My game uses a VolatileImage for the drawing buffer. It is created using GraphicsConfiguration.createCompatibleVolatileImage().
When the window is maximized, everything runs smoothly, but FPS drops sharply once I switch to fullscreen mode.
Is there a workaround for this? I don't want to use a BufferedImage because FPS in windowed mode decreases quite a lot if I do that.
I found a thread for what appears to be the same problem, but there isn't much relevant information in it: http://www.java-gaming.org/index.php?topic=22414.0
