it is a hot day and you know what's refreshing on a
hot day these guys aren't a sponsor no today what we're gonna be doing is we're
going to be taking gsync so this is the Green Team over here this green graphics
card and that black monitor with a red lighter okay don't worry too much about
it that's the Green Team over there and then on the red team we have the R9 Fury
X which is actually inside this computer right now and the BenQ XL 2730
Z so I would consider that and the Rog Swift pg278 Q pretty much equivalent as
far as a gsync versus a freesync monitor goes so we're going to be doing
something pretty interesting we're going to be taking a look at which g-sync or
freesync both with 144hz displays offers
the lowest input leg so the least
latency between pressing the mouse and
firing the gun stay tuned
vote for turnup it's a shirt I don't have one so we're going to do our best
to demo what it looks like and this is not what the real shirt looks like it
looks a little more like this but we didn't have a sample to show you guys so
this had to do uh you can stay tuned after the outro for bonus footage of the
creation of this masterpiece if you're into that sort of thing so the first
thing I'll need to do is uh oh yeah guys this just arrived today drop a like on
the video if you want to see the uh 3dr
solo taken for a test drive we've actually got some pretty good ideas
burkel who just about killed himself recently on his mountain bike wants to
test the follow feature on his bike so drop a dislike if you think that that's
a terrible idea and we should actually go ahead and just review it
normally so the first thing we're going to need is on my desk over here now one
of the better uh methodologies that I
found online and I love those guys over at blur Busters they make my job so much
easier uh one of the better methodologies I found online is to have
an LED that illuminates on an input to
the computer so in this case we're going to be using the Makey Makey which has
indicator LEDs on board and then we're just going to go ahead and we're going
to do a mouse click that's going to light up and then we're going to be able
to see how many milliseconds it takes with a high-speed camera before our
muzzle flare or Flash whatever the bullet comes out
of the gun so here we go let's head downstairs and get our monitors together
I like these Vlog Style videos because this is basically what's happening with
every one of our videos except uh with this style you guys get to kind of come
along for the ride as we go on Voyages of Discovery in The Labyrinth that is
the LMG headquarters to find the hardware that we need in order to make
whatever stupid video it is we're trying to make that that day so are you
standing on a oh dear I am only half standing on a
rotating sphere disc machine ball at
least it doesn't have wheel oh at least this isn't
heavy it's actually fairly heavy okay here we go want no I got this don't turn
don't don't turn don't turn okay and
down never do
that why did I packed this monitor up I knew I wanted to do this
comparison all of what we do is nothing without
editing Okay so we've got both monitors
here all right
competitors
lovers no one is sure what I'm talking about are you no that's okay that's fine
that's normal everything is fine for
some reason it started working and I don't know why and I'm not going to question it
okay yes I
victorious yes yes okay so what made the mouse
work no devices
detected what do you mean no devices
detected okay so now that my stupid piece of crap Windows 7 install has
completely itself and won't work with a
keyboard or Mouse which I'm going to diagnose later with my handy dandy PS2
keyboard and mouse uh can install a USB
keyboard or Mouse trust me we've tried um we're going we've gone ahead and
switched to my Windows 8 test drive and it is time to get the Makey Makey up and
running first of all so we've uh We've set it up for click and ground and then
we're going to position this so we can see the activity LED Boop look at that
we clicked well hold on hold on well I got
to put it somewhere useful okay ready so you can watch the
LED illuminate just like that see that
okay so that led is going to be the indicator
of when the gunfire should start in
Crisis 3 now the reason we're using Crisis 3 is that blur Busters has
already done the groundwork for us those guys are awesome which I think I already
said once but it deserves being said again and have found that Crisis 3 uses
a particularly not leggy engine not as
much as csgo mind you but CS go requires some fiddling around with uh Max FPS
settings within the console that we're just not going to do here so we've got
our Fury X on the bench I've got the latest drivers that just finished
downloading we're going to go ahead and install those and boom we're going to find out how
much latency between click and display
with free sync enabled all right so the first thing
we're going to need to do is enable free sync now this is not quite as cut and
dried as it used to be with gsync because you can also enable or disable
vsync From Within game so we're actually going to have to look at it four
different ways we're going to have 144 Hertz with freesync with vsync on or off
then we're going to do gsync with the same thing with vsync on or off and then
have a look at how things go okay so
we're in our game um we're going to Target 200 FPS for our uncapped scenario
and then basically all we're going to do is we're going
to fire the mouse or well fire the mouse
uh fire the gun like that now this is our Sony fs700
camera and what it will be doing is recording the screen at 480 frames per
second unless we discover that 480 frames per second is not good enough in
which case we will record at 960 FPS but
the image gets very grainy and very dark at that frame rate so it's a little bit
harder to work with so we're really hoping for the best here so uh let's get
started where where is that damn
remote it's not under the motherboard it's good it shouldn't have been there
here it is so the genius is at Sony which I have clearly demonstrated myself
to be uh uh a more genius than installed
the remote IR sensor for this camera in
the back of it so the talent may never actually use it um you know I don't know
maybe like here and like sticking out so it works from any direction whatever so
I use reflective tape here and then I can be like B bam bounce it and it will
