Hmm, that's a good question. I couldn't find anything about that on the project page.

Well, as the SWT3.2 is still being developed there still is a chance that this one appears in the final release.

vsync doesn't make sense in windowed mode

So is there other way to have smooth animation in the windowed mode ?

What do you mean by "smooth" animation? You shouldn't need VSync enabled to do animation that is at least 30fps (My definition of smooth :D )

My definition of smooth is 60fps :twisted:

For a maximum of 100 fps with very low polling overhead, use a looping timerExec() call like the following:

Code Select


    display.timerExec(0, new Runnable() {

      public void run() {
        render();
        display.timerExec(0, this);
      }
      
    });

This has a maximum of 100 fps because the timerExec() has a minimum resolution of 10 milliseconds (at least on Eclipse 3.2M5a, Windows XP). Results may vary depending on the complexity of your scene and speed of your graphics card. For my small test scenes, 100 fps is achived with almost zero CPU cost.

Greater than 100 fps can be achived by using display.asyncExec() and the high resolution timer, org.lwjgl.util.Timer. However, CPU overhead will be incurred from polling the timer.
