Games From Valve's Linux blog: "That the Linux version runs faster than the Windows version (270.6) seems a little counter-intuitive, given the greater amount of time we have spent on the Windows version. However, it does speak to the underlying efficiency of the kernel and OpenGL." If it wasn't obvious before, it should be now: Valve has started its marketing campaign for Linux. With the Windows platform in the process of closing itself off, Valve has to look to greener pastures. This is all to motive third parties to get their stuff ready for a possible Linux-powered 'Steambox' - not a console, but a set of generic PC specifications. Remember: the Xbox is the only machine tied to DirectX - OpenGL runs everywhere else, including Windows (the PS3 is an oddball, and has a sort-of Sony-specific FrankenOpenGL). OpenGL simply makes more sense for developers, and now Valve is working very closely with Nvidia, AMD, and Intel to optimise their Linux drivers. Do the math, people.

My main point of my posts though was that the performance benchmark wasn't necessarily fair to Windows Vista and 7 regarding games, because the Direct X 9.0c api is about 8 years old and just doesn't have features that take advantage of more modern hardware.

I think a Direct X 11 vs OpenGL test would be more interesting if at all possible.

The benchmark is not about fairness, it's about the performance of the Linux port of an actual game.

But anyway I don't see how the test is unfair: they are comparing a DirectX9 implementation with contemporary OpenGL.

I very much doubt they have updated their OpenGL implementation when they didn't bother going with anything newer than DX9.

And no one is saying that you would get the same results with OpenGL4 vs DX11 anyway.

It'd be interesting to test the improvements made by GPU vendors using something like Unigine. There was a benchmark at TomsHardware where Ubuntu 11.10 scored below Windows7 on average (with a difference below 10 FPS) but it still beat DirectX11 in two of the three Unigine benchmarks when using AMD drivers.
