I feel like Nvidia Reflex exists because of your testing, and you'll never get official credit for it. So I'll just thank you personally.

This guy definitely deserves more subs ! He is the hero we all needed when it comes to gaming ! The video quality, data processing and nice readable graphs are on the level of Tech Jesus himself !

Comment: _"Radeon BOOST is NOT meant to reduce system latency! That is what Anti-Lag is for!"_ *FYI:* It was AMD who positioned Radeon Boost as *"Ultimate Latency Reduction Technology"* - more powerful than Radeon Anti-Lag according to their own slides. I thought the snip from the press conference I included 4:42 made that clear, guess it didn't - however this should: twitter.com/BattleNonSense/status/1373021156345847813

I was always convinced that limiting the framerate to get below 100% GPU utilisation is more advantageous than a few extra frames, but had no way to prove it. Thank you for this comprehensive analysis!

As always, thanks for the real testing with all this hard work! Keep it up and thanks for the video!

Incredibly in-depth as always. Great job and thanks for this useful video!

Your analysis is so organized and clear...Thanks!!!

Underrated channel - you should make a video on testing CRT monitors vs modern flat-panel monitors. That would be very interesting

Nvidia GeForce Twitter just shared your video. Nice.

We can't thank you enough for your hard work.

Thanks for covering this topic. It was interesting to listen to!

Superb video as always, you are on another planet, so much work, quite spectacular.

Fascinating stuff, and it's completely changed my approach to configuring my frame-rate limits (which I've typically done to reduce system power consumption for games that do not require high frame-rates).

Thank you for all of your hard work making this useful in depth video for us!

I been watching since very early on before I even built my pc. First monitor I bought was Gsync and religiously been following since. Thank You for the Tests!

I would like to have a look at system latency and what could effect latency in games. Things like spatial sound virtual 7.1 or higher bit audio, full screen optimization, GPU scaling and image sharpening on older Nvidia cards. There are also some people saying that discord voice chat or any background desktop application can increase latency especially on low thread count CPUs (4 threads). Also something like G-sync VS No sync VS scanline sync that comes with RTSS in term of latency on caped stable FPS count. I personally found all these fake info around the web and even if there was any latency difference it would be like no difference, but I want it to be proved. There is also an MSI tool that change system scheduling for certain stuff like setting higher priority for the graphic driver and I am not sure if it really does anything. This could be an interesting topic for u in the upcoming video. I would love to see that. Thank you very much for all precious info we got from u.

Great video as always Can we by any chance get a short summary video of what are the most Important settings you need to make to let a game run optimally? Basically summarizing all of your videos on this topic and allowing us to reference a video that contains everything one might need without it containing that much background information :)

Conclusion for Nvidia cards: Always *off* in Nvidia Control Panel *Enable* in game settings if it supports it. *Cap Frames* in game if it doesnt supports it. Thanks dude

Love the content as always Chris. I've used Afterburner as a framelimiter for some time, any thoughts on using it or an external equivalent outside of the game? Thanks

Thanks Chris for the explanation of the functionality at the beginning of the video. I thought it was a marketing gimmick but it's some actual usable technology. 👍🏾

Hey Chris, as always, your content is awesome. Quick question then : We know that we have input latency increase in a G-Sync enable scenario with framerate at the top-notch of the monitor (for example, when your framerate touches 165Hz on a 165Hz monitor with G-Sync enable, you increase momentarily your input lag then). What's the setting to use then? NULL OFF / G-SYNC ON / V-SYNC ON / In game or RTSS FPS limiter ON at 158Hz to prevent G-SYNC ceiling and REFLEX ON in game? I hope my question is not too hard to understand :D ! Cya

Amazing breakdown, so comprehensive

Broooo you are the must youtuber care about the knowledge at this area thank's u 4 real u make a hard work . Hope see more and more from you

You are the hero we need!

Interesting as always. Great to see amd and nvidia taking this seriously (thanks to you no doubt!) For me using a frame rate limiter and having rock solid frame times is the most practical and transferable solution for all games. What I would like is a setting for target frame rate with solid frame times in game that adjusts resolution and settings dynamically to achieve this. Until then I am happy to find the settings that give me the most stable performance.

Did you disable fullscreen optimizations for any of these? Awesome video btw.

Treasure trove of info do keep making these man

you could make a video showcasing the input lag effect of the parsec latency in a local network with and without wifi, it would be pretty interesting

Fantastic video as always, liked

Good video, you covered everything I think.

Starkes Video wie immer! :)

You are doing god's work. Thank you so much.

