VRRTest

A very small utility I wrote to test variable refresh rate on Linux. Should work on all major OSes.

Usage

Just run the executable. Builds are provided for Windows and Linux (64-bit). You can download the LÖVE [https://love2d.org] runtime to run the .love file on any supported OS on any supported architecture.
Assuming the runtime is installed and in PATH, you can run it with love <dir>, where <dir> is the directory where this repo is cloned/extracted.

• Up and down arrows will change the target FPS of the tool.
• Left and right arrows will change the amount of columns the screen is divided into.
• The f key toggles fullscreen.
• The b key toggles busy waiting. Having it on makes the framerate more precise, at the cost of a ton of battery and CPU utilization. Off by default.

I don't know why'd you want any. Still, here's one.
