Just had a flick over the code and it appears to be trying to test exactly what I'm interested in, did anyone get to use this code ? was any measurements made ?

Yep: viewtopic.php?f=10&t=5327

I should be able to code this being a full time developer, I just need the hardware and the time

Here's a related project, should save you some time: https://github.com/PDA-UR/LagBox

The best way to check your keyboard's scan rate is to measure the scan rate with an oscillocope, frequency counter, logic analyzer, some multimeters, etc. That site you linked to is worthless. It listed a keyboard with a 1.5ms matrix scan interval at 20ms. latency is harder to test, you can only com...

Could be placebo, could be real. Only way to find out which is true is to actually measure the performance on your specific system.

With v-sync off you shouldn't be getting any input latency due to refresh rate, because you're not waiting for the next refresh to display the new frame. You will get latency due to framerate though. 240hz camera is also a little slow for this. 8 to 14ms is pretty good if we're talking about an actu...

Depends on what you're measuring, because the whole screen doesn't update at the same instant. V-sync on vs off, or a single point on the screen vs anywhere on the screen. You won't see that 4.16ms if you're talking about vsync off and are looking for a change anywhere on the screen. You will see it...

Not sure what you mean by "real". Yes, CRTs can have high refresh rates, it comes with reduced resolution. Whether this tradeoff is worth it or not depends on you. Most people with CRTs use neither the highest supported resolution nor the highest supported refresh rate, but choose something in betw...

Most people with CRTs use neither the highest supported resolution nor the highest supported refresh rate, but choose something in between

I wrote up my version of it here: https://forums.blurbusters.com/viewtopic.php?f=10&t=3005&p=22634#p22634 Though the code will only work for the boards with native USB, like the micro or leonardo. I don't think the mega can enumerate as a mouse. You can replace R1 and R3 with a phototransistor and a...

In theory, it shouldn't matter, but that 30fps cap might not actually be exactly 30fps, so you can get the 33ms of animation happening in 16.7ms of on-monitor time, and then the next frame you have 33ms of animation happening in 50ms. That's assuming v-sync on. With v-sync off, it gets more complica...
