1
00:00:00,120 --> 00:00:06,480
it is a hot day and you know what's refreshing on a

2
00:00:03,959 --> 00:00:11,360
hot day these guys aren't a sponsor no today what we're gonna be doing is we're

3
00:00:08,800 --> 00:00:17,400
going to be taking gsync so this is the Green Team over here this green graphics

4
00:00:14,599 --> 00:00:20,519
card and that black monitor with a red lighter okay don't worry too much about

5
00:00:18,680 --> 00:00:25,760
it that's the Green Team over there and then on the red team we have the R9 Fury

6
00:00:23,480 --> 00:00:32,239
X which is actually inside this computer right now and the BenQ XL 2730

7
00:00:30,160 --> 00:00:38,200
Z so I would consider that and the Rog Swift pg278 Q pretty much equivalent as

8
00:00:35,960 --> 00:00:41,320
far as a gsync versus a freesync monitor goes so we're going to be doing

9
00:00:40,200 --> 00:00:47,600
something pretty interesting we're going to be taking a look at which g-sync or

10
00:00:43,680 --> 00:00:50,680
freesync both with 144hz displays offers

11
00:00:47,600 --> 00:00:53,960
the lowest input leg so the least

12
00:00:50,680 --> 00:00:58,240
latency between pressing the mouse and

13
00:00:53,960 --> 00:01:06,640
firing the gun stay tuned

14
00:01:06,640 --> 00:01:12,680
vote for turnup it's a shirt I don't have one so we're going to do our best

15
00:01:10,720 --> 00:01:15,799
to demo what it looks like and this is not what the real shirt looks like it

16
00:01:14,360 --> 00:01:20,240
looks a little more like this but we didn't have a sample to show you guys so

17
00:01:17,759 --> 00:01:24,240
this had to do uh you can stay tuned after the outro for bonus footage of the

18
00:01:22,200 --> 00:01:29,240
creation of this masterpiece if you're into that sort of thing so the first

19
00:01:26,400 --> 00:01:35,000
thing I'll need to do is uh oh yeah guys this just arrived today drop a like on

20
00:01:31,560 --> 00:01:37,479
the video if you want to see the uh 3dr

21
00:01:35,000 --> 00:01:41,240
solo taken for a test drive we've actually got some pretty good ideas

22
00:01:38,680 --> 00:01:45,600
burkel who just about killed himself recently on his mountain bike wants to

23
00:01:43,399 --> 00:01:49,680
test the follow feature on his bike so drop a dislike if you think that that's

24
00:01:47,520 --> 00:01:53,680
a terrible idea and we should actually go ahead and just review it

25
00:01:51,759 --> 00:01:59,600
normally so the first thing we're going to need is on my desk over here now one

26
00:01:56,600 --> 00:02:01,560
of the better uh methodologies that I

27
00:01:59,600 --> 00:02:04,799
found online and I love those guys over at blur Busters they make my job so much

28
00:02:03,360 --> 00:02:11,599
easier uh one of the better methodologies I found online is to have

29
00:02:07,399 --> 00:02:13,599
an LED that illuminates on an input to

30
00:02:11,599 --> 00:02:17,800
the computer so in this case we're going to be using the Makey Makey which has

31
00:02:15,400 --> 00:02:20,599
indicator LEDs on board and then we're just going to go ahead and we're going

32
00:02:18,840 --> 00:02:25,120
to do a mouse click that's going to light up and then we're going to be able

33
00:02:22,160 --> 00:02:30,400
to see how many milliseconds it takes with a high-speed camera before our

34
00:02:28,319 --> 00:02:35,239
muzzle flare or Flash whatever the bullet comes out

35
00:02:33,000 --> 00:02:39,800
of the gun so here we go let's head downstairs and get our monitors together

36
00:02:37,080 --> 00:02:44,560
I like these Vlog Style videos because this is basically what's happening with

37
00:02:41,800 --> 00:02:49,480
every one of our videos except uh with this style you guys get to kind of come

38
00:02:46,640 --> 00:02:55,239
along for the ride as we go on Voyages of Discovery in The Labyrinth that is

39
00:02:52,760 --> 00:02:59,400
the LMG headquarters to find the hardware that we need in order to make

