1
00:00:00,160 --> 00:00:08,080
virtual reality or vr has been hailed as the next paradigm for gaming and

2
00:00:04,960 --> 00:00:10,719
immersion ever since it rolled out then

3
00:00:08,080 --> 00:00:16,320
rolled over back in the late 90s with early implementations like sony's glass

4
00:00:12,960 --> 00:00:20,160
tron being described by john carmack as

5
00:00:16,320 --> 00:00:23,199
like looking through toilet paper tubes

6
00:00:20,160 --> 00:00:25,840
fast forward to 2016 though and the tech

7
00:00:23,199 --> 00:00:30,800
was awesome but it still had a big problem the price

8
00:00:28,080 --> 00:00:35,760
because on top of the headset gamers in particular needed to shell out

9
00:00:33,280 --> 00:00:39,520
for much more powerful hardware than they would need to play the same game in

10
00:00:38,160 --> 00:00:44,480
flat mode but there's some good news

11
00:00:41,840 --> 00:00:48,320
since that time oculus who sponsored this video has dropped the price of the

12
00:00:46,800 --> 00:00:52,960
rift and continued development on some pretty

13
00:00:50,480 --> 00:00:58,160
neat invisible mechanisms that work in the background to make vr run on even

14
00:00:55,520 --> 00:01:03,359
relatively modest machines and we spent the last week testing to see

15
00:01:00,399 --> 00:01:14,799
just how modest a machine you can use and i think you'll be surprised

16
00:01:14,799 --> 00:01:21,280
let's begin with some of the efficiency improvements that are handled by your

17
00:01:18,320 --> 00:01:25,280
graphics card because in theory every frame of an image in vr needs to

18
00:01:23,600 --> 00:01:29,920
be rendered twice once for each eye

19
00:01:27,520 --> 00:01:35,280
so technologies like NVIDIA's single pass stereo make it so your pc only

20
00:01:32,720 --> 00:01:41,360
needs to set up the scenes geometry once and their lens matched shading actually

21
00:01:38,320 --> 00:01:43,600
cuts off any pixels which would not be

22
00:01:41,360 --> 00:01:46,479
visible anyway due to how the lenses in the headset work

23
00:01:45,040 --> 00:01:52,159
pretty neat then we've got the headset specific tech

24
00:01:49,280 --> 00:01:57,119
like oculus's asynchronous time warp and space warp which kick in any time your

25
00:01:54,799 --> 00:02:01,360
machine can't maintain the steady 90 frames per second that's required to

26
00:01:58,960 --> 00:02:07,360
prevent motion sickness by generating synthetic preemptive frames that act

27
00:02:04,399 --> 00:02:12,959
like a sort of suspension mechanism to smooth out the low FPS bumps

28
00:02:10,800 --> 00:02:17,760
getting this tech working right was quite a bit of work because

29
00:02:14,879 --> 00:02:21,920
gpus are designed for high throughput but not

30
00:02:18,800 --> 00:02:24,400
preemptive frame guessing so oculus

31
00:02:21,920 --> 00:02:30,879
worked with both GPU manufacturers as part of NVIDIA's vr works and AMD's

32
00:02:27,760 --> 00:02:32,400
liquid vr initiatives so it's more than

33
00:02:30,879 --> 00:02:37,360
a catchy slogan now let's introduce our bare minimum

34
00:02:34,879 --> 00:02:45,599
system so we paired uh where is it here it is a core i3 8100 quad core processor

35
00:02:41,519 --> 00:02:48,480
and a gtx 1050 ti and ran future marks

36
00:02:45,599 --> 00:02:53,599
vr mark which has a neat feature both the rift's minimum and vr ready

37
00:02:51,599 --> 00:02:59,360
performance requirements are baked into the results graph and what we found was

38
00:02:56,400 --> 00:03:05,519
that even our bottom of the barrel actually managed to meet the minimum

39
00:03:01,840 --> 00:03:07,840
spec bar so there you go video done

40
00:03:05,519 --> 00:03:13,200
peace out right no no wrong so upon further analysis we

41
00:03:10,319 --> 00:03:18,720
actually found that while our rig was outputting 90 frames per second in the

