What is V-SYNC anyway?

#shorts #vsync #pcgaming
At some point, almost every gamer on the planet has thought to themselves, “what the hell is Vsync?”
Depending on the game there can be loads of different graphical settings. But Vsync is one that’s always there.
But what the hell does it actually do and should you have yours on or off?

[@satoruriolu6132]

Its a surprise he didn't mention another downside of V-sync, a small delay between input and action. Since V-Sync attempts to synchronize the frames so they don't appear split, it does so by waiting a very small amount of time to display a correct, tear-less image, and that delay can be felt for fast games. If you want responsiveness, for competitive games, turn it off. Better to have a visual annoyance than be a few frames in the past, screwing up your inputs

[@vascop3642]

​@@linuslooser6917If your're using a free - sync monitor you whould turn off v - sync in game setting and turn on free - sync in the monitor setting. That doesn’t increase delay because is the monitor that follows the GPUAS frame rate. If your GPU makes more fps than your monitor's Hz then cap your fps

[@zwingler]

Vsynch can also be super practical if the game either has FPS Uncapped limit or 60 FPS. If you have a 120hz monitor you can enable v-sync to lock it to 120 fps without external tools and such.

[@ACE112ACE112]

locked fps gived worse input lag.

[@CrocoDylianVT]

V-sync is honestly criminally underrated, the input lag doesn't even matter if you enable AMD Anti-Lag/Nvidia Reflex, also the "unnecessary cap" is very necessary since it'll cap the FPS to your monitor's refresh rate, since tearing occurs when getting more frames than your monitor can have, you get rid of tearing, akd the real unnecessary is that framerate and you won't even see and just stresses your PC unnecesarily, plus, limiting the framerate to the max your monitor offers also gives you performance headroom to crank up settings a bit more

[@dtpg5713]

Wrong, if you have unlimited fps your fps will drop on high graphics.

[@BerserkerErik]

​@@dtpg5713 I dont understand how he has said anything wrong here.

[@dtpg5713]

​​@@BerserkerErik I am saying that if he can have a number of fps with Vsync, he can have it without Vsync or even more fps, also it is good to have a high framerate even above your monitor's refresh rate. And imagine spending thousands of dollars on a gaming setup and use Vsync.

[@deadtodoom6592]

@@dtpg5713dude… the point of V-Sync is so that when your running a 65 htz refresh rate on your monitor and a 3070 Ti that can get you over 140 constant fps they practically link and ur gpu caps at the refresh rate of your monitor to reduce unnecesary stress on the gpu. Which in turn results in less screen tearing and a smoother experience.

[@crapyguy1234]

Exactly, just to let you all know. When you enable vsync at a graphics API level, you actually tell the graphics drivers to stall the render thread when presenting a frame. This allows the thread to not waste extra resources on the cpu and gpu, opening more cycles for other tasks to be done. If the game is heavily physics based, this could be super helpful depending on how much of it is done on the CPU. Sorry got a little 🤓 face there.

[@rachitbhatt40000]

I've been playing for years keeping this setting ON. Recently, I've played many games switching it OFF my experience was terrible in every game. Seems like my eyes can easily track these details now.

So little tip just get a gsync compatible monitor. It has the same effect as vsync but with no delay added.

​@@user-xj7os2wi3d Enabling Vsync will definately reduce with screen tearing in case you're still getting it it means you must have set your displays refresh rate to less than its Max limit. Like you have a 120hz but your display is set to 100hz or something

[@ThatJay283]

if you still have tearing then you don't have gsync/freesync/etc enabled

[@diysai]

I have a freesync monitor, so I don't use vsync, but capping fps below 60 really helps reduce power and heat. Most single-player titles don't need more than 60fps.

[@POLARIUN-lb6je]

[@JayUchiha17]

I literally get screen tearing in every single game I play. I've tried everything by trial and error on a 120hz gsync tv and regular 60hz monitor. I find it interesting that no one can give a simple tutorial how to completey remove screen tearing without using vsync. And I'm beginning to realize they either ignore the stuttering or weird inconsistent visual flow of frames and input latency that always comes when vsync is off. I'm yet to get a consistent gameplay like a ps5 with gsync off or be shown how to do so.

[@JLittles-jzx4]

was in the same boat, i used rtss to cap my frames with gsync on, in game turn off vsync and set to unlimited frames, ex. i set my refresh rate to 144hz, then open up rtss and cap frames to 140fps , then in game turn vsync off and set fps cap to unlimited, gsync has to be on for this to work, and i always cap my frames 4 below my refresh rate, i get smooth no screen tearing and no input lag from key/controller, hope it helps

[@JayUchiha17]

@JLittles-jzx4 You are correct. I actually figured it out mostly. You will always need vsync but never turn it on via in-game settings, only through your PC's Nvidia control panel of that specific game. Everything you said about RTSS is also correct, and it does work. I also finally ordered in my books the perfect gaming monitor. The LG UltraGear QHD IPS 1ms HDR 400, NVIDIA G-SYNC, and AMD FreeSync, 165Hz. So there isn't any way my games shouldn't run smooth now 😁🙏🏾

[@carvideos5276]

Authors of new games make shit engines and they dont care about g-sync or screen tearing

[@brunch.]

you cant just post a tutorial to youtube about 5 simple steps to remove screen tearing. It requires technology built into your setup. Anyways you are certainly wrong about needing Vsync. I suspect that maybe your graphics card is much faster than your CPU, or you are using a low hz monitor. When I play games at 120+ fps on a 165hz monitor and Vsync disabled I have no issues with screen tearing.

