Eli5 : what is vrr ‘ variable refresh rate’ and why is it useful?
In: 17
There’s a whole Wikipedia article on it.
Basically, before displays were only fixed frame rates, say 30Hz. For a 60Hz display, it would just double the 30Hz, but it couldn’t properly play 45Hz.
Modern video games can be rendered basically at whatever the max the computer can handle. More intensive scenes lower the frame rate. A variable refresh rate is what it sounds like, it varies the refresh rate so that the computer isn’t trying to refresh when the frames haven’t been loaded yet, so it drops down from say 120Hz to 100Hz.
