"Among the modified files are some Linux-related files including a hardware driver compatibility list, optimal graphics settings, and a shell script launcher (previously only for OS X, now with a case for Linux as well)," writes Slashdot submitter spacenet.
Valve have only acknowledged the existence of this update in a forum post , but not its content, and have yet to update the changelog. Hm! Hm? Hm.
This comes on the back of Valve's announced Steam for Linux private beta , which was said to be going live this month - but has yet to emerge. The interest in Linux also mirrors the inroads the platform is making on Mac - anything, it seems, to put distance between itself and the Windows 8 " catastrophe ", as Gabe Newell put it. Can Valve single-handedly usher in a future in which PC gaming is no longer largely synonymous with Windows-gaming? Putting Team Fortress 2 on Linux is certainly a big step in that direction.
