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.

There's a back buffer run by the CPU where it can render another frame in the background and pass it to the GPU so it doesn't have to wait for the primary buffer every time, giving higher frame rates, and also makes odd frame rates work better so you aren't restricted to just 30/60 etc. Reduces tearing, but might introduce input lag where you're dragging a window but the cursor doesn't follow the drag.
Thanks. For normal desktop usage this sounds great (for games the input lag might be bad but that depends on whether there's always input lag and how much), I'm curious what it'll be like in practice.