42
00:03:15,599 --> 00:03:20,080
basic orange benchmark which matches up

43
00:03:18,720 --> 00:03:25,000
with the refresh rate of the head mounted displays in the rift

44
00:03:22,560 --> 00:03:30,799
the actual target is 109 frames per second this is because

45
00:03:28,400 --> 00:03:35,599
aside from the graphics going on on the screen in vr the system also needs to

46
00:03:33,760 --> 00:03:40,159
read sensors and do a bunch of stuff in the background so

47
00:03:37,120 --> 00:03:43,519
with the overhead of vr the calculation

48
00:03:40,159 --> 00:03:47,040
is that 109 frames per second in flat

49
00:03:43,519 --> 00:03:50,319
mode should correspond to 90 frames per

50
00:03:47,040 --> 00:03:51,680
second in vr and superposition basically

51
00:03:50,319 --> 00:03:57,680
said the same thing so that setup was only good enough for

52
00:03:54,560 --> 00:03:58,480
like the very barest minimum spec

53
00:03:57,680 --> 00:04:02,319
so we do need to go a little higher but do

54
00:04:00,959 --> 00:04:06,799
we go for CPU or GPU

55
00:04:04,959 --> 00:04:11,840
well we were watching our CPU load pattern during the runs and our

56
00:04:08,720 --> 00:04:14,720
processor even though it's a measly core

57
00:04:11,840 --> 00:04:20,079
i3 well it is a quad core and it didn't look that busy so we bumped our graphics

58
00:04:17,280 --> 00:04:23,600
up to a gtx 1060 to see where that would get us

59
00:04:21,280 --> 00:04:29,759
usually people would pair such a card with an i5 class chip but

60
00:04:26,639 --> 00:04:32,479
we're focusing on vr here and even with

61
00:04:29,759 --> 00:04:40,080
all the trickery it is still mostly GPU bound and check this out so it turns out

62
00:04:36,000 --> 00:04:43,040
that i3 plus 1060 combo here

63
00:04:40,080 --> 00:04:49,199
actually looks good to go with a super rating in vr mark orange room and a full

64
00:04:46,400 --> 00:04:54,320
bar in super positions optimum preset so that puts our total system cost at just

65
00:04:52,160 --> 00:04:58,720
over 900 us dollars and bear in mind that that is including the Windows 10

66
00:04:56,720 --> 00:05:03,840
home operating system which microsoft recently jacked up to 140 bucks so if

67
00:05:01,520 --> 00:05:07,039
you already have Windows or whatever then

68
00:05:04,720 --> 00:05:12,080
well you can subtract that of course though those are synthetics so

69
00:05:09,520 --> 00:05:17,520
the next step is to go lab rat mode and put this to the test now

70
00:05:14,080 --> 00:05:19,199
normally i game in vr at home on a gtx

71
00:05:17,520 --> 00:05:23,520
980 ti so i will be able to tell the difference if

72
00:05:21,280 --> 00:05:27,680
this doesn't manage to stay as smooth so let's fire up the oculus performance

73
00:05:25,360 --> 00:05:32,080
profiler analysis tool and head up display which should help us pinpoint

74
00:05:29,759 --> 00:05:35,520
the cause of any frame rate drops that we experience

75
00:05:33,680 --> 00:05:41,360
oh cool okay so this is oculus's redesigned home

76
00:05:39,680 --> 00:05:45,520
interface thing now you've got this control panel here that you can move to

77
00:05:43,600 --> 00:05:49,280
wherever it is that you want it to go and then you can uh

78
00:05:47,520 --> 00:05:53,520
go ahead and decide well you know which menu do you want to see oh

79
00:05:51,120 --> 00:05:58,560
close them so there's my library there's my explore tab here then you can kind of

80
00:05:56,320 --> 00:06:02,160
adjust this one over here oh neat you can interact with the

81
00:05:59,759 --> 00:06:05,600
desktop as well oh that's trippy let's go ahead and look at the other

82
00:06:03,759 --> 00:06:09,520
monitor the one that's not capturing my experience right now ah yes

83
00:06:07,520 --> 00:06:12,639
hey you can mess with ivan hey ivan i am opening your start menu

