This Setting is Ruining Your PC - Gsync/Freesync & FPS Caps

Bruh I’m no math expert 😂

Thia made my keyboard very sticky after watching.....full nerdgasm...

I really enjoy the content of your videos, but please synchronize the audio, cause it's very annoying to keep up.

Can you test fortnite in chapter 5. I get crazy fps drops. And so is a lot of the Fortnite community and we can’t find a fix

Can you show where did you find the 0,3ms required to gsync? Is the first time I ear this.

in my case running a 4080 with a 13700k I can tell you that the best response time in FPS (smootheness) is with Gsync + Vsync + limit FPS rate in NVCP, smooth and stable all the time, I have tested this in different FPS, but mainly in COD (which is now for having some mouse lag becuase of bad optimization) and Hunt, is not perfect (specially with the flickerings in COD) but is super smooth

so for simplicity you can just use the in-game cap? seems like it had negligible difference than the vsync combos...

I'm somewhat confused.
With GSync + VSync + Reflex (with Nvidiacard) do I need to do the 0.3ms ingame cap as well, or is that only without Reflex?
And what do I do for games that don't support Reflex OR have an ingame limiter? Thanks!
PS: How would your recommendations differ if usage of the Special K tool was factored in?

What about 170hz on a nvidia card? 3060 12gb

Do you have allergies? Sounds like you're very nasal

I have 200hz monitor. I use gsync+vsync+ultra low latency. In games it caps my fps to 200fps. Is that ok, or is it adding latency because of vsync?

bruh Vsync literly caps it to 60 FPS so your tests are all pointless cause of the massive latensy of 60Hz

Please investigate freesync, could use some solid information if its exactly like Gsync and what the differences are. Yes we can also enable vsync in the driver with freesync.

This is how I win

How about in Modern Warfare 3? which one is better? Thank you.

Whats best for warzone/mw3?

thanks

The critical number for human time perception is about 42 ms

Which make it easy to remember. YMMV, of course, but our senses are generally logarithmic.
So '45' feels subjectively much worse compared to 42, then say 41 does to 28.

To 'show this up' in a metric that will seem to match how it feels, take the latency, divide it by 42ms, and then take the base-10 logarithm of that, and multiply the result by 10 to get 'perceptual decibels'.

Numbers above 0 are 'bad', numbers below are better, and you probably won't notice a difference of just 1 decibal or so, in back to back tests.

Side by side, you might perceive a difference around 0.3 dB. But with a longer delay, say if you walk away, someone changes the setting, and you walk back? Yeah, it would have to be at least +3 dB worse for you to notice that it had happened.

But note that all numbers under 0 will 'feel ok', but everything above zero will 'feel bad'. A further improvement below zero buys you much less than even a small improvement towards zero, but crossing under zero is what you will appreciate most of all. Lower isn't necessarily much better, if the figure is negative anyway, it's just a nit-pick.

human senses are wierd that way.

Is your personal number 42? Here's how you test: Get a microcontroller (arduino) and have it blink an LED on and off for you. (or, if you can afford it, or have it laying around, use a 'function generator' in 'N-cycle pulse' mode.
Every time you tell it to, you want it to turn on, wait the delay you're testing, then turn off, wait that same delay, then turn on, one last wait of the same delay, and then off again.

This is two rapid blinks.

This is the 'time' equivalent of the 'two black bars on a white background' visual (spatial) resolution test, BTW.

If you perceive the two blinks as two blinks, then decrease the time you're testing.

If it seems to just be one blink, and not two, increase it again.

This way you can zero in on your own personal time resolution threshold. YMMV, but at a setting of 41 ms, I saw just one blink, and at 42 ms, I saw two blinks, which I could just tell was a super-fast double-flash.

So, the result is that 42 ms is the resolution that I can 'just tell apart', and that's why we divide by it before taking the logarithm.
Then under zero means less - which is a blur, overzero means clearly perceptably lagged. Time it by ten, because it just so happens to work out that gives you the significant figures that matter.

Using Gsynx + Vsync + ULLM + Reflex BOOST and its good

So if I’m playing Overwatch 2. Should I cap the refresh rate in game to my monitor while using g-sync+v-sync and reflex? Or should I put a cap below the refresh rate instead? Some people say you should cap 4 fps below the the max refresh rate for lowest latency and no screen tearing.

Where do you do these settings?

good grief, I'm just going to stick to single player games lol

Try Fast Sync, too. It's superior to V-Sync. If you want V-Sync to eliminate tearing always use Fast Sync (or Enhanced Sync for AMD). You still need an (ingame) FPS cap to have a butter smooth picture in your displays range like 115-117FPS for 120hz on FastSync and 119FPS cap on V-Sync to have LOWER INPUT lag, otherwise you end up having double latency in Vsync, so all in all you could just disable V-Sync or FastSync altogether and stay at the frame limit. Example: G-Synced Baldurs Gate 3 @4K on 120hz TV - Main Menu latency
FastSync (~19.5ms@187FPS) (~13.5ms@120FPS inG-capped)
No V-Sync (~19.5ms@188FPS) (~11.2ms@176FPS inG-capped) (~13ms@120FPS inG-capped)
V-Sync (32ms@120FPS non-capped+inG-capped) (~13.5ms@119FPS inG-capped)

System: 13600K / 4090 @60% Power Target / 4400 D4 / LG CX

I don't see any benefit in having V-Sync on/off if you use the drivers or ingames FPS limiter, without the limiter the Input Latency is nuts.

