Sweeney, Andersson & Carmack discuss NVIDIA G-Sync

2013-10-20
these are the three people we've invited to come and talk to you about Jesus now the reason why we invited these three people Juve ZZ Top and Hollywood beauties it's because they also happen to be some of the most important contributors to modern 3d graphics I think as soon as you realize who they are there will be no question that they have contributed more demonic computer graphics and just about any money the mass contribution to the number of people exposing them to computer graphics if not for their work our reward point have been possible if not for their work our contribution wouldn't have been possible these three game developers are true artists in every brain amazing technologists in their contribution to the industry to the world is now completely unquestioned it has never been that all three of them have been in one place at the same time these three luminaries i am sure are your heroes they're surely mine and this is the first time that they in fallen in love simultaneously with a technology that they believe is as important to the future computer graphics that they wanted to come and share the stage together and tell you guys how they feel about this revolutionary breakthrough we call GC ladies and gentlemen can we bring out our special guests sweetie welcome what do you guys think on talk about cramsey morning can the muse getting up yeah these guys are really really amazing now if we cantle up when you get when you get John Johan and Tim on a stage can we just all agree we're not going to rehearse they're going to say whatever they are going to say okay and that's that's really great and I want them to tell you how they feel about this technology so maybe anyone is doing for them from this side out so it tends to stand out here so they can all see it and you want to do you know what it is Carly they're a little awestruck by the southern Bertie of you guys so you know I know I know it's not I notice you guys you guys don't feel you're Brad Pitt but to them you want plus two months you are alright so now here on the shadows and so so so ten what we just when we start first of all some of the challenges in computer graphics I think I think the audience would love to hear about your reaction jisuk move aside what do you think of our communications of g-sync you know that now that's what he needs to happen so most questions this one of the students of gravity name is what it is infants not recognizing benchmarks but it's currently important two layers experience and detectives all games an opportunity to the gene that previously had to work commencing heart is make a lot of sacrifices to give advice today six defendants happened when she said you can hit any reasonable frame rate and potentially get to take level Instagram pics it's one of those magical moments to play a game and the CM is created is completely free of architect yeah it's like is in my zone for the first time just having this very seamless experience you can't recognize instantly what's happening this makes it so nice but you can see it as orders above the previous experience Wii U is going to happen again how's ur game developer when you have technology like this how would you think about it differently everything freezes up the game developers take much more immersive experiences without this we have to make you know if you're aiming a steady 60 frames a second in the last generation we would have to absolutely assure that every single frame its target where is what do you think we have a lot more with over on each side because in this continuum of performance anywhere between 30 to hundreds of pages happened early Mabel continue to operate smoothly and without apartment that's cold you know what were you think tell us tell us your feelings about G sanken and as you think about G saying what it for the implications to the future of gaming and how would you develop Kingston point it's pretty awesome it's really it changes the reception quite a bit and I was really surprised by that why should you see in action which we were terrible well it is that the best possible experience you get a gift before running 100 FPS in the game when typically without decent of people do that's sort of what we used to be the best possible type of experience but with this well you don't it's continually changes the actual perception of the picture you see a continuous stream over something that you might actually interprets as a pitcher and really like that were surprised by how my left to interpolate tended information and we tried it out and just that or more people in nice to just as everyone this is graduating what everything's going to happen to this one comes with widespread attention I think one thing that has not been reflected in engage the Timbers int'l bit of okay we design games for some specific budget other games nowadays are not really the games you played 15 years ago or even 10 years ago 25 years ago is now are these massive experiences of very different types of environments that happen to me sometimes you have a cutscene and sometimes you have to adjust our feel that we're traveling through and sometimes here you have massive amounts of explosions and it's essentially possible to design a game for a fixed frame rate today and you don't want to get to make massive compromises in all areas even if we think I'll remember all game runs at 60fps you have to run rather than 114 he'll sacrifice a little budget for six that Kathleen predicted are immersed and this what we don't really need to do the same way sure you probably don't want to jump to bunch of fragrance but if the storytelling and national game experiences are that before and this technology is actually much easier to make the games they actually want an expensive want and still again we need to get a picture of Turkish that's really cool fanatical about displays as John Doe easy for that is because he's putting them awfully close to his eyes these days and when he saw he wanted to come out and share with sure his opinion with you guys it is his first reaction because John what do you think anything's going to happen first hicistes had willful blind spot to the artifacts of Terry and Jennifer where we can talk and try to get people excited donkeys are relatively subtle effects like gamma correction and subsurface scattering and some of these things that we can spend tons of you know flops on and kind of point out squid say this is really important while why do you know covering our eyes over the huge Gator line racing up and down the screen it was really really egregious artifacts and yeah I've been a lot more sensitive about this for a long time we did make thing the decision to make those compromises our last title with new 60 frames per second which meant that we didn't have this fifteen twenty percent cushion and we had to make sure that we wouldn't I see that we would only very rarely wind up missing that which meant that for me given amount of processing power targeted for maybe twenty percent or more in many cases a lot more was just left completely unused because we were at the maximum 40 60 frames per second and that was important for the smoothness that it gave us we had to make a lot of compromises to make that happen and being able to use all graphics power with you got to unlock it from 60 and open up towards the higher frame rates and to be able to make it a smooth continuum there rather than dropping from 60 count to 30 and one huge lurch are suffering the stuttering or suffering the tearing it's just a better experience in almost every single game and benefit from this we're being able to go over 60 frames per second lines up bringing in additional benefits and once we start crossing something magic numbers above 90 95 heading towards 120 and we started dating with the little persistence builder and so it makes things and digital benefits that you haven't received here today so I mean that you sync technology involves not just the variable refresh but also is a remote assistance which would have additional benefits as can start moving towards those higher agreements but the only way you're going to get things towards those higher frame rates is why having this smooth incremental path video we could ship an old name repaid like doom 3 bfg they can run a hundred twenty frames per second but the only way you're going to start seeing absolute bottom triple eight is if they can creep up and at 16 that 70 then somebody's got a reason to get some crazy to elicit as an ally system that's going to go ahead and spend another five hundred dollars on video cards but oh my god it was this at 120 per second load resistance that's going to be awesome absolutely