84
00:06:11,280 --> 00:06:16,560
what are you gonna do about it i can touch you inappropriately

85
00:06:14,880 --> 00:06:22,000
oh wait i probably shouldn't open fraps oh that just glitched it out

86
00:06:20,560 --> 00:06:25,280
i don't know i don't know what this thing is yeah thank you

87
00:06:24,160 --> 00:06:30,080
let's go are your monitors different sizes yep

88
00:06:27,520 --> 00:06:34,560
one is 4k one is 1080. dang it ivan game now right

89
00:06:31,600 --> 00:06:37,280
uh walk around the place somewhat because see they've made it social so

90
00:06:36,000 --> 00:06:44,319
you can invite people to come over to your virtual home friends currently zero friends online

91
00:06:42,880 --> 00:06:48,800
thanks that's why you wanted me to open that isn't it all right what's

92
00:06:46,840 --> 00:06:53,039
next i play some robot recall you've played this game before haven't you i've

93
00:06:50,560 --> 00:06:56,560
played vr shooters dang it

94
00:06:54,560 --> 00:06:59,919
yeah it's really fun all right well i think that's good i

95
00:06:58,160 --> 00:07:04,400
think that's all the evidence i need this is working awesome

96
00:07:01,680 --> 00:07:08,400
so for our last trick we're trying out the climb

97
00:07:07,120 --> 00:07:13,360
kind of the the crisis of vr if you

98
00:07:11,680 --> 00:07:18,000
think about it that way like the graphics in this game are

99
00:07:15,680 --> 00:07:23,039
especially when it was first released are pretty incredible compared to

100
00:07:21,280 --> 00:07:25,919
what else there is now what i just

101
00:07:24,639 --> 00:07:30,400
all right oh that's a long way to fall

102
00:07:28,880 --> 00:07:34,960
huh this is maximum settings too

103
00:07:33,120 --> 00:07:41,280
yeah go go go go look at me i'm like superman

104
00:07:38,960 --> 00:07:46,400
superman oh wait oh oh no superman falls sometimes

105
00:07:44,639 --> 00:07:50,479
okay so actually that went surprisingly well but

106
00:07:48,880 --> 00:07:54,800
still the point remains that in a massive surprise to no one just because

107
00:07:52,479 --> 00:08:00,560
a benchmark gives you a good score and you can run many vr games well on a

108
00:07:57,840 --> 00:08:05,039
relatively inexpensive budget does not automatically mean that you can run any

109
00:08:02,800 --> 00:08:08,160
game maxed out in vr it's i mean same idea as in

110
00:08:06,479 --> 00:08:12,720
flat mode right so just like flat mode if you do have

111
00:08:11,039 --> 00:08:16,400
some more budget and you're buying a vr gaming rig it wouldn't be a terrible

112
00:08:14,879 --> 00:08:21,919
idea to bump your specs a little if you want to play uh vr versions of flat

113
00:08:18,879 --> 00:08:23,919
games like fallout 4 and skyrim since vr

114
00:08:21,919 --> 00:08:28,479
is more demanding but frankly i've actually found that the

115
00:08:25,520 --> 00:08:35,519
most fun that i've had is in games that were designed for vr and what's cool is

116
00:08:32,159 --> 00:08:37,919
that the climb in my opinion is more of

117
00:08:35,519 --> 00:08:41,839
a tech demo than an actual game and that one still ran decently

118
00:08:39,839 --> 00:08:46,880
and most of the vr games out there that i've tried some of which are good and

119
00:08:44,159 --> 00:08:50,880
free like robo recall are not nearly as demanding because it's in the developers

120
00:08:48,640 --> 00:08:55,920
best interest to reach as many customers as possible with their games so our pc

121
00:08:54,080 --> 00:08:59,040
right here and of course we're not factoring in some of the RGB nonsense

122
00:08:57,760 --> 00:09:05,680
and stuff like that in our in our cosport but our pc here can enable a ton

123
00:09:02,720 --> 00:09:09,040
of awesome vr experiences exactly the way it is

124
00:09:07,600 --> 00:09:12,399
so thanks to you guys for watching thanks to oculus for sponsoring this
