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.

Do you know what happens when games run above your refresh rate? Is VRR still engaged there or does it fall back to Wayland's FIFO Vsync?
Afaik, it will fall back to FIFO. Fortunately, if you're using a high refresh rate monitor, by the time you reach this point, FIFO will be adding a very small amount of latency. I generally choose to limit my games to my refresh rate when making use of VRR, as it leads to a good combination of low and consistent latency, rather than the spikes you will face when playing with it unlocked.
