this would be good enough to compare different mice.Originally Posted by Microx256
If you happen to have a camera capable of high framerates, you can record a short video where there is your mouse and your screen visible, then do a sharp knock on the mouse to move it, and then do the same thing with the other mouse, and then compare the video frame-by-frame to see the difference in which the image on the screen starts changing as opposed to the moment of the mouse moving. This obviously wont tell you the real input lag, but lets you compare two mouses to see fi there is a significant difference.

Just to point out something.
Input lag on a 125hz mouse is 8ms. Then there is a certain delay between the switch being pressed and the that signal being converted to a data signal. That is another 8ms or so (usually less). Total lag is 16 ms.
Now if you take the best mouse on the market you will get 1ms input lag and 1ms signal conversion. Total delay 2 ms.
Great 8 times less. Then we add a human. Which is supposed to use the mouse. And human input lag (or reaction time) is 220-250ms.
So whatever the mouse you have the biggest problem and the biggest lag is you.
Mouse PS/2 is not interrupt based iirc. I think the standard polling rate is only 80 Hz even, can be overclocked to 200 Hz.Originally Posted by Offler
It also depends what you want to measure.
a) Mouse to PC
b) Mouse to Display
First choice is fully within responsibility of mouse manufacturer. Second one is affected by ... everything. Typical mouses are now USB only, but I still prefer PS/2 interface simply because mouse will receive its own interrupt (IRQ) and its not depending on CPU as USB mouses.
This is also why is measurement from blurbusters completely wrong if they wanted to measure Gsync parameters. The method measures difference between clicking the mouse and time when shooting appears on display. There is simply no reason to say that gsync monitor affects something when there is CPU, GPU, memory latency and absolutely everything in the way.
But yes, its true that you can use that method to measure two different mouses, but the results will me very inaccurate.
What you said is utter nonsense. And you completely missed the point.Originally Posted by Axaion

all the more reason to avoid even more "lag", or are you saying youd play the same with a 60hz monitor with 50ms+ gtg time, 60ms input lag, 30 fps ingame and a mouse with another 50ms or so input lag, why not play with 500ms ping while youre at it, i mean, you the human is the -only- limiting factor, right?
Wait, why even 60hz monitor, people can only see 24fps right?, lets build a 24hz monitor to gimp ourselves a bit more![]()

Bigger values matter. Smaller ones dont. 50ms g2g is a big value. And count for up to 20% of the total reaction time. Ofcourse this will harm gameplay.
A 5ms difference is 2%. And this will never have any impact on your performance.
My point is it adds up, and in a multiplayer eviroment if everyone else is equal skill and has 100ms lower delay, they will have a 50% reaction time advantage, which is huge.Originally Posted by the1freeMan

LOL 50ms gtg would require refresh rates broadly under 20Hz ^^
@2shellbonus
Mouse movement is a continuum, not a one time action hence the "feel", the overall perception of movement can change.
Will it give you lower scores in game? Probably not. Can it make playtime more enjoyable? Possibly yes.
Btw I'm about 25% less laggy that your claims![]()
