I downloaded the OpenGL scroll exaple and it ran as smooth as silk! It looks like you have a nice product there. One suggestion for that example: you might want to make the scrolling speed frame rate independent. It's kinda hard to appreciate the nice graphics when it's running at more than 800 frames per second .

You should let Sly of Turbo [stevewilliams at kromestudios dot com] and Savage of DelphiGamer [savage at delphigamer dot com] know about this to get your fifteen minutes of fame.
