great technology selection and service along with Corsair memory and Western

Digital NVIDIA is starting things off on a strong note when you walk into their
0:13
Booth the first thing you're going to see is three 4K TVs running in NVIDIA
0:17
surround powered by four GTX Titans
0:20
running in NVIDIA SLI and you are going to see project cars a game being played
0:25
by real people so this is not some kind of you know random Tech demo or anything
0:30
like that running at a very smooth frame rate speaking of smooth frame rate if
0:34
you look up above me you can see right there 4K suround gaming at 1.5 billion
0:40
pixels per second NVIDIA's got tons of
0:45
stuff they're demoing here game stream with Shield is obviously a big thing we
0:48
went in the back room when we checked out Tegra K1 they've got some amazing
0:53
demos running with face works as well as with Unreal Engine I mean it's a truly
0:57
direct x1.2 open G4 4.4 compatible
1:01
Graphics chip using Kepler the Kepler architecture Inside a Mobile form factor
1:05
so that was super amazing but really I mean if you guys have heard me talk
1:09
about gsync lately you'll know how excited I am about it and there was some
1:13
misconception floating around that g-sync was only going to support 1080p
1:17
TN panels but that's totally untrue
1:20
they've actually got a wide variety of different partner Solutions most of
1:24
which will be coming out this year with support for g-sync but the one that
1:28
really grabbed my attention is is the uh pre-production one here at the end of
1:32
the line so they've got two ASUS 4k monitors running here one of them's got
1:37
their pendulum g-sync demo and that's interesting but we've seen that before I
1:41
wanted to show you guys the real world demo because normally you can't really
1:45
demo g-sync on video but in this case they've actually found a game that in a
1:49
real world scenario demos it incredibly well so they've built a little app that
1:53
Cycles between the different sync modes so you just press page up and right now
1:57
we're running in vsync mode so you can see we're here over the water fraps is
2:01
giving us a clean 60 FPS and everything runs butter smooth now as soon as we oh
2:07
yeah there it is as soon as we go over a populated area it starts to really
2:12
stutter because it's dropping down to 30 FPS due to the variance and how quickly
2:17
the GPU can process these easy frames versus those more difficult ones now
2:22
we're going to go ahead and press the button again and I believe this is going
2:25
to drop us yeah there we go so we're up at around 78 FPS over the water
2:30
still looks very very smooth over the water where we can maintain that frame
2:34
rate but what happens when we go over that City oh look at that vertical
2:37
tearing all right one more time here one more time here okay so we're over the
2:41
water smooth smooth oh that tearing very very very awesome very awesome okay you
2:45
can see it like sweeping back and forth so that's what happens with vsync
2:49
completely off now here's the last example with gsync we're not going to
2:53
see any leg and we're not going to see any tearing a little Green Dot 60 FPS
2:58
over the water nice and buttery smooth smooth passing over the land oh wow look
3:03
at that nice and smooth because instead of dropping down to 30 FPS we were able
3:07
to drop down to any frame per second because gsync lets the graphics card
3:11
control the refresh rate of the monitor so if it's running at 42 frames per
3:14
second that monitor is running at 42 refreshes per second very very cool guys
3:21
don't miss any of our CES 2014 coverage big thanks to nc.com for allowing us to
3:26
be here at the show remember they're your source for great technology selection service we have a couple of
3:30
other sponsors Corsair memory as well as Western Digital huge thanks to them as
3:34
well because without them it wouldn't be possible for us to be here bringing you
