Most graphic cards should work out of the box. It comes with the appropriate proprietary drivers installed. To make people’s lives easier they decided to release a pre-configured Linux Distro of their own.

More games have been released on the Linux platform in past 2 years,ever since they announced their client for Linux, than in all the other past years of Linux’s existence combined. The folks at Steam have for the most part changed the Linux gaming landscape. If you don’t believe me try running XBMC on Windows and Linux to see the difference. Then there is the OpenGL issue, you would think that OpenGL would work better on Linux since it is FOSS and has an open API, but you would be wrong. I recently tried to test Linux Mint Qiana on a machine with an Nvidia Optimus. None of the Desktop flavours could start without some command line tinkering. I can attest that this is somewhat true graphic drivers for Linux often come out well after their Windows counterparts and gaming is all about graphics unless Tetrix is all you want to play. One of the reasons that is often cited for not using Linux, besides command line phobia, is that it is not a good gaming platform. SteamOS offers a complete Desktop experience as well
