em>Does anybody have heard something like this? Having problems on running Java games on Linux?
  Holding up a good frame rate on Linux?</em></p>
  
  <p>I don´t know which code lines(at the moment more then 12000) I should show you, so you could understand my problem.
  But I’ll try to explain a little of our concept so maybe you know a solution or you can give us a hint :)</p>
  
  <p>We build a Content Manager Service, which loads and holds our images which should be drawn on the JFrame. Typically we are using images in a png format. </p>
  
  <p>A very short extract:</p>
  
  <pre><code>//Load our images which are later drawn on the Frame
  URL url = this.getClass().getClassLoader().getResource( the right image Path);
  this.image = ImageIO.read(url);
  
  //extract of draw
  this.graphicsDevice.getGraphics().drawImage(ourImage, x , y , null);
  </code></pre>
  
  <p>We have about 25 different images at the same time, which are directly drawn on the graphic device of the JFrame. </p>
  
  <p>I don´t have any experience with Linux, that’s why I can´t understand the source of the terrible frame rate. (Remember, on windows and mac pcs it´s constant 62 fps, with the same code :( )</p>
  
  <p>If anybody needs some more information to help, I would try to add some.</p>
  
  <p>Thanks for reading!</p>
  
  <p>Best regards
