Re: Interesting project about mouse/ gamepad latency

I don't see how humanbenchmark reaction times are useful anyway. Maybe it's okay for comparing yourself to your past self, but only if you keep the same hardware and software configuration. There are a whole lot of uncontrolled variables that prevent different peoples' scores from being comparable, ...

Re: Interesting project about mouse/ gamepad latency

I have seen (in person) an esports player do ultra-precise mouse movements similar to this: https://twitter.com/slasher/status/1148 ... 09761?s=21 (Just one random impressive example) Though that example is memorization and timing accuracy, not reaction, so you expect a skilled player to be within ...

Re: Interesting project about mouse/ gamepad latency

For visual reaction times with current monitor/mouse input tech, 160 ms average measurements are probably possible, and 140 ms averages are not. I'm not seeing what current tech has to do with it. If you have a latency test program with v-sync off, high framerates, and the whole screen changing col...

Re: Interesting project about mouse/ gamepad latency

IMO, it's inexcusable for a mouse to have average latency over 1ms. MAYBE if you're talking about a $10 mouse, but nothing so expensive you expect a competent engineer to have designed it.

Re: Interesting project about mouse/ gamepad latency

I suggested 200g because it should be enough mass to press the button of most input devices with just its weight. 100g wouldn't be. Dropping it from 5cm above the button should give it enough speed to cross a 1mm actuation distance in about 1ms. Though that is a lot more energy and momentum than you...

Re: Interesting project about mouse/ gamepad latency

We tried something like this using a force sensor. With clicky buttons one could easily determine when the button snapped through because the force applied to the button would suddenly be reduced. But with mushy buttons (many keyboards, gamepads - everything with rubber dome switches), you won't ge...

Re: Interesting project about mouse/ gamepad latency

Always good to have more attention on input lag. Glad to see you have a test setup that measures absolute input lag, rather than just a relative measurement between two mice, which is currently the most popular method for this measurement. 1. the user first touches the input device, 2. the user over...

Re: High refresh rate 1080 CRT monitor

I think 5k is a very low estimate, even if we're talking about today's money. Maybe if we're talking about a small monochromatic tube, but recreating large, high quality, color monitors would have enormous engineering and tooling costs. Hell, you'd probably need to have a foundry custom blend the al...

Re: Perceivable input lag of 10ms and below

It also depends on the absolute input lag, 2 vs 4 ms might be easily noticeable, but 50 vs 52 definitely wouldn't be. This is a big problem, because it means you can't trust feel based AB tests, unless you also measure the absolute latency.
