1  Game Development / Performance Tuning / Re: AffineTransform with openGL Pipeline slower than without on: 2012-02-01 17:08:37
Wow,
removing this line gave me 3 more fps with openGL and more than the camera fetches without using openGL.

Unfortunately the quality is now poor.
So thank you, theagentd, this will work for my first draft.

But i'm still open for other solutions.

2  Game Development / Performance Tuning / AffineTransform with openGL Pipeline slower than without on: 2012-02-01 16:46:18
Hi Everyone,

i'm fetching bufferedImages from camera and want to scale them to whatever window-size is.
Therefore i use the AffineTransform like this
1  
AffineTransform xform2 = AffineTransform.getScaleInstance((double)getWidth() / myWidth, (double)getHeight() / myHeight);

where myWidth / myHeight hold the original Image width/height.
I draw the images via
1  
2  
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BICUBIC);
g2.drawImage(image, xform2, null);


this works fine with about 25 fps, but when i switch to fullscreen i only got about 7 fps left.
when i run the application with the openGL pipeline Option
1  
-Dsun.java2d.opengl=True
it slows down to 2 fps in small size.

Any idea highly appreciated.
