Q & A
What was the main purpose of the video?
-The main purpose of the video was to test and demonstrate the latency differences between wired and wireless gaming mice, as well as to investigate the impact of various factors such as DPI settings and mouse movement speed on sensor latency.
What did the video creator build to measure mouse sensor latency?
-The video creator built a belt-driven machine that can independently control a gaming mouse and trigger NVIDIA's LDAR (Latency Detection and Reporting) software to measure mouse sensor latency.
How does the testing rig work?
-The testing rig works by using an Arduino to trigger a stepper motor and a speaker simultaneously. The speaker emits a beep that triggers the LDAR software, and the stepper motor moves the mouse. The LDAR software detects mouse movement and flashes the screen to record the delay between the movement and its display.
What is the significance of the standard deviation in the test results?
-The standard deviation in the test results indicates the consistency of the latency measurements. A smaller standard deviation, like the one observed in the video, suggests that the test rig is reliable and produces consistent results.
What is DPI in the context of gaming mice?
-DPI, or dots per inch, refers to the resolution of the mouse sensor, which determines the amount of information the sensor can read per inch of movement. Higher DPI settings provide more samples and potentially lower latency.
How did the video creator test the impact of DPI on sensor latency?
-The video creator tested different DPI settings on a gaming mouse while using the testing rig. The results showed that higher DPI settings generally resulted in lower sensor latency and smaller standard deviations.
What is the relationship between mouse movement speed and DPI settings?
-When the mouse movement speed is slower, such as when using wrist movement to track an enemy, higher DPI settings can be more beneficial for reducing latency because there is less information for the sensor to collect.
Did the video creator find a significant difference in sensor latency between different wireless gaming mice?
-Surprisingly, the sensor latency difference between different wireless gaming mice was not significant, with most being within a similar range, despite differences in sensors, firmware, and battery life.
What was the conclusion about the impact of being wired on sensor latency?

Transcripts
so a while ago i made a video showing
that the quick latency difference
between wide and wireless gaming mice
was basically nothing to consider there
was no correlation showing that wireless
gaming mice was slower than wired as
some people still believe today and
really more than anything it's the
d-bounce delay of the mouse that has the
biggest impact on quick latency more
than anything so for those that were
currently using or considering upgrading
to a wireless gaming mouse this was
basically proof that wireless technology
wasn't going to hold you back but
there's one thing missing from that
testing and it's when it comes to the
sensor and with a lot of gaming mice
becoming wireless and a lot of new
brands coming to the market you have to
wonder if all sensors and firmware are
made equally are all modern sensors
actually the same are they all good
enough and what does that mean when it
comes to sensor latency well to start
answering at least a few of these
questions i built this it's a belt
driven machine which can independently
control a gaming mouse and at the same
time trigger nvidia's ldap software so
that we can measure mouse sensor latency
so let's take it through a bit of a test
run today with some different gaming
mics and some different settings and
without spoiling anything yeah there are
some very interesting results
[Music]
so first of all let me explain how all
of this works basically using an arduino
and a few lines of code both a stepper
motor and a speaker are triggered at the
exact same time the speaker emits a loud
beep which triggers the ldap software
and the stepper motor moves the mouse
these two separate instructions are
executed only 150 micro seconds apart so
they're happening pretty much at the
same time once the ldap software hears
the beep from the speaker it then waits
for mouse movement at which point it
detects that and it'll flash the screen
once the screen flashes we get our
result which is the delay between the
mouse movement and the movement being
displayed on the screen i will also
mention that the movement of the mouse
is completely automated with no human
input whatsoever it basically just
repeats the same move over and over
again for a total sample count of 50. so
of course before we actually go ahead
and test anything and compare different
gaming mice in different settings we
need to first see if this thing actually
works in the first place and well yes it
actually works really well admittedly a
lot better than i expected so here's the
same gaming mouse the logitech g pro
super light taken through the same test
five different times and between each
test it was removed and then reinstalled
back into the test rig and the results
here are incredibly close what's even
cooler to see is the incredibly small
standard deviation for each individual
test run illustrated by the orange line
here which is about 1.4 milliseconds for
each test here over 50 samples all right
so the test rig works everything is good
to go and the first thing that i wanted
to test here was whether or not higher
dpi would result in lower sensor latency
dpi is essentially the set resolution of
the sensor the amount of dots per inch
that the sensor is reading so we'd
assume that with higher dpi and more
samples that information can be read
sooner and that results in lower latency
and yeah that's pretty much exactly what
we see not only does sensor latency
decrease as we increase mouse dpi but
the standard deviation also shrinks a
