What is VFR anyway?

[murlakatamenka]

It's just left as abbreviation but isn't mentioned elsewhere (or is it?)

hyprland-wiki/pages/Configuring/Variables.md

Line 235 in 0d2dee3

| vfr | controls the VFR status of hyprland. Heavily recommended to leave on true to conserve resources. | bool | true |

It has something to do with damage tracking. V Full Redraw or something?

VRR (Variable Refresh Rate aka Adaptive Sync) is more common and thus easier to find, I knew that one.

It has nothing to do with damage tracking.

VFR: New frame is submitted to the pipeline when there is a need for one (something changed and we need to redraw)
No VFR: New frames are submitted every time your monitor has a vblank. This does not mean we redraw everything, if there's nothing to redraw, we'll submit the last drawn frame. This has a serious effect on the CPU usage, though, as the "submitting" takes a bit of CPU.

Okay, thanks for the explanation.

Still, to which human words does it decipher?
