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.

Triple Buffering pushed to Gnome 48 (lemmy.world)

Retargeted triple buffering to GNOME 48 instead of trying to upstream it in 47 at the last minute. Actually upstream wants it in 47 more than we do. But recent code reviews are both too numerous to resolve quickly and too destabilizing if implemented fully. So I’m not going to do that so close to release. There are still no known bugs to worry about and the distro patch for 24.10 only needs to be supported until EOL in July 2025.

I heard it creates latency so I hope it will be disabled in games and stuff like that.

Xaver Hugl, one of the KDE devs, wrote a wonderful post explaining triple buffering. Maybe check this out.

TL;DR (In the context of KDE Plasma) With all those changes implemented in Plasma 6.1, triple buffering on Wayland

is only active if KWin predicts rendering to take longer than a refresh cycle
doesn’t add more latency than necessary even while triple buffering is active, at least as long as render time prediction is decent
works independently of what GPU you have

Triple buffering is only active if the GPU isn't keeping up with double buffering. So it will mainly only be active for lower powered devices, like older integrated GPUs.

But in games the GPU technically never keeps up.

but in games, triple buffering is the norm

Yes but usually there's an option to disable it (either in the game settings or in the GPU control panel).
