• It’s mainly for games of course.

    It’s also good for video, as it can play videos at the highest possible Hz multiple of the video’s FPS. So for example 24 FPS video could be played back with 144 Hz, 25 FPS with 125 Hz etc. VRR isn’t technically required for this as many non-VRR monitors support different video modes with different fixed Hz as well, but the transition between Hz is seamless (no need to change video mode).

      • It’s not redrawing the frame, it’s more related to aligning the monitors refresh rate to the frame rate of the content being displayed. Alignment means your monitor doesn’t refresh the screen when the frame is only partially rendered (aka screen tearing).

          • Sure could be, but with most VRR displays the VRR range starts at around 48 Hz, so 24 FPS content would play at least at 48 Hz for example.

            The lowest multiple is likely what’s being used though (I’d have to check), so the numbers in my previous comment are probably off.
