Games run faster on SteamOS than Windows 11, Ars testing finds

The amazing thing is that there is often a translation layer involved and it still runs faster. And as it was pointed out, this can also be achieved with a "normal" Linux system.

Linux runs games faster even outside of Steam OS.

That's just a stupid claim, SteamOS is Linux based, and every Linux distro generally have the same optimizations SteamOS has.
Windows is simply not as efficient as Linux is.
For instance multi threading has traditionally worked better in Linux, but there has also been made massive improvements in the kernel to improve graphics card performance, with entirely new technologies introduced a few years ago to achieve that.

These things also benefit CAD and other 3D-software, so it's not just a "gaming" thing. Linux is simply generally more efficient than Windows, at mostly any task.

Valve has done a lot to help improve game performance on Linux, and these improvements are merged into the respective main projects, like kernel and drivers and graphics libraries. The same is simply not possible in Windows, because Windows is proprietary.

Windows used to have a clear advantage in that all optimizations by GPU vendors and game developers were made primarily for Windows and Linux was just an afterthought. Also games were made for DirectX which is native for Windows, and a compatibility layer for Linux.
So for decades games made for both generally ran better on Windows.

So it is absolutely impressive that Linux can now run games faster than Windows. Despite having only a fraction the marketshare.

Cry more :)

Never mind. You people are children.

Says the tantrum thrower? Taking your ball and going home kinda shows the reverse here.
