===== How to Enable Tearfree Mode (and what is it?) =====

Tearfree is like a triple buffer for graphics. As the name implies, it's great at stopping tearing that's so annoying on my system.

It is NOT freesync, that is separate.

Enable it like this:

  xrandr --output DisplayPort-1 --set TearFree on

Some games might go 5fps, in which case, disable it again, since games usually have their own buffer and vsync.