40
00:02:57,680 --> 00:03:04,040
whatever stupid video it is we're trying to make that that day so are you

41
00:03:01,640 --> 00:03:09,360
standing on a oh dear I am only half standing on a

42
00:03:05,840 --> 00:03:11,239
rotating sphere disc machine ball at

43
00:03:09,360 --> 00:03:15,560
least it doesn't have wheel oh at least this isn't

44
00:03:12,599 --> 00:03:22,920
heavy it's actually fairly heavy okay here we go want no I got this don't turn

45
00:03:18,760 --> 00:03:25,799
don't don't turn don't turn okay and

46
00:03:22,920 --> 00:03:25,799
down never do

47
00:03:28,400 --> 00:03:34,560
that why did I packed this monitor up I knew I wanted to do this

48
00:03:36,040 --> 00:03:40,680
comparison all of what we do is nothing without

49
00:03:44,519 --> 00:03:51,159
editing Okay so we've got both monitors

50
00:03:51,680 --> 00:03:58,079
here all right

51
00:03:55,079 --> 00:03:58,079
competitors

52
00:03:58,200 --> 00:04:07,840
lovers no one is sure what I'm talking about are you no that's okay that's fine

53
00:04:04,480 --> 00:04:09,280
that's normal everything is fine for

54
00:04:07,840 --> 00:04:13,720
some reason it started working and I don't know why and I'm not going to question it

55
00:04:11,879 --> 00:04:18,919
okay yes I

56
00:04:16,479 --> 00:04:26,479
victorious yes yes okay so what made the mouse

57
00:04:23,360 --> 00:04:28,240
work no devices

58
00:04:26,479 --> 00:04:34,560
detected what do you mean no devices

59
00:04:32,039 --> 00:04:42,160
detected okay so now that my stupid piece of crap Windows 7 install has

60
00:04:38,800 --> 00:04:44,240
completely itself and won't work with a

61
00:04:42,160 --> 00:04:50,600
keyboard or Mouse which I'm going to diagnose later with my handy dandy PS2

62
00:04:47,360 --> 00:04:52,639
keyboard and mouse uh can install a USB

63
00:04:50,600 --> 00:04:56,560
keyboard or Mouse trust me we've tried um we're going we've gone ahead and

64
00:04:54,240 --> 00:05:00,840
switched to my Windows 8 test drive and it is time to get the Makey Makey up and

65
00:04:58,479 --> 00:05:06,919
running first of all so we've uh We've set it up for click and ground and then

66
00:05:04,080 --> 00:05:12,080
we're going to position this so we can see the activity LED Boop look at that

67
00:05:10,919 --> 00:05:16,479
we clicked well hold on hold on well I got

68
00:05:14,120 --> 00:05:21,039
to put it somewhere useful okay ready so you can watch the

69
00:05:17,759 --> 00:05:23,840
LED illuminate just like that see that

70
00:05:21,039 --> 00:05:29,840
okay so that led is going to be the indicator

71
00:05:25,759 --> 00:05:31,319
of when the gunfire should start in

72
00:05:29,840 --> 00:05:35,160
Crisis 3 now the reason we're using Crisis 3 is that blur Busters has

73
00:05:33,120 --> 00:05:38,280
already done the groundwork for us those guys are awesome which I think I already

74
00:05:36,560 --> 00:05:43,880
said once but it deserves being said again and have found that Crisis 3 uses

75
00:05:40,720 --> 00:05:46,560
a particularly not leggy engine not as

76
00:05:43,880 --> 00:05:51,759
much as csgo mind you but CS go requires some fiddling around with uh Max FPS

77
00:05:49,240 --> 00:05:55,880
settings within the console that we're just not going to do here so we've got

78
00:05:53,960 --> 00:05:59,199
our Fury X on the bench I've got the latest drivers that just finished

79
00:05:58,039 --> 00:06:06,400
downloading we're going to go ahead and install those and boom we're going to find out how

80
00:06:02,680 --> 00:06:07,759
much latency between click and display

81
00:06:06,400 --> 00:06:11,000
with free sync enabled all right so the first thing

82
00:06:09,560 --> 00:06:15,960
we're going to need to do is enable free sync now this is not quite as cut and

