unless you make a habit of living under a rock or if you're just not that into gaming that - you've probably seen the headlines AMD freesync working on geforce cards and it's true but there's a catch so the current methods for enabling free sync on a GeForce graphics card require you to also have an AMD GPU in your system that is capable of supporting freesync itself so today's video then has us trying it out to see if it's worth the hassle to save money on a g-sync monitor and while we're at it we were thinking maybe we'd try to run g-sync on an AMD graphics card rose wills new prison s500 case lights the way with its array of RGB fans tempered glass panel and spacious interior click the link below to learn more so let's start with how this works there are actually two different ways to go about this there's the GPU a-and the APU way so we'll be using the APU method for the uninitiated and APU is AMD's name for a CPU that has a graphics processor built into it now normally as soon as you install a dedicated graphics card your onboard graphics gets disabled because who would use that when you can use this but for what we're doing we actually need to force the Vega 11 GPU that's built into our Rison 520 400 G on so we're gonna change IG FX multi-monitor to enabled and we are going to set the primary video device to our onboard graphics let's go ahead and reboot now while we wait for that to happen let's talk about what's going on under the hood here if you watched our gaming on Linux video a little while ago we showed a piece of software called looking glass that wendel from level 1 Tex was using to game with very low latency in Linux by running the game effectively in a virtual machine that was running Windows and then capturing its output TLDR the API that Windows is using here is called DX GI and what it does is essentially mirror the output from one card to another with very little delay though there is still a delay so as you can see here we've already got our geforce driver installed and working so the next thing we need to do we've already downloaded it here is install the drivers for our Radeon graphics now that our Radeon drivers are installed which yes is working correctly we need to change our display configuration a little bit here so what we want is our free sync monitor plugged into our onboard graphics and we want nothing plugged in to our GeForce graphics card one cool thing by the way is that because of the way that this works in theory we could actually do the same thing with Intel's upcoming integrated graphics with free sync support that's not confirmed at this time yet though so now that all of this is done we can go into our display settings then on the bottom we're going to see an option here for graphics settings now all we need to do is add whatever we want to run here okay so now we go into options and then we just need to set our graphics preference so we're gonna set that to high-performance right about yeah see here's our power saving GPU here's our high-performance one now when we launch this demo theoretically freesync technology will work we can actually test it to check this out so let's go ahead and turn AMD freesync off oh we got to turn vsync off okay there we go that's more like it now it's turning free singing off and boom there's our tearing let's go ahead and do an FPS sweep so we can get some really nasty tearing there yep now let's turn freesync back on right alright let's try counter-strike so V sinks off let's see how smooth this is so in theory this DX GI thing only adds about one to two milliseconds of additional legs so for the people out there claiming they can feel the difference okay maybe but you're probably superhuman because at 60 frames per second that is what does that work out to wait oh wow this feels like ass I think this is running on the wrong GPU so it's a little clutch every one of your there we go for every one of your programs you're gonna have to actually change that let's see if we can just remac summize it and it'll run on the right one yeah that super did not work let's try relaunching it there we go that's more like it alright I am getting a friggin mess ton of tearing here when you're running free sync are you supposed to enable vsync within the game oh well there's there's our problem also the developer console isn't enabled for cryin out loud one problem with csgo though is that it's not demanding enough for us to dip below sixty frames per second so it's not really giving us a benefit over just running vsync other than theoretically a little bit less lag so what we're gonna do then is we're gonna fire up Deus Ex mankind divided can really tell us but much smoother wow I suck all right so here we go now we are right in the sweet spot where we're gonna be benefiting from our free sync display where we're not quite able to maintain 60 frames per second but we're right in that 45 to 50 FPS range what kind of annoying thing about this game is it has some on-screen effects that kind of look like tearing but we're not I'll see you like that but that's not bad that's me dying I can't believe that this is working like this just blows me away okay so remember how I said that because of the way this works we could in theory use Intel's eye GPU for free sync with an Nvidia card actually churning through the frames once those come out that got us thinking what if we did it the other way around what if you're on Team red so you're running like a Vegas 64 but some baller new gaming monitor is only available in a g-sync flavor Wow that happened so fast I didn't even get a chance to show you guys check this out so as soon as we plugged it in boom g-sync display connected what so go ahead and fire that up and able T sync and able do you think for all the things now all we have to do is the same process but in Reverse going into our graphics settings and going okay csgo we don't why I performance we want power saving now we can launch counter-strike and in theory will be running g-sync through our Nvidia graphics card but will actually be rendering with our onboard graphics now that wouldn't make a lot of sense in this case but if you were running something like Vegas 64 and then you just installed like a geforce 950 or something in another slot you could make it work whether or not you should make it work is another question though because unless someone automates this GPU switching process it is a bit of a pain in the butt at least at this time and it's not that cost-effective because one way or another you will have to have two GPUs would you look at that it feels a little laggy but that's because we're running at 33 frames per second there's no tearing and it's as smooth as it could be given the situation now one way that you could make this solution make sense would be if you had some old compatible hardware lying around or actually maybe if your team green in terms of your gaming rig but you wanted to hook your gaming machine up to one of Samsung's freesync TVs for example because until BFG DS actually make their way to the market there are no large format g-sync displays that could be pretty cool but in most cases you'll probably end up spending more than you are actually saving or very close for what isn't an amazing experience the real takeaway is that we shouldn't have to do any of freesync and visa adaptive sync are both industry standards at this point and NVIDIA if you're listening we're not saying that you need to ditch g-sync we know that you guys have special green g-sync sauce that you pour on it that makes it a little better in your opinions personally I haven't looked at with it with a high-speed camera yet but you guys think it's better so ok we're just saying that like CUDA and OpenCL there's no reason that you couldn't support both especially since as we've demonstrated here there's no physical link reason that you couldn't support both team group is sponsoring this video with their delta r gb SSD yes my friends it's an r gb SSD they've got three versions available so the USB gives off a rainbow wave while the 5 volt and the 12-volt are able to be configured with a variety of RGB software they've got read and write speeds of up to 560 megabytes per second and this is pretty cool if you click the link below you can enter a giveaway and the winner can choose either a 500 gig Delta R GB SSD or their T Force RGB 16 gig ram kit so thanks for watching guys if this video sucks then I see you