So when you turn on V Sync in Nvidia drivers plus GSync for window and full screen modes you are in G Sync + V Sync territory or you need V sync turned on in games too for it?

Radeon software does allow you use both settings together, this had been an option for years ! I don’t think many people know about it though I always tune my settings this way whenever make a system

SO WHAT SHOULD I OFF??

here are the proper settings for Nvidia control panel:

Gsync = ON
Vsync = ON
Ultra Low Latency Mode = ON

proper settings in game:

Vsync = OFF
Frame cap = OFF
Reflex (if supported) = ON

Gsync + Vsync MUST be enabled for Gsync to actually work, and you do NOT need a frame cap because Ultra Low Latency Mode caps your frames to your max refresh already, and in Reflex supported games Reflex will automatically override Ultra Low Latency Mode.

that's it. that's all you need to worry about. anyone saying otherwise is misinformed.

I’m confused so what is the best combination for amd users? Specifically the 7900xtx? On a 4k 120hz free sync premium Pro Display

your formula of +1ms means 360hz monitor = 260fps max and 540hz monitor = 350fps max

Should i run settings like this when i play league of legends, fornite, valorant, and some open world mmo?

Thanks for the video, insightful.

I wonder what result you would get with just reflex on versus the others.

i guess people never seen Battle(non)sesne videos on all this, where he goes way more in depth about the topic and explain how this all works.

i always cap my fps from nvidia to my monitor rate. yes it is 60. and i am ok with it when i use reflex and no vsync. the response time is very good for me at 4k gaming.

My setup for Competitive: Uncap everything, turn on reflex, hope you have enough skill to beat aim bots and controller hacks. Singleplayer: cap it at 100fps ultra everything.

I'll give the gysnc vsync ONE try in CS2 and if that doesn't work I'll throw in the hat.

Most ingame frame limiters are crap, they never limit the frame to what i want and never steady frametimes!
Rivatuner all the way

The second i enable Gsync + Vsync my mouse and input feels a lot more sluggish. Vsync adds some weird input delay or similar, just moving mouse left and right makes it seems slower and less responsive. How do you explain that ?. Also if game fps cap doesnt work what do you recommend RTSS??
EDIT: Also is your Vsync on FAST or ON in Nvidia CP ?

All you Kids need to stop pretending that you're super latency-sensitive Pro Gamers just because you got 2 1/2 Fortnite W's in 2021. You're not. In Fact you probably only recently moved away from a Console or a 60Hz hand-me-down Monitor. Personally, i'm gonna use the Setting that has the best Motion Clarity and the least Image Tearing. A couple Milliseconds of Input Lag more are not gonna make a Difference. The Things that allow me to top Scoreboards consistantly have nothing to do with my admittedly amazing Setup. And yes, i'm arrogant. Get mad. 😎

Install rivatuner and all you have to do is check the graph..if the graph is flat then thats your best option. If the graph spikes then don't cap the fps from in game fps cap. Cap it on rivatuner. This video doesn't show that much. No 1% lows which is one of the most important thing in this. Good effort but you're quite far off.


For people reading this...G-sync + vsync (on nvidia cp) + cap fps 3 or 4 below your monitor refresh rate. You're set.

Where’s the 1% lows graph? I’m pretty sure those would be important considering the topic.

I have to use v sync or a fps cap because screen tearing sucks ass and I'm not playing like that

PLEASE INVESTIGATE IT, I have messed with it myself and it feels nice as hell, but I don't have the technology to do it.

GREAT topic .. looking forward to part 2 -6900xt/5800x3D user

I was perfectly comfortable building my first PC one month ago and installing windows. Adjusting all the software crap afterwards is when the headache began 😂

So always LLM off? There's an On option too.

im so good that the extra latency is my handicap for other players.

I have a bit different problem on my ViewSonic XG2431 (240 Hz). I'm not reaching 240 fps in Finals (pun intended) on my 1080 Ti + 5800x3d. In practice range I can go well over that number but in normal game it's obviously lower. Anyways, everything over 240 = choppy, laggy (no cap, no gsync/freesync, reflex on/off). The problem is I have to have FPS and HZ completely in sync. For that I need to use RTSS since in-game config cap doesn't have a stable frame time, as in most games, that's just fact. So I need to change my hz in Windows to 144 and cap to 144 fps via RTSS for smoothest experience since I can hit those number 95% of time, if I leave 240 hz in Windows and cap to 144, again it's choppy and laggy. Everything between is also choppy. I understand it's always better to have these values same, i.e. stable 240 fps on 240 hz monitor but I'm seeing a lot of people, probably most of them to run like 100-200 fps on 144/240hz monitor with no gsync/vsync and going just fine. I have the latest drivers of course. Anyone know what could be behind this? Can it be faulty monitor? I'm desperate now because I tried so many things and nothing has helped me.