83
00:06:13,319 --> 00:06:20,520
dried as it used to be with gsync because you can also enable or disable

84
00:06:17,960 --> 00:06:24,360
vsync From Within game so we're actually going to have to look at it four

85
00:06:21,919 --> 00:06:29,039
different ways we're going to have 144 Hertz with freesync with vsync on or off

86
00:06:27,479 --> 00:06:35,000
then we're going to do gsync with the same thing with vsync on or off and then

87
00:06:31,759 --> 00:06:37,319
have a look at how things go okay so

88
00:06:35,000 --> 00:06:44,919
we're in our game um we're going to Target 200 FPS for our uncapped scenario

89
00:06:42,440 --> 00:06:49,919
and then basically all we're going to do is we're going

90
00:06:46,639 --> 00:06:52,199
to fire the mouse or well fire the mouse

91
00:06:49,919 --> 00:06:59,599
uh fire the gun like that now this is our Sony fs700

92
00:06:57,400 --> 00:07:04,520
camera and what it will be doing is recording the screen at 480 frames per

93
00:07:02,639 --> 00:07:09,919
second unless we discover that 480 frames per second is not good enough in

94
00:07:06,639 --> 00:07:12,240
which case we will record at 960 FPS but

95
00:07:09,919 --> 00:07:14,879
the image gets very grainy and very dark at that frame rate so it's a little bit

96
00:07:13,639 --> 00:07:23,080
harder to work with so we're really hoping for the best here so uh let's get

97
00:07:19,680 --> 00:07:25,720
started where where is that damn

98
00:07:23,080 --> 00:07:30,520
remote it's not under the motherboard it's good it shouldn't have been there

99
00:07:28,039 --> 00:07:36,400
here it is so the genius is at Sony which I have clearly demonstrated myself

100
00:07:32,639 --> 00:07:39,400
to be uh uh a more genius than installed

101
00:07:36,400 --> 00:07:41,720
the remote IR sensor for this camera in

102
00:07:39,400 --> 00:07:46,520
the back of it so the talent may never actually use it um you know I don't know

103
00:07:44,599 --> 00:07:51,520
maybe like here and like sticking out so it works from any direction whatever so

104
00:07:48,720 --> 00:07:58,400
I use reflective tape here and then I can be like B bam bounce it and it will

105
00:07:55,319 --> 00:08:00,520
start and stop just like that that way I

106
00:07:58,400 --> 00:08:05,639
will be able to start the slow motion recording which only runs for 4 seconds

107
00:08:02,960 --> 00:08:09,639
I will be able to take some shots not that kind of take shots what kind of

108
00:08:07,199 --> 00:08:17,199
videos you think we make around here and then I will be able to review the

109
00:08:12,680 --> 00:08:22,720
footage and start oh it didn't work and

110
00:08:17,199 --> 00:08:25,960
start here we go 1 2 3 4 5 6 7 8 9 10 11

111
00:08:22,720 --> 00:08:27,520
12 13 14 15 and it's probably done now

112
00:08:25,960 --> 00:08:33,640
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

113
00:08:31,919 --> 00:08:37,440
is running faster than the actual footage will be exciting so let's come

114
00:08:36,120 --> 00:08:41,800
back with some numbers so welcome to the next step in

115
00:08:39,839 --> 00:08:46,600
the process it's actually been it it ended up taking me like 3 hours or

116
00:08:44,880 --> 00:08:51,279
something like that to run all of the numbers that I needed but basically what

117
00:08:48,519 --> 00:08:58,200
it amounts to is I've got my folder full of Clips here so these are all slow

118
00:08:54,120 --> 00:09:00,240
motion clips of here we go so check this

119
00:08:58,200 --> 00:09:04,399
out so you can see these are at 960 frames per second so like the you can

120
00:09:02,480 --> 00:09:08,399
barely you can actually see the individual Blades of the fan spinning

121
00:09:06,560 --> 00:09:15,600
and then what you're going to see here is a significant delay eventually right

122
00:09:12,399 --> 00:09:19,440
here we go here we go between the

123
00:09:15,600 --> 00:09:20,920
light and the actual muzzle flash so

124
00:09:19,440 --> 00:09:26,480
that's not good enough what we need to do is take this footage and dump it into

