Valve recently announced that it will be bringing a few of Steam's most popular games to Linux, the first of those being Left 4 Dead 2. But besides the novelty factor of running the now classic zombie simulator on penguin-emblazoned hardware, there may be another reason to try the new platform out: It'll be faster. Even now, during development, the Valve team has L4D2 running at 315 frames per second on the Linux text platform, as compared to the standard Windows speed of 270.6 FPS.
At that point, of course, the speeds are mostly arbitrary. But as Valve says, this speed shows the potential in customizing a game for the Linux operating system. This work on Linux is also benefiting the Windows teams - in working on the Linux version, Valve was able to speed up the OpenGL implementation on Windows to 303.4 FPS.
