Just a few weeks back though I reported that GameTree Linux was still not yet to be found. TransGaming was pushing GameTree TV higher than the Linux-desktop-focused version, but now we are starting to see the first signs of GameTree Linux software.
The GameTree development portal is now open and within the Linux center it provides a few more details about what this TransGaming endeavour is all about.
The Linux software is described by TransGaming as "a suite of developer tools powered by Cedega technology that enable Windows-based games to run on Linux desktop systems. With minimal effort, developers can run their OpenGL or DirectX Windows games in a Linux environment."
GameTree Linux consists of the GameTree Linux client, Cedega-powered engines, and documentation.
There aren't any titles out yet though actually leveraging GameTree Linux, but interested developers can join here.
