It should be automatic -- it's an API designed to drive hardware. It's possible that some implementations of off screen rendering do not use the GPU. (This would mean that some systems benefit from hardware acceleration with off-screen rendering while others do not, even though both contain hardware which could support that rendering.) That said, until someone finds a solution, there isn't much benefit in trying to describe that solution. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