noticeable amount as well with the mouse
sensor set to just 100 dpi we're getting
mouse movement registering on the screen
at 25.7 milliseconds on average but with
some readings above 30 milliseconds now
i don't know anyone who plays on 100 dpi
most people play on either 400 or 800
and there there's about a two to 2.5
millisecond difference in sensor latency
the latency benefits then trail off the
higher that you raise dpi 1600 gives us
a further 1.7 millisecond improvement
over 800 dpi but 3200 dpi only gives us
about a half millisecond improvement on
average so while it's pretty cool for me
to measure and be able to show you these
differences it's not enough for me to
convince you to bump up your mouse dpi
however another factor at play here is
the actual movement speed of the mouse
the results that you've seen so far have
been with the mouse moving at a pretty
typical movement speed if you play on a
low or moderate sensitivity or from
another perspective if you're flicking
to an angle or different target in game
but what about if you're moving your
mouse less for example using only wrist
movement to track an enemy at a moderate
or long distance with less mouse
movement there's less information for
the mouse sensor to collect and so
potentially higher dpi might be more
useful here luckily we can test this
just by simply changing the speed of the
motor and just as we expected the
differences in the results do grow with
the higher dpi setting showing more
beneficial for reducing latency when you
have slower mouse movement now again
obviously no one is going to play on 100
dpi but it's pretty crazy to see the
insane sensor latency that this results
in over 50 milliseconds from end to end
interestingly though the dpi settings
that players are using 400 800 and 1600
there is a measurable decrease in sensor
latency about six milliseconds going
from 400 to 800 dpi and then a further
three milliseconds by bumping up to 1600
so what we can conclude from this
testing is that if you play on a higher
sensitivity it's more beneficial for you
to get that higher sensitivity from your
dpi as opposed to just cranking up the
sensitivity multiplier in game for
example if you play on 400 dpi 1.0 cents
in valorem you'd be better off playing
at 0.5 at 800 dpi or maybe 0.25 at 1600
dpi effectively the feel and sensitivity
will be identical but you'll have lower
sensor lag and higher sensor resolution
at those higher dpi settings and i think
even for low to moderate sensitivity
players this can still be beneficial
when it comes to micro adjustments
tracking and anything that involves fine
mouse control the next thing that i
wanted to test was whether plugging in
the g pro super light would somehow
improve or change the latency result
just out of curiosity and nope the
result is pretty much exactly the same
nothing really worth noting or wasting
time on here next up though let's
compare a bunch of different wireless
gaming mice different sensors different
firmware different battery life and
battery saving techniques but the sensor
latency difference between them is
surprisingly similar at most there's a
3.5 millisecond latency difference
between the g pro super light and the
pwnage ultra custom honestly i was
expecting some bigger differences to
talk about here but it looks like
they're all within pretty much the same
range but lastly what about wired gaming
mice here there's no need to consider
any battery saving techniques or sleep
modes you can just continuously sample
the sensor at full capacity at 1 000
hertz polling rate but does that
actually make a difference well actually
kind of i'll highlight the wired gaming
mics here for reference in white and
yeah they do trend towards the top of
the stack when it comes to sensor lag
granted it's only by two to three
milliseconds on average and again we are
measuring the entire latency chain here
which includes the pc and the display
but it's still really really interesting
to see the only wide mouse that sits
towards the bottom here is the final
mouse ultra light 2 and that's because
that mouse has a max polling rate of 500
hertz whereas the other mice are set to
1 000 hertz so yeah some pretty
interesting results for sure that in the
end the difference here from top to
bottom is only 5 milliseconds that's not
a perceivable difference or one that
will help you win most gunfights but it
does highlight that there are measurable
differences here for whatever reason
that is still though when we're
comparing wide and wireless here for a
mere two millisecond increase in sensor
lag in return for a completely wireless
tether free connection that's a
trade-off that most people should make
especially if you play on a lower
sensitivity wireless is significantly
more comfortable to play with than
slapping around a cable on your desk
you'll probably make better plays in
return and your accuracy will probably
be a little bit better as well than any
2 millisecond latency reduction can give
you at the very least i'm really glad
that i built this tool at least to
validate new models or brands of gaming
mice on the market especially the
wireless gaming mice era that we're all
trending towards no doubt we will see
some different wireless implementations
and sensor sampling techniques in the
future and you can bet more gaming mice
will be put to the test the next step
for the tool will be to evolve it to
test things like mouse acceleration
sensor accuracy micro tracking and
things like that i will need to 3d print
some more upgrades and write some new
testing which will take a couple weeks
but i'm really excited to push that
testing further and further and don't
worry mouse reviews will still focus
heavily on shape and build quality and
all of that important stuff as well but
i think that you know sensor latency and
quick latency tests are really important
too moving forward
until then a huge thanks for watching
and i will see you all in the next one