125
00:09:23,880 --> 00:09:31,000
Adobe Premiere where we can make an approximate equivalency of one of our

126
00:09:28,640 --> 00:09:36,880
frames is about a millisecond and then what we do is we actually find the exact

127
00:09:34,560 --> 00:09:42,839
frame where the top LED begins to illuminate and then we count 1 2 3 4 5 6

128
00:09:39,720 --> 00:09:47,360
7 8 9 10 11 12 13 14 15 16 17 18 19 20

129
00:09:42,839 --> 00:09:49,040
21 22 23 24 25 26 27 28 29 30 31 32

130
00:09:47,360 --> 00:09:54,880
there we go and then when we see the first hint of the muzzle flash animation

131
00:09:52,800 --> 00:09:58,640
that's when I make my mark That's when I put down my result and we're already

132
00:09:56,760 --> 00:10:03,000
getting some really interesting results which is turning the into more like a a

133
00:10:01,240 --> 00:10:06,440
regular lineus Tech tips at this point not very vloggy with like graphs and

134
00:10:04,680 --> 00:10:11,160
everything but sometimes I'm just not in control of what video I end up making I

135
00:10:08,920 --> 00:10:15,120
set out to do one thing and then it's like all of a sudden I'm making videos

136
00:10:12,959 --> 00:10:19,480
about Subway sandwich napkins in the way that you could actually use one to

137
00:10:17,240 --> 00:10:24,600
replace the built-in eraser on your dry erase marker if it was too full of crap

138
00:10:22,160 --> 00:10:31,760
with just a pair of scissors and a doublea battery to help you also some

139
00:10:27,720 --> 00:10:31,760
tape ah yes a

140
00:10:32,440 --> 00:10:39,839
knife it's covered in peanut butter oh my God why am I sitting at taran's

141
00:10:37,639 --> 00:10:43,360
desk so I'm not sure if it's because they think it improves their job

142
00:10:41,200 --> 00:10:48,560
security but my editors let me sit here for an hour counting frames one

143
00:10:46,160 --> 00:10:55,560
by one instead of just showing me this super easy way to do it by changing this

144
00:10:51,600 --> 00:10:57,760
to frames and then just marking in and

145
00:10:55,560 --> 00:11:03,200
out and then getting a frame count right here so that's a faster way to do that

146
00:11:00,760 --> 00:11:08,240
little do they know that that does not improve job security oh we just told you

147
00:11:06,320 --> 00:11:12,480
I'm going to replace them all with robots these These are the

148
00:11:12,720 --> 00:11:18,639
future video editing like that so I feel

149
00:11:16,519 --> 00:11:25,120
a bit like every Linus Tech tips video is sort of like um like life you know

150
00:11:21,279 --> 00:11:26,920
you start out with joy and hope and

151
00:11:25,120 --> 00:11:31,639
belief that the world makes sense and then by the end of it you're this jaded

152
00:11:28,880 --> 00:11:35,839
bitter soul that just what the hell is going on here

153
00:11:33,720 --> 00:11:39,720
so all right I'll I'll put all the results up on screen for you guys or

154
00:11:38,079 --> 00:11:44,000
more accurately I'll have an editor do it since as you obviously know I don't

155
00:11:41,240 --> 00:11:50,240
know how to use Adobe Premiere so um at high frame rate so at 144 Hertz 144 FPS

156
00:11:47,680 --> 00:11:58,440
remember we're using gsync or freesync regardless of what else is going on with

157
00:11:52,519 --> 00:12:02,200
vsync or no vsync so with no vsync um

158
00:11:58,440 --> 00:12:04,120
dsync really does okay but freesync

159
00:12:02,200 --> 00:12:11,440
actually comes out ahead at 1440p with the xl2730z looking like it's overall a

160
00:12:07,519 --> 00:12:14,639
lower input leg chain along with the R9

161
00:12:11,440 --> 00:12:16,519
Fury X so with vsync however so this is

162
00:12:14,639 --> 00:12:21,040
g-sync with vsync the way NVIDIA intended for it to be used before they

163
00:12:18,399 --> 00:12:27,639
eventually caved and allowed vsync to be turned off now we see gsync really come