start and stop just like that that way I
will be able to start the slow motion recording which only runs for 4 seconds
I will be able to take some shots not that kind of take shots what kind of
videos you think we make around here and then I will be able to review the
footage and start oh it didn't work and
start here we go 1 2 3 4 5 6 7 8 9 10 11
12 13 14 15 and it's probably done now
okay so let's check it out let's check it out so here we go here we go here we go you can clearly see a delay and this
is running faster than the actual footage will be exciting so let's come
back with some numbers so welcome to the next step in
the process it's actually been it it ended up taking me like 3 hours or
something like that to run all of the numbers that I needed but basically what
it amounts to is I've got my folder full of Clips here so these are all slow
motion clips of here we go so check this
out so you can see these are at 960 frames per second so like the you can
barely you can actually see the individual Blades of the fan spinning
and then what you're going to see here is a significant delay eventually right
here we go here we go between the
light and the actual muzzle flash so
that's not good enough what we need to do is take this footage and dump it into
Adobe Premiere where we can make an approximate equivalency of one of our
frames is about a millisecond and then what we do is we actually find the exact
frame where the top LED begins to illuminate and then we count 1 2 3 4 5 6
7 8 9 10 11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30 31 32
there we go and then when we see the first hint of the muzzle flash animation
that's when I make my mark That's when I put down my result and we're already
getting some really interesting results which is turning the into more like a a
regular lineus Tech tips at this point not very vloggy with like graphs and
everything but sometimes I'm just not in control of what video I end up making I
set out to do one thing and then it's like all of a sudden I'm making videos
about Subway sandwich napkins in the way that you could actually use one to
replace the built-in eraser on your dry erase marker if it was too full of crap
with just a pair of scissors and a doublea battery to help you also some
tape ah yes a
knife it's covered in peanut butter oh my God why am I sitting at taran's
desk so I'm not sure if it's because they think it improves their job
security but my editors let me sit here for an hour counting frames one
by one instead of just showing me this super easy way to do it by changing this
to frames and then just marking in and
out and then getting a frame count right here so that's a faster way to do that
little do they know that that does not improve job security oh we just told you
I'm going to replace them all with robots these These are the
future video editing like that so I feel
a bit like every Linus Tech tips video is sort of like um like life you know
you start out with joy and hope and
belief that the world makes sense and then by the end of it you're this jaded
bitter soul that just what the hell is going on here
so all right I'll I'll put all the results up on screen for you guys or
more accurately I'll have an editor do it since as you obviously know I don't
know how to use Adobe Premiere so um at high frame rate so at 144 Hertz 144 FPS
remember we're using gsync or freesync regardless of what else is going on with
vsync or no vsync so with no vsync um
dsync really does okay but freesync
actually comes out ahead at 1440p with the xl2730z looking like it's overall a
lower input leg chain along with the R9
Fury X so with vsync however so this is
g-sync with vsync the way NVIDIA intended for it to be used before they
eventually caved and allowed vsync to be turned off now we see gsync really come
into its own with not only really really
low latency between LED light illumination and muzzle flash but also a
really tight grouping of the of the latency here with free sync being a
little bit sloppier now when we move up to 200 FPS you can see that no vsync
doesn't actually give us on gsync an
input leg reduction whereas with AMD
free sync now that we have desynchronized we are actually getting a
proportional improvement in our input leg this is what we expect but this this
is where my brain explodes at 45 FPS
remember this is the sweet spot for variable refresh rate gaming with bsync
disabled NVIDIA just cleans up cleans
house we're talking 72 to 73 frames with
our camera that is outstanding at only 45 FPS that is an incredible delay with
freesync not only much higher but also a
little bit all over the place in terms of the latency then we turned vsync on
and I just retested this to make sure I wasn't crazy if we turn vsync on forcing
it through the driver or turning it on in game I just retested
it gsync is actually as bad or worse
than free sync so ultimately today we have raised
more questions than we have answered uh
what we do know is that at least on AMD
free sync you are going to if you're
going to exceed the maximum refresh rate of your monitor then you are probably
going to want to go ahead and disable vsync if you want that 10 millisecond
Improvement in input latency so like the
responsiveness and on g-sync if you're going to be playing in that 45 FPS sweet
spot where I guess NVIDIA intended for it to be used then you are going to want
vsync off for some reason but then if
you're going to be playing at a much higher refresh rate it looks like vsync
on is the cat's pajamas with g-sync so uh
let us know in the comments if your interpretation here is uh is different
than my own and uh thank you for tuning in to this little Adventure I'm just
going to look at my calendar and it looks like I'm supposed to tell you
about Mast drop but I have no idea what their featured product is so I'll film
that at a later time so thanks for watching guys like the or no I have a
new outro dislike the video If You disliked it you guys know how to do that
like it if you did like it though also get subscribed and maybe even consider
contributing to us whether it's directly through our Forum by buying a t-shirt or
by shopping at Amazon with our affiliate code once you've done all that stuff and
you're looking for something new to watch uh apparently we just released ah
yes we just released our Fury X versus 980ti small form factor you know Uber
gaming machine Showdown so check that out and guess we're done here
