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