0:00 Linus Tech tips coverage of CES 2014 is brought to you by nc.com your source for
0:05 great technology selection and service along with Corsair memory and Western
0:09 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
3:38 guys this content
