From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

not my words. It's the Valve dev who said it.
I don't think his statement is true though. If https://www.reddit.com/r/linux_gaming/comments/1ce7z19/gaming_on_linux_ep131_ntsync_vs_fsync_nobara_39/l1ho8od/ is not manipulated in any way, games with lots of these calls still get big improvements with ntsync over fsync (about 30% in this particular case, which is a massive boost). So while nobody can rule out that his statement may be true on average or in general, there are still cases where ntsync offers a tangible advantage – be it improved FPS or the fact that the game runs at all.
Edit: in the video that the thread is about, fsync didn't beat ntsync in a single one (or I missed it when jumping through it). In the best one, they were exactly tied. Sure, the difference wasn't really big, but again there are titles not working with fsync.
However, I want to stress that I'm not trying to talk about fsync. It's a good solution that significantly improved performance. But ntsync is, from everything I've seen, almost always better; how much depends on the case, and it never seems to be worse.
Why is he using the term "SteamOS kernel"?
Well, he's talking about the kernel they are using in SteamOS. The Deck OS is also being extended to other handhelds.
Still a weird way to say this.
Not sure there's a better way to say it. I guess "the SteamOS fork of the Linux kernel" would be more explicit, but I assume most people who would read this are aware that SteamOS is built on Linux.