Well done!

You still plan on making a video comparing keyboards and input lag? :) I would love to see more Corsair comparisons like you did a bit of in the last video! :)

Hi! thx for this video. Do you know if super rendering increase input lag?

Remember when battle)non)sense used to do netcode videos for games ?

So for AMD Users keep using AntiLag, cap frames in game where your card is more stable and for the moment avoid Radeon Boost. Thanks for the video!

thx you deserve more subscriber

Awesome work. Your patreon link is broken btw.

good work!

Thank you so much , love your channel ❤️ as a conclusion, for me an AMD user i should enable anti-lag and 'try and error' to find a frame rate that my pc can maintain consistently in each game .. am i right?

Hi man. great in-depth testing! I got a question. I play Apex legends and I quite dont understand the difference between reflex ON vs reflex+BOOST. And looking at your data, it seems having reflex ON is better than reflex+BOOST (tho just barely a difference). using gtx1660 in a 1440p resolution at 144hz.

Good Video as always

2 Questions: Would setting max power to 95% help NOT getting gpu bound? Would adaptive power management help in any case where you do not want to be gpu bound?

I'm with you up to the point where you start wishing more games add proprietary features instead of just improving their rendering pipeline.

Thanks for the awesome explanation! I just have 1 question, does it matter if NULL is set to ON while reflex is also on in a game?

Great video!

Thanks for what you do!

I am curious about the frametime consistency when comparing with (RTSS) using the nvidia reflex , can you tell me an avg and how much standard deviation does it have comparing to RTSS? (Let's say you cap the framerate at 90% load on GPU as the maximum limit using RTSS) Is the frametime all over the place with Reflex? Why I ask this: You said the in-game framelimiter has bad frametimes (Inconsistent) so I am trying to get the best of the best in terms of options (G-sync/Free Sync) + No GPU Bound (let's say best of both worlds, no tearing (SYNC OPTIONS) + Smooth (Frametime Consistency) + Lowest latency possible while having the first 2 (Not the fastest) Also if you can test the new feature of RTSS (Scanline SYNC) You have a great mind and I thank you for dedicating your time to do this for us and I hope you will continue to do so.

@Battle(non)sense any chance you can do a motion delay test for a good few of the top mice? GPW, Finalmouse, Endgame gear, ZOWIE

i hope you can try compare other competitive games too like DoTA 2 for example

thx for the video!!!

Where did you manage to buy an LDAT? I've been looking to buy one

Sorry if this was covered already, but do I need to use the Overwatch frame rate limiter when I'm using Reflex+Boost or is that redundant? One or the other? Thanks!

Thanks a lot, awesome video!! What basically is not clear for me yet is the following: While having Nvidia Reflex Enabled, should the Low Latency Mode (LLM) in the Control Panel (NCP) be off as shown in the benchmarks? Would LLM on or ultra negatively affect the input lag? Or is it just not relevant anymore as soon as Reflex is on and only becomes affective when the game doesn't support Reflex?

One thing that is very interesting to consider is how much latency remains after subtracting frame draw time and the result of the SOL test (which covers scanout time, hardware latency, polling rate, ect) to see how much latency is caused by imperfection of the games input handling (careful not to confuse framecap delay with gpu draw time)

What's the current consensus for limiting FPS in games with no engine limiter? still RTSS? And has the opinion on GSYNC changed at all? Is latency better or worse with it enabled?

Hey, could you test Escape From Tarkov netcode again? They said they have changed netcode a lot, but seems the same.

Hmmm... so if I want to use an in-game frame rate limiter in order to both prevent gpu bound, as well as enable input delay consistency and frame consistency, is there any point to be using nvidia reflex since limiting FPS at a consistently sustainable value simulates a cpu bound case? At least Boost surely gives benefit, right? Or does it..? Hmm. I'm guessing not. I suppose that's why you mentioned multiple times that reflex seems to be like a very nice variable frame rate limiter, because it produces similar results to limiting frames at a consistent/reliable number, without having the frames actually limited. Am I on the right track here?

hey dude, would be awesome to see an updated look at Escape from Tarkov. they've supposedly done a lot of server modernization in the past year and the community can't decide whether it's better or worse. could use some cold hard data from the man himself

I’ve been using NULL with Reflex and my latency feels amazing. Also use a timer resolution but the one i own also is a standby list cleaner which i still don’t know is all the way safe. But on controller you feel the latency even more when it jumps than you do on kbm, atleast i do. I also cap my frames on all GPU heavy games because I don’t have a Gsync monitor (i have one on the way now)

There's a free Quake-like game on Epic, called Diabotical, that has optional multi-threaded input where an input thread runs at ~500hz, as well as giving you control over buffering (1 to 5 frames) settings, and a pretty good in-game FPS limiter. If you have time to test whether multi-threaded input is actually a boon there, and what combination of settings is "best", I would love to see what results you get.

