this is my magnum opus of over a year of testing various different displays using both Nvidia as well as AMD gpus and a 1,000 FPS camera and what I found is definitely going to shock you guys it turns out when set up correctly you can actually have far lower latency and a better image in motion all while using less PC resources how well it all has to do with sending the fastest most up-to-date frame your PC can produce without tearing and unfortunately the default settings for gpus and games don't allow this to happen now this journey all started with me testing various FPS caps and what I found was that yes the old adage of vsync adding tremendous latency in games was actually true however at the time I also found that g-sync plus vsync in the Nvidia control panel plus reflex in game could actually lead to far less input delay on many games and in fact was overall better than using an external cap in the driver or Reva tuner statistic server to set a global limit not only that but you would also get a tear-free experience using these settings and it could actually be even faster than no FPS cap as when you're heavily GPU bound this can actually increase latency however viewers then pointed out that external caps can have higher latency than in-game caps so I went to investigate this claim Now using an AMD GPU and found that they were actually correct in-game caps led to far lower latency than any other method however I still hadn't had a chance to revisit this on Nvidia gpus to see if this is actually better than gsync plus vsync plus reflex so I recently did just that now for these tests I ran four different configurations on a 138 HZ OLED monitor g-sync plus a vsync plus ultra low latency mode g-sync plus vsync plus reflex gsync plus vsync plus the 133 FPS cap that Nvidia wants to set it to when you use reflex but of course without reflex and then finally gsync plus a 120 FPS cap as in my testing it turns out that vrr used by g-sync and freesync monitors actually need 1 millisecond of time to fully work what I mean by this is for you to get zero perceivable tearing you must add an additional millisecond of latency to give the display more time to process this is done by first getting the latency of your monitor which for me as an example would be to take 1,000 milliseconds as there's 1,000 milliseconds in a second divided by 138 fps to get 7.24 6 milliseconds of total latency you then add 1 millisecond to this number which would give us 8.24 6 milliseconds of total latency and understand what that frame rate is we simply take 1,000 milliseconds again divided by this new latency which gives us 121.2 7 FPS however I then round down to the nearest even number to give it a little bit of headro which means that actually the max frame rate we can run on a 138 HZ display is 120 FPS other common refresh rates would look like this 240 HZ = 192 144 HZ = 124 and 12 HZ equals just 106 when I was testing AMD gpus I found that if you don't do this you will likely C sight tears at the bottom of your screen which can make the display look a little weird and throw you off when you're playing a competitive game however on an Nvidia GPU I found that if you combine gsync Plus vsync in the driver you actually only need to add 0.3 milliseconds of latency for vrr to work correctly so for example 240 HZ = 223 144 HZ = 138 and 120 HZ equals 115 So in theory unless AMD can do the same thing Nvidia may be able to deliver High higher untorn frame rates but that's only if the latency is still good and is it well let's find out and first starting off with OverWatch 2 and right away I could tell something was going wrong with ultra low latency mode in the driver using the latest drivers as 41 milliseconds of total system latency is actually up to roughly 46% higher than the best result which was gsync plus vsync plus the 133 cap as that came in at just 28 milliseconds and was shortly followed by the 120 FPS cap plus gsync and no vsync for that same 28 milliseconds and then in third place was actually gsync plus vsync plus reflex at 32 milliseconds then moving on to Apex Legends and here things were definitely a lot less weird it seems like everything's working as intended as gsync plus vsync plus reflex or ultral low latency mode both gave the same 26 milliseconds of total system latency It Was Then followed up by the 120 FPS game cap Plus g-sync at 27 milliseconds then in last place at 28 Mill seconds was gsync plus vsync plus the 133 cap so basically these results are all the same probably margin of err stuff here but then moving on to fortnite and once again ultra low latency mode is completely broken 61 milliseconds is around roughly 2.35 times higher than the g-sync plus vsync plus reflex result which was also the best result at 26 milliseconds the other two basically the same 27 and 28 milliseconds and then finally we have the finals and once again ultra low latency mode seems to to be broken and what's going on here is I found out that it's no longer capping the FPS below the max refresh rate it's just letting it go to the max refresh rate which seems to then be engaging vsync at all times leading to terrible latency and a just overall bad experience but in third place we had gsync plus vsync plus the 133 cap then in second place we had gsync plus vsync plus reflex and then in first place we had g-sync no vsync and a 120 FPS in-game cap and overall taking a look at the final results here yeah ultra low latency mode definitely broken on the latest driver or maybe it was intentional that they stopped capping the FPS but either way you SI it if you don't cap the FPS with ultra low latency mode you're going to get really really high latency I mean it is 61% higher than the best result now the second worst result was gsync plus vsync plus the 133 cap but I say second worst realistically it's near margin of error stuff to the other two results gsync plus vsync plus reflex was technically 1 millisecond faster and then gsync plus the 12 20 FPS in-game cap was technically the fastest at just 2 milliseconds faster than the reflex result so honestly guys overall it seems like these three options are going to give you pretty much the same amount of latency so what's the conclusion here and first of all do not use ultra low latency mode it just seems to be really weird and I don't want to tell people to use something that they're going to have to be fiddling with a lot to make it work correctly now the second thing is please always use vrr sure you can technically get a lower latency experience if you far exceed your maximum refresh rate and at really high frame rates the tearing isn't that noticeable but you're still getting tearing and if you're GPU bound your latency is actually going to be worse as I've proved in the past so unless you can just cap 1,000 FPS at all times and have your GPU at like 50% it just doesn't make sense for the vast vast majority of Gamers and then three g-sync plus vsync plus reflex or gsync plus vsync plus an in-game FPS cap 0.3 Mill seconds below your max refresh rate for nonreflex supported games is the best mix of image quality in low latency you can get a cleaner image in motion with no tearing at the same or lower latency than uncapped FPS while needing less performance because you don't need to be driving 500 FPS and you could end up getting the same latency at you know like 138 FPS because you're no longer GPU bound which means that yeah you don't necessarily need to buy more expensive gpus unless you want want your image to look better with a higher resolution or higher settings and then finally for a low latency tear-free experience on AMD capping your FPS in game 1 millisecond below the max refresh rate rounded down to the nearest even number is the absolute best way to play your games consistently however it may be possible to do free sync Plus vsync in the control panel like Nvidia and I will investigate this in a future video definitely let me know in the comments below if this is a possible combination but hopefully that helped you guys out again definitely recommend favoriting this one cuz there is a lot of hours of work that went into this to finally get down to what the best settings are and yeah this is some shocking stuff if you set it up correctly you're going to have a cleaner image in motion lower latency overall and now we know that you know what Nvidia might actually be able to technically give you higher untorn frame rates I'll have to look into that a little bit more but if that's the case that's actually a pretty big deal if you made it to the end of the video be sure to drop a like every time you do so AMD and Nvidia release new gpus also
