00:00:00.080 --> 00:00:05.520
you probably already know that if you want a game in virtual reality on your

00:00:03.360 --> 00:00:09.760
home computer you need a powerful enough graphics card and you've been inundated

00:00:07.839 --> 00:00:14.160
with information about just how much money you should invest in one but what

00:00:11.679 --> 00:00:18.080
about the CPU are there any special considerations you should take into

00:00:15.599 --> 00:00:21.680
account for your vr rig or can you just plop in any chip that isn't bargain

00:00:19.840 --> 00:00:27.840
basement quality and be done with it we're going to answer that question today and thank our friends at oculus

00:00:25.760 --> 00:00:32.559
for sponsoring this video about this topic let's start with some simple

00:00:30.160 --> 00:00:36.960
advice check the recommended specs on the vr headset manufacturer's website

00:00:34.640 --> 00:00:41.360
and make sure that your CPU is at least up to that standard but seeing that you

00:00:39.360 --> 00:00:47.360
might find yourself thinking well the listed CPU actually isn't all that high

00:00:44.239 --> 00:00:51.280
end for example oculus only recommends a

00:00:47.360 --> 00:00:53.440
2014 vintage core i5 4590 for their rift

00:00:51.280 --> 00:00:57.360
s which is their current pc connected offering at the time we shot this video

00:00:55.440 --> 00:01:01.920
unfortunately that doesn't mean that it's a good idea to only pay attention

00:00:59.760 --> 00:01:06.240
to the recommended spec you see the reason that vr headsets need powerful

00:01:04.080 --> 00:01:11.200
hardware is because you need to push more pixels than a standard gaming pc

00:01:08.960 --> 00:01:16.479
for example the aforementioned rift s has a 1440p display that runs at 80

00:01:14.080 --> 00:01:21.520
hertz and while those specs might be a luxury for conventional gaming it's more

00:01:18.720 --> 00:01:26.400
of a baseline for virtual reality this is because lower resolutions and frame

00:01:23.920 --> 00:01:29.280
rates in vr aren't just an annoyance they can break immersion to the point

00:01:27.920 --> 00:01:33.520
where you'll actually get motion sickness so if you thought stuttering in

00:01:31.439 --> 00:01:37.439
regular games was irritating just wait until you're throwing up on your living

00:01:35.200 --> 00:01:40.320
room carpet because of slowdowns in a vr title

00:01:38.560 --> 00:01:44.479
this also means that there's more to consider than just making sure that your

00:01:42.079 --> 00:01:49.200
GPU is pushing out enough frames you want to have good and consistent frame

00:01:47.119 --> 00:01:53.040
times meaning each frame will be displayed on the screen for roughly the

00:01:51.200 --> 00:01:57.280
same amount of time for smooth animations without stutters and

00:01:55.360 --> 00:02:02.159
inconsistent frame times can be caused by a number of things one of which is a

00:01:59.680 --> 00:02:06.079
CPU that can't keep up with handling and scheduling all the data that it sends to

00:02:04.000 --> 00:02:10.160
your graphics card you see the CPU has to give the GPU something else to work

00:02:08.160 --> 00:02:14.319
on once the GPU is done rendering a frame and if your GPU is spitting out

00:02:12.480 --> 00:02:18.480
tons of frames per second like you would need to gaming vr the CPU is going to

00:02:16.640 --> 00:02:22.800
have a harder time keeping up if it isn't up to scratch traditionally

00:02:20.560 --> 00:02:27.920
rendering requests such as draw calls were single threaded but newer apis like

00:02:25.520 --> 00:02:32.560
directx 12 allow draw calls to be spread over multiple threads so unsurprisingly

00:02:30.480 --> 00:02:36.800
it can really help in vr to have a couple of extra cores and a little more

00:02:34.959 --> 00:02:41.040
speed than whatever the recommended specifications are and this is

00:02:38.720 --> 00:02:43.760
especially true if you are streaming in vr

00:02:41.920 --> 00:02:48.400
even if you're using your graphics card to encode your video stream instead of

00:02:45.680 --> 00:02:52.720
the CPU your CPU still needs some dedicated cores to handle receiving the

00:02:50.400 --> 00:02:56.800
encoded frames from the graphics card especially when you consider that the

00:02:54.080 --> 00:03:00.879
CPU already has to work a bit harder not only due to the frame time issue we just

00:02:58.480 --> 00:03:05.200
discussed but because it's more taxing for your CPU to handle vr head tracking

00:03:03.360 --> 00:03:09.760
than it is to simply process keyboard and mouse inputs with a conventional

00:03:06.959 --> 00:03:13.760
game so given that six cores is a baseline for modern gaming rigs

00:03:11.760 --> 00:03:18.400
especially as games are becoming more and more complex and better at taking

00:03:15.840 --> 00:03:23.680
advantage of multiple course we'd say an 8 core modern architecture processor for

00:03:20.640 --> 00:03:25.200
vr is probably a good bet and a 10 core

00:03:23.680 --> 00:03:27.920
wouldn't hurt if you're streaming with CPU encoding

00:03:26.720 --> 00:03:31.519
you know what else wouldn't hurt listening to today's sponsor bit thanks

00:03:29.760 --> 00:03:35.280
again to oculus for sponsoring today's video if you don't want to worry about

00:03:33.120 --> 00:03:39.680
picking out the right CPU then check out the oculus quest 2. it doesn't need a pc

00:03:37.920 --> 00:03:43.440
because it's oculus's most advanced all-in-one vr system and gives you

00:03:41.599 --> 00:03:48.080
blazing fast performance next-gen graphics and 50

00:03:45.599 --> 00:03:53.280
more pixels than the original quest each panel has a sharp 1832 by 1920

00:03:50.799 --> 00:03:58.239
resolution powered by the snapdragon xr2 platform all in a headset that manages

00:03:55.440 --> 00:04:02.799
to be 10 lighter than the original quest there's also new touch controllers a

00:04:00.159 --> 00:04:07.200
built-in ipd adjustment mechanism and it's backwards compatible with all quest

00:04:04.799 --> 00:04:10.239
titles you even get pass through plus which enables you to check your

00:04:08.400 --> 00:04:15.120
surroundings whenever you step outside of the guardian system and if you do

00:04:12.159 --> 00:04:20.000