164
00:12:23,839 --> 00:12:29,880
into its own with not only really really

165
00:12:27,639 --> 00:12:35,079
low latency between LED light illumination and muzzle flash but also a

166
00:12:32,519 --> 00:12:38,680
really tight grouping of the of the latency here with free sync being a

167
00:12:36,600 --> 00:12:46,760
little bit sloppier now when we move up to 200 FPS you can see that no vsync

168
00:12:43,000 --> 00:12:50,160
doesn't actually give us on gsync an

169
00:12:46,760 --> 00:12:51,880
input leg reduction whereas with AMD

170
00:12:50,160 --> 00:12:56,519
free sync now that we have desynchronized we are actually getting a

171
00:12:53,920 --> 00:13:03,279
proportional improvement in our input leg this is what we expect but this this

172
00:12:59,600 --> 00:13:05,160
is where my brain explodes at 45 FPS

173
00:13:03,279 --> 00:13:13,560
remember this is the sweet spot for variable refresh rate gaming with bsync

174
00:13:10,279 --> 00:13:16,720
disabled NVIDIA just cleans up cleans

175
00:13:13,560 --> 00:13:19,040
house we're talking 72 to 73 frames with

176
00:13:16,720 --> 00:13:25,199
our camera that is outstanding at only 45 FPS that is an incredible delay with

177
00:13:22,000 --> 00:13:27,480
freesync not only much higher but also a

178
00:13:25,199 --> 00:13:33,079
little bit all over the place in terms of the latency then we turned vsync on

179
00:13:30,320 --> 00:13:38,199
and I just retested this to make sure I wasn't crazy if we turn vsync on forcing

180
00:13:36,279 --> 00:13:45,240
it through the driver or turning it on in game I just retested

181
00:13:40,800 --> 00:13:46,880
it gsync is actually as bad or worse

182
00:13:45,240 --> 00:13:53,959
than free sync so ultimately today we have raised

183
00:13:50,399 --> 00:13:57,079
more questions than we have answered uh

184
00:13:53,959 --> 00:14:00,440
what we do know is that at least on AMD

185
00:13:57,079 --> 00:14:02,399
free sync you are going to if you're

186
00:14:00,440 --> 00:14:05,600
going to exceed the maximum refresh rate of your monitor then you are probably

187
00:14:04,160 --> 00:14:10,759
going to want to go ahead and disable vsync if you want that 10 millisecond

188
00:14:07,720 --> 00:14:13,279
Improvement in input latency so like the

189
00:14:10,759 --> 00:14:17,600
responsiveness and on g-sync if you're going to be playing in that 45 FPS sweet

190
00:14:15,680 --> 00:14:25,079
spot where I guess NVIDIA intended for it to be used then you are going to want

191
00:14:21,279 --> 00:14:26,480
vsync off for some reason but then if

192
00:14:25,079 --> 00:14:29,880
you're going to be playing at a much higher refresh rate it looks like vsync

193
00:14:28,600 --> 00:14:35,880
on is the cat's pajamas with g-sync so uh

194
00:14:34,040 --> 00:14:42,079
let us know in the comments if your interpretation here is uh is different

195
00:14:39,680 --> 00:14:46,279
than my own and uh thank you for tuning in to this little Adventure I'm just

196
00:14:44,279 --> 00:14:49,440
going to look at my calendar and it looks like I'm supposed to tell you

197
00:14:47,519 --> 00:14:53,440
about Mast drop but I have no idea what their featured product is so I'll film

198
00:14:51,240 --> 00:14:57,959
that at a later time so thanks for watching guys like the or no I have a

199
00:14:55,720 --> 00:15:02,360
new outro dislike the video If You disliked it you guys know how to do that

200
00:15:00,519 --> 00:15:06,440
like it if you did like it though also get subscribed and maybe even consider

00:15:08,440 --> 00:15:13,320
by shopping at Amazon with our affiliate code once you've done all that stuff and

203
00:15:12,120 --> 00:15:18,680
you're looking for something new to watch uh apparently we just released ah

204
00:15:16,320 --> 00:15:25,040
yes we just released our Fury X versus 980ti small form factor you know Uber

205
00:15:22,279 --> 00:15:30,120
gaming machine Showdown so check that out and guess we're done here
