Linus tech tips coverage of CES 2014 is brought to you by NCI XCOM 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 gonna see is three 4k TVs running an NVIDIA surround powered by four GTX Titans running an 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 for case around gaming at 1.5 billion pixels per second NVIDIA has 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 DirectX 11 point 2 opengl 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 g-sync lately you'll know how excited I am about it and there was some misconception floating around that g-sync was only gonna 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 the 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 yeah there it is as soon as we go over a populated area it starts to really stutter because it's dry bring down to 30fps due to the variance in how quickly the GPU can process these easy frames versus those more difficult ones now we're gonna go ahead and press the button again and I believe this is gonna drop us it 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 framerate but what happens when we go over that say oh look at that vertical tearing alright one more time here one more time here okay so where the water smooth smooth all that tearing very very very or awesome very awesome kay 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 g-sync we're not gonna see any lag and we're not going to see any tearing the little green dot 60fps over the water nice and buttery smooth passing over the land oh wow look at that nice and smooth because instead of dropping down to 30fps we were able to drop down to any frame per second because g-sync 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 NCI XCOM for allowing us to be here at the show remember they're your source for great technology selection and 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 guys this content
