I would like to recommend Phoronix readers to test From Dust on Linux:
I realized that Phoronix doesn't like to cover Native Client titles on Linux, but in my opinion it is the best way now a days to convince large studios to bring their title in a way that it can be played natively on Linux.
Depending on how you see NaCl, you can say that Ubisoft has ported on of their title to Linux. It is very cool to get developers involved in this Google project, since it uses 100% open source infrastructure to build games to run inside the browser.
NaCl's compiler is a modified version of GNU GCC.
In my opinion, once a developer ported it's title to NaCl, it need only couple of steps to create a native Linux port.
I think that with some command line options on Google Chrome and a special extension installed on it, it should be easy integrate it on PTS, for more interesting benchmarks, since today we have a very large selection of 3D content that is running on the browser, through both: WebGL and Native Client.
