Thanks for the info. The problem is that my test app works fine on a modern machine with Vista and non-opaque window mode. On an older machine with XP the app is too slow so the additional eye candy which is provided by the non-opaque window mode should not appear. That's why a auto-detection if hardware acceleration is supported would be a good feature. The result provided by BufferCapabilities seems to be good enough - I've also tested
[code] GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getAvailableAcceleratedMemory() [/code] If -1 is returned no HW-accel is supported - is the result better or equal to BufferCapabilities? AFAIK all these acceleration things are currently only supported on Windows - right?