[@dc-vw4qm]

screen tearing happens cause frame TIMING variates, not frame rate, you need to get your games running at a consistent FPS, not a high instable one to get rid of screen tearing

[@DsGBiohazard]

Without vsync, you are getting screen tears. Without vsync, you're getting either so much tearing you can't notice, or just barely enough so there's one big consistent line on your screen. Turn vsync on. Try adaptive vsync in the nvidia control panel, it disables vsync if you fall below your refresh rate.

[@ayanmukherjee2170]

it depends on the game, in a game like Rdr2 where the chances you’re gonna get more FPS than your refresh rate is very low, so you might as well turn it off and get more frames. In most games tho, I agree

[@sebastianaliandkulche]

[@LautaroQ2812]

V-sync, today, is good enough to avoid screen tearing AND cap frames for a consistency on frame times. If you want to avoid screen tearing and having v sync off, you must produce double the frames of your refresh rate minimum consistently or more (for example, 60hz = 120fps or more at all times). Only then you will feel your game buttery smooth and with no screen tear. Otherwise you will suffer from either stuttering or screen tearing.

[@timalb]

I find G-Sync or Freesync a better alternative, not only you get the same tearless picture but it also doesn't add a delay. However g-sync seem to not be working properly with some games that have internal FPS cap, like games by FROMSOFTWARE, which seem to be breaking the effect of G-sync somehow, and only enabling V-Sync gets it back together

Most big games user settings have a cap frame rate you can change. I’ve changed sensitivity caps and everything with user settings. Tend to set it to my monitors refresh rate

[@namgunaucao9771]

Turning on vsync helps me reduce stuttering because cpu is not 100% overloaded especially when driving at high speed in gta v, far cry 4....cpu loads almost 100% and stuttering occurs. Turning on vsync helps to reduce frame tearing, reduce the work of cpu, gpu, ram.... and it also reduces temperature, reduces stuttering. I always lock 3A games at 60fps, and shooters like csgo at 144fps according to the screen.

[@MegaGamer22]

WARNING: Leaving VSYNC off will make the game run at the highest framerate possible (if the frame limit is unlimited), which will make the game use 100% of the CPU and GPU. If you don't want to fry your GPU, turn VSYNC on unless the game already has a frame limiter (tearing will still occur).

[@unknownbeck]

Very helpful tx😊

[@light.5562]

V sync matches and caps your fps at your refresh rate of your monitor. Saved you a minute.

Locking frames is actually great for fps stability but not for latency. Vsync reduces my studders and screen tearing but like he aaid i dont use it for games like league due to slight input delay

[@L4ZYJ]

still surprised that still, no one mentions here in the comment that using vsync is only effective (to avoid latency) when used with gsync and cap the frame rate 1-2 fps below your monitor rated hz capacity.

[@erfanjavidhoseini]

The best option is choose v-sync on fast in the Nvidia control panel for guys who want high FPS while having low monitor hertz, game will run at highest FPS but monitors have not any screen tearing because its getting the frame that your monitor can afford, im suggest this for FPS games if you have a 60hz monitor and game is getting so more fps

[@dafyyyyyy]

Turning vsync on or capping fps to 60/75 drastically reduces heat of the gpu and noise of the fans. The gpu will not use 100% usage. Example. I have a i5 11400 3060 12gb Resident evil 2 on ultra settings maxed out everything and UNCAPPED is smooth and responsive however the gpu temp reaches 77c amd the fans are running extra loud. Turning it off reduced the temp by a whole 16c and noise drastically reduced but at the cost of minimal imput lag. It helps massively with keeping longevity on your components and not frying them.

[@ThatJay283]

"unnecessarily cap your fps" - this capping of fps is actually a good thing. if you're getting 83 fps on a 60 hz monitor, those extra frames are just wasted, and the cpu also has less time to do things. uncapped is only really useful for benchmarking, and possibly slightly lower latency. your pc will also run alot quieter with vsync on. even if your game is running at ~2000fps on a 144hz monitor, your monitor is still running at exactly 144fps

[@AsKnownAsLucy]

Vsync should be used together with freesync/gsync. Vsync works like a frametime compensator in the Freesync range. Lock ur fps at 3p below your monitors refresh rate. Voila! You have no tearing, no stuttering and no added input delay from vsync

[@rokaiyakhan395]

I knew what it does but my friend never agreed

[@reviewforthetube6485]

Screen tearing is hard to come across now. I leave things uncapped now and no v sync and barely ever see tearing. It's not worth capping or sync for me. When I'm getting much lower frametime and latency leaving it uncapped.

Is double buffering the same thing as v sync or does it function differently?

[@gaddeath]

It’s a type of v-sync. There’s double buffering and triple buffering. Might wanna research because I know I’m not 100% confident but double buffering steps down the frame rate into even multiples of your refresh rate. Example if you play on 60Hz and you can’t hit 60 FPS, the game drops down to 30 FPS. Triple buffering is supposed to alleviate this issue so it’s more preferred than double buffering.

[@Hostile2430]

I keep vsync on because 60 FPS is good enough for me and i often get bottleneck at unlocked frame rate. There is little difference between Playing at 60 and say 70-80 i would rather sacrifice few frames and increase some graphical settings to make game look pretty. But for competitive shooters like CS2 its best to turn it off

[@darkblader06]

Uncapping fps in recent years can cause some less than desirable hardware errors do to poor optimization.

[@remipennel121]

ALSO, and most NOTABLY for me, V-sync adds input delay and, in some games where the implementation isn’t great, it can make the experience feel very sluggish
