you just brought to me the insight why the game developers use d3d. because they do not care if it runs in some years, they make the money now. they see how much does the development of the game cost and how many boxes can i sell in short time. so they choose the most widespread platform, which is windows and use d3d which seems easy for development and looks good. result are games like crysis and so on. downside is as you said, the different d3d versions do not run on any windows but the newest opengl does. maybe an argument for game developers to bring the best graphics to any windows with opengl and maybe with osg. ;)

in industries like the movie industries it is different.
[quote]In the film industry, Linux has won. It's running on practically all servers and desktops used for feature animation and visual effects. LinuxMovies.org met monthly in Hollywood for years, but now rarely meets.
Linux is used to create practically every blockbuster movie in theaters today, movies produced by Disney/Pixar, DreamWorks Animation, Sony, ILM, and other studios.
Linux is the most popular operating system for big budget feature film animation and visual effects, with more than 95% of the servers and desktops at large animation and visual effects companies. People outside the film industry, and even inside the industry sometimes, don't realize that Linux is so big at large studios. Linux is the norm in Hollywood and considered the state-of-the-art. In this upside-down world where Windows and Mac are minority operating systems, Linux evangelists would be hard-pressed to find anyone left to convert. The free operating system built by the people for the people has been embraced foremost by film studios.
Hollywood prefers Linux because in the right hands it's better, faster and cheaper. At large companies that have thousands of servers and desktops, the economy and massive efficiency of Linux is felt most. At smaller production companies, Windows or Macs are often more popular because economy of scale doesn't apply. Despite that, some small shops run primarily Linux. Some production companies use a mixed environment. For example, South Park is produced using Mac desktops with Linux servers. Although king in the film industry, Linux is rarely seen in the television industry due to much more modest computer needs.[/quote]