I would love to see you review SpecialK

You sir are brilliant!!!! I love it. Liked & Subscribed! I need you to help me decide if I should get the Zowie BenQ XL2456k dyac+ 240hz or Alienware AW2521H Ulmb 360hz! No explanation needed! 😕

i do wonder about the niche case in overwatch of reflex enabled, reduce buffering off or on with low gpu usage. with high gpu usage, reduce buffering seems to cause an increase in latency when combined with reflex and i wonder if the same occurs with lower gpu usage...

The way that AMD is playing catchup here is interesting in implementation but embarrassing in practice. You get your visuals set to mud in a way AMD thinks you won't notice to not even get the same benefits as Nvidia's Reflex does at full resolution. No matter how much people dump on Nvidia and their business practices, software advances like this, DLSS, RTX, integer scaling, Gsync, hardware acceleration in productivity apps, etc, are what will keep me loyal to this brand. They are a significant value add to me.

When you are talking about smoothness, there is thing to remember. While higher framerate may reduce latency, when you are already at your monitors refresh rate going higher framerate can make it less smooth. Having framerate very uneven with your refresh rate causes it to not be smooth. For example, having 150fps on 144hz monitor is smoother than 180fps. And for more noticeable example, having 150fps on 120hz feels like stuttering to me. That is, with no sync, im not sure how it works above your refresh rate on freesync or g-sync monitors, i only know in those smoothest is to limit fps little below your refresh rate. So, if i had game that supports reflex and nvidia gpu, i would enable reflex but limit fps anyway (I assume there is no downside to enabling it). But i dont play any game that supports it and i have amd gpu currently. I dont believe that improvement of radeon anti-lag is that low at least in every case. In Quake champions i keep my fps limited to 150, and its clear to me that i get lower input lag with radeon anti-lag. On my laptop i limit it to 118 fps (for freesync 120hz) and it doesnt keep fps up there always, on it i feel huge difference. Could it be that somehow it affects input lag in Quake Champions differently than in games you test?

Love your videos, im a new at PC gaming, can you make a video showing the best NVIDIA control panel options for gaming ? Its so many options and kinda confusing.

Fantastic video

Great video, as always. I am just wondering if there is a difference when you use in-game limiter or the one in nVidia settings. I have i7 6700k and GTX 1060, while playing Apex Legends in 1080p I get around 144fps on low settings, where cpu load is 50%, and gpu load is 99%. I use the limiter from nvidia settings, set at 140 fps, but the game still feels a bit laggy, maybe it's because of 20 tick servers, I don't know. What do you guys think?

in case i missed it: what about ingame limiter PLUS reflex? will reflex get you further improvements?

So correct me if i am wrong for general usage with a suitable fps cap having nvidia reflex on + boost (just to cover all bases) and for overwatch reduce buffering enabled would be optimal. Or is it the case that reduce buffering either does nothing/ has negative effects with reflex enabled and not gpu bound

Can you check what happens if we cap the fps with RTSS to 59 and have reflex enabled, what's the behaviour of latency then?

Amazing work as always. Much appreciated 🙏🏼 ps: Would you please add a list of recommended settings in the conclusion section because it gets a bit confusing; e.g. What happens if we activate fps limiter, nvidia reflex and low latency mode at the same time? Do they block each other?

great job Battle(non)sense

Dear Battle(non)sense, did you tested fps limit with nvidia reflex or nvidia low latency? And how is the result?

Great content as always :) Just one question: throughout the video you've always talked about a "good" in-game frame limiter. Would you say the limiter in CSGO through console (fps_max x) is good? Or can you achieve even lower latency with an external limiter like rtss?

