Thanks a lot, very interesting data :) The "old" X11 pipeline (Linux, no OpenGL) has quite a hard time with modern drivers, with the upcoming 180.* drivers you'll see even worse performance.
I am working on a new pipeline, improving the performance of non-opengl rendering on Unix: http://linuxhippy.blogspot.com/ > There is no pixel-to-pixel correspondence when Qt > OpenGL pipeline is enabled (I have taken two > screenshots, there is only a subtle difference).

Hmm, I am not from Sun so I don't know why Java2D doesn't offer such a quick&dirty mode. It would probably quite useful for games - however games often use pre-rendered images anyway. However to be honest I was quite disappointed about the quality QT+OpenGL shows on your screenshot. It was my belief that modern hardware (like your GF7) in combination with latest drivers would behave much better from what I have seen from 5-year ago hardware, but still quality isn't reliable. Its ok for games, but would you really build a user-interface on top of that, where you have a lot of tiny lines and small primitives? - Clemens [Message sent by forum member 'linuxhippy' (linuxhippy)] http://forums.java.net/jive/thread.jspa?messageID=319269 =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA2D-INTEREST".
