[gl4java-usergroup] Is there a reason glDrawPixels() is slow on Windows . . . .

[Tobias L. G. <tg...@ul...>]

I am attempting to execute the following code:

   public void display() {

       /* Standard GL4Java Init */
       if( glj.gljMakeCurrent() == false ) {
           return;
       }

       for (int iCurrentPixel = 0;
            iCurrentPixel<maiTestPixels.length;
            iCurrentPixel++) {
           maiTestPixels[iCurrentPixel] = (iCurrentPixel*i);
       }

       gl.glClear(GL_COLOR_BUFFER_BIT);
       gl.glRasterPos2i(0, 0);

       gl.glDrawPixels(640,
                       480,
                       GL_BGRA,
                       GL_UNSIGNED_BYTE,
                       maiTestPixels);
       glj.gljSwap();
       glj.gljFree();
   }

in the display() method of a GLAnimCanvas.  This code flies on 
MacOSX(40fps), and drags on
Win32 (1fps).  I am wondering if anyone here has any idea why 2D imaging 
stuff on windows is
so slow.

All comments are greatly appreciated.

                    Peace, Love, and Hair Grease . . .
