hey everyone this is Steve from gamers Nexus Donna and we are here on the floor at CES 2014 so this is our first official day on the floor you saw some of our msi footage now we're here with him nvidia to look at g-sync and i am joined by Vijay Sharma working on g-sync Vijay what can you tell us about how how jisuk works from a top level and maybe give us some technical details great yeah jisuk is a new technology that delivers the smoothest tear free gaming possible are really excited about it and we've got partner monitors on display here today at CES which will be available in q2 so how g-sync works let's start with how traditional monitors work and in a traditional monitor if we think about a 60 Hertz refresh monitor it is expecting 60 frames per second from the source or the GPU consistently and the GPUs however in most modern games don't output at a constant framerate frame rates vary so if you think of a really simple scene a GPU can render that very quickly but if you have a complex scene the GPU might take longer and so frame rates vary a lot and when frame rates vary and the monitors expecting a consistent frame rate a few things happen with vsync on you get stutter because the the monitor re displays the previous frame and any time that happens to get the stutter so you can turn vsync off and if you turn these sync off you get something else you get tearing and you've probably as you've played games experienced tearing on the scene where you have these these horizontal lines ripping through the scene what g-sync does is as soon as the GPU is done rendering a frame it sends it to the display and what that does is it eliminates tearing eliminates display related stutter and really importantly for gamers it minimizes the input lag versus vsync on so you get very fast response time as you're as you're playing a game and so that's basically what g-sync does is the monitor slaves off of the GPU the GPU drives monitor timing and what's our normal monitor time for a frame delivery what it when is the monitor expecting a frame from the GPU right so on a sixty Hertz refresh rate display your the monitors is expecting a frame every 16 milliseconds or so and on a 120 Hertz monitor it's about every eight milliseconds or so okay and in terms of availability we know we have some of these announced here at CES where should our gamers be looking for g-sync enabled devices sure so today on on display we have six announced monitors from partners such as a sous BenQ viewsonic Philips and they will be available in q2 so really looking forward to that and let's say I already have a monitor I'm happy with any chance of a modular kit anything you have for us yet we have talked about a deal a do-it-yourself kit and the kit is for one specific model of a sous monitor it's a VG 2 for 8 QE and what the kit is designed to do is modify that monitor to be a g-sync monitor now this is a kit for really core enthusiast gamers that we built it so that we could get g-sync into their hands as soon as possible because like many gamers we don't want to wait and so you can do that do that now you should be familiar with modding so it takes a bit of skill and it you should be a real enthusiast if you want to go do this it should be available on our website by the end of this week very cool so I think that covers actually a lot of you guys check out the links in the description below for full article coverage and we'll have some slides in there as well that show more of how g-sync actually works in terms of the frame delivery so you can get a visual representation of that and yeah thanks again we will see you all next time peace
