This might sound silly, but for video games, I’d rather have 800p at 60fps than 4K at 30fps.

Once you get used to 60fps and higher, 30fps drives you up the wall. You’d think it wouldn’t matter since movies typically run at 24fps, but it really matters with video games where reaction time is so important.

@atomicpoet Human reaction time to visual stimuli is ~250ms. In 24fps, one frame is 41ms; at 60fps, one frame is 17fps.

So the maximum delay in seeing an event between these two speeds is 24ms, or about 1/10 of human reaction speed.

Many musicians can perceive time errors down below that level, though...

@TomSwirly There is a big gap in detail between 24fps and 60fps, and if you don’t believe me, try Counter-Strike at both framerates. You will die far more when running at 24fps.

@atomicpoet Alas, in order to save my hands, and my spare time, I long ago gave up addictive games which make heavy use of my manual dexterity!

Go is the only game I play online these days; I do play fairly fast, but not at the speed where milliseconds make a difference.

A 24ms delay would be noticeable when playing music, though you'd compensate (the delay between actuating a note and hearing it can be far greater than that): it doesn't seem unreasonable that it'd affect game play.

@TomSwirly This video by Nvidia does a good job of explaining things.

The refresh rate of a flat panel display is not necessarily in lockstep with the output (frames) of a GPU. There will be gaps between what the GPU renders and the display shows. The lower the FPS, the higher likelihood you’ll see artefacts and ghosting—often resulting in tearing.

And I have experienced tearing on more than one occasion when at lower framerates. It is very distracting.