With G-Sync if I enable Reflex in Overwatch, the game auto-caps FPS to 138 (on my 144 hz monitor). Is this the Nvidia driver level limiter kicking in like it does for ULLM automatically or is it the Overwatch FPS limiter kicking in? It’s “probably” the driver level limiter I would think given its behaving just like it does for the ULLM mode+Gsync. In your prior videos you demonstrated that the in engine limiter has less latency and we know RTSS and the Driver limiter have basically the same latency. Would this mean for users who are reaching the Max refresh of their Gsync panel and hitting that automatic FPS cap that they’ll actually get worse latency with reflex ON since they’ll be running into the driver limiter? They could instead do Reduce Buffering ON + a manual cap at 140 for example, but we only know how capped + FPS limit compared to Reflex uncapped currently. It would be useful to see how Reflex + Nvidia driver level limiter / the auto FPS cap behavior on Gsync panels compares when you’re actually reaching that target. Currently there’s no way to disable this auto capping behavior so if you use another limiter you have to cap beneath the auto limiter by say 3 or 4 frames which wastes overhead. Thanks,

Nice video thank you

boost in my system also stutters when there is no mouse input and then a sudden mouse input with my rx 480 which is worse than input lag.

You aren't going to post a video about how I flew a jet into the palm tree right before you were about to unlock the black dice camo?

Great video! But what is best? 1. Ingame fps limiter on 241fps. 2.Ore activate reflex and disable ingame fps limiter. Games then run in 400 fps.

I like how scientific you are!

So how's the fps limiter in Call of Duty Cold War? It seems to fluctuate all over the place for me rather than holding a constant fps, does it also have bad input lag?

Would be awesome to see an updated look at Escape from Tarkov.

In nvidia control panel, at perform scaling on, we should use GPU or Display scaling?? and Its better to use in nvcp maximum performance or optimal?

What kind of performance differences would you see in a higher end overwatch config? 9700K/3080?

You didn't mention that boost also does variable rate shading. It's more than just simply adjusting render scale now. Also Apex Legends works fine for me on a 165hz 1440p monitor with a 5700xt so strange it didn't work for you. Did you DDU? Take this as constructive criticism cause I really do appreciate your work on this and your findings. Keep it up.

Thanks for the video , would love to see the test on valorant

Hi! I've never watched one of your video's before, but are you from germany? I started the video and the german accent insta punched me in the face xD Edit: This is not a hate commentary, just a simple question, because I live in germany

Warzone recently added a dynamic resolution feature with a target FPS setting. could you test latency with this mode on for nvidia, (but especially for) amd? Right now, in warzone, amd has no option to reduce latency than to limit fps ingame, but the problem is that in this game fps are all over the place so fps would have to be limited at a very low limit compared to avg / max fps.

Huh. Nvidia Reflex has always felt off to me but I also used a 300 fps limit in warzone. Maybe setting to unlimited will feel better.

God bless this channel, please do a test on fortnite all settings to low

Is there something to apply a percentage load limiter on the GPU instead of limiting FPS from the game?

Great comparison between both feature sets on reducing input latency. I'd be very interested to see how these CPU bound scenarios created by Reflex compare to AMD's offering after Hardware Unboxed's video on Nvidia driver overhead, affects system latency on more mid-end processors. For example, running Apex Legends on my 3060ti with Reflex enabled on my Ryzen 5 2600 causes a CPU bound scenario where I can't maintain 138fps 100% of the time. Not only does Reflex rely on my CPU, but the driver overhead from Nvidia eliminates the possibility of me being able to maintain a stable framerate. Many people are now saying that AMD is best for competitive gaming to achieve higher FPS. But based on your analysis, I would like to think that Nvidia, even with it's driver overhead issues, can still maintain a competitive advantage by offering reduced latency with Reflex despite overall lower FPS averages on CPU bound mid-range hardware.

And all my friends still call me crazy when i tell them to use in game fps cap smh at least i try. 😂

Apex Legends has some issues with it's Lag compensation, try turning it off(cl_lagcompensation 0) and go into the fiering range. you can easily hit consecutive wingman shots while draging the aim over. with Lag compensation on(cl_lagcompensation 1) tracking is the only way of hitting consecutiv shots. in game with the lag compensation off(cl_lagcompensator 0) you will get a ton of no-regs. But the lag compensation favours tracking aim over dragging/flicking. if you flick and rest your aim over the target you will hit, but if the mouse is dragged over target it will count as a miss

Do you think there is any way to implement NVIDIA reflex at a general (as opposed to per game) basis?

So should I put anti-lag on plus an FPS limiter? Also how do know what Fps to limit the game at?

Radeon Boost does not seem to be in the settings in the driver anymore. Maybe it's been removed. But Anti-lag is listed still. If you select e-sports in the driver globally or for a specific game, it enables 2 settings. Anti-lag and Image sharpening. AMD Sharpening is really very good. Not sure how to test Anti-lag now on my 6800. I guess try it out.
