Vsync or FPS limiter

[TheTallGuy]

Hi guys, so I have a little question I've been doing research about but not finding the right answer I am looking for.

 

Is it better to use an FPS lock or Vsync on a FreeSync panel? I have a 144Hz FreeSync panel and in my games, I get a higher framerate than 144FPS.

You don't need to lock your fps at all it can go over and that's fine

iinm cap the frame under 144fps is the best wae.

FPS cap is always better than VSync if you want to stay in the FreeSync range because VSync introduces quite a bit of input lag. 

 

That said, FPS cap in the NVIDIA and AMD driver software introduces the same amount of input lag as a VSync for some reason, best to avoid these. 

 

Always use in-game FPS limiter if available. If not, use RivaTuner instead.

V-Sync Triple Buffered is always better than FPS Capping specially if you want to keep using FreeSync.

 

FPS cappers depends on game engines and usually cause Tearing, V-Sync Triple Buffered will render ahead of time and always have the frames ready to display eliminating input lag issues.

 

If you are playing a highly competitive game such as CS:GO the best way around is use nVidia FastSync instead (if you have nVidia), this will eliminate FreeSync however keep game smooth without tearing much the same way, it's only catch is that you always have to maintain your fps above the 144hz refresh rate.

ive personally found that turning on Vsync over FPS limiting is a much better option, especially if there is screen tearing. However with a freesync panel and an RX580 according to your profile,  you should be using Freesync over both FPS limitations and Vsync for the bes experience.

AFAIK you do, to prevent the monitor from going out of the FreeSync range.

From what I've read it's best to lock your FPS around 3FPS under the upper FreeSync range to get the best results.

V-sync is the best.

There is absolutely no need to higher framerate than 144FPS.

I compared Vsync vs fps cap at 75 fps in World of Tanks and Monster Hunter World.

 

I set the Vsync triple buffered both in Nvidia control panel and in-game setting.

 

What I found is the triple buffered Vsync serve me smoother frames than fps capping like @Princess Cadence said.

FreeSync once enable it still won't stop your FPS from going over it's range of effectiveness, that means you still gotta limit to stay within the range somehow if your GPU is capable of exceeding it.

I can assure it isn't, from extensive testing both with a Vega 56 and the GTX 1080 Ti on a 2560x1080p 75hz FreeSync monitor I have come to the conclusion that FPS Cappers specially those built in games will continue to provoke Tearing (extremely noticeable with FreeSync disable, less noticeable but still present with FreeSync enable).

 

Tested games for example: Assassins Creed Origins and The Witcher 3, FPS capper for 60fps which is within Freesync range showed persisting tearing specially when caused on purpose as in turning mice really fast around while running.

 

All problems were solved when switched to V-Sync Triple Buffered at the native refresh rate of 75hz which is still within Freesync range, V-Sync Triple buffered ALONE already eliminated all possible Tearing when sustained at 75hz which was the case of the fast enough GTX 1080 Ti to where FreeSync becomes redundant, on the Vega 56 however any dips from the 75hz/75fps margin would not cause any tearing thanks to FreeSync.

 

Forcing dips by super-sampling with the 1080 Ti showed same behavior as the V56, while it's on 75hz there's no tearing, random dips as low as 32fps( within Freesync Range) also did not introduce Tearing, FPS Capper would tear still even when it maintained the 60fps solid.

 

"Input Lag" the biggest villain so many people parrot constantly as something that turns V-Sync useless was not an issue whatsoever, responsiveness between V-Sync Triple Buffered vs no sync what so ever at least on these slower paced games was to me imperceptible.

V-sync is usually okay (That's what I use on my 75hz panel) and it is built into almost every game for quick and easy use. Fps limiters have their place if you need to limit the fps due to hardware reasons (Such as heat, if you are wanting the max fps output that may be above the monitors rate, however you don't want it so high it will cook the GPU. Think competitive FPS shooters)

I use 144Hz monitor, but I prefer my gaming experience with triple buffer Vsync enabled and relatively lower FPS as long as it still above 60 FPS rather than to have 120-144 FPS along with some screen tearings by disabling Vsync, because lower FPS with Vsync enabled gives smoother frames than disabling it while having really high FPS. And most of the time my average FPS with Vsync is enabled are at 75-115 FPS.

 

OP, don't cap the FPS, just let the frames freely synced at whatever numbers it kicks in..

[Constantin]

I play all my games at 75 FPS (monitor at 75Hz) with V-Sync

It is just perfect
