My observations of both Linux and ReactOS suggest that ReactOS is better for gaming, especially 3D games. Full-screen animation on Linux is really slow and choppy, and this is true for every graphical Linux OS I have tried. ReactOS on the other hand has seamless full-screen 3D animation, if the screensavers are any indication. What are your observations? Have you used ReactOS for gaming, or have you found a Linux distro that has good full-screen animation?
