I've enabled it in every game I've played since the early 2000s, purely because screen tearing looks really awful and disabling vsync does absolutely nothing to increase my frame-rates.

 

I've been to several LAN parties recently and many of the gamers there swear by keeping vsync off - and they somehow don't notice the screen tearing when it's very visible to me on their screens. They also suggest turning vsync off if someone gets a lower-than-60 frame-rate, which again, makes no sense to me. Disabling it has never increased my frame-rate in such circumstances.

 

Maybe vsync mattered more in the CRT days? (I can't remember, it's been almost 10 years since I had a CRT monitor)

 

Thoughts?

Well, IMO it varies from game to game,  in hitman:absolution it brings my fairly old system to a crawl, in fifa 2013 the game is unplayable from the stuttering ( and mind you my system is way above the recommended requirements. A contrary example would be DmC ( Devil May Cry) it apparently does nothing to performance, the same applies to games using unreal engine.

I keep it off because it's a double-edged sword. It can haunt you at the worst possible, the most intense (and important) moment of the game.

 

Enabling triple-buffering solves the tearing problem much better imho.

It was definitely a CRT thing. I never turn it on anymore unless the game sets it as the default

I agree, the performance hit seems to vary by game, and probably by hardware. In the end its one of those preferential things--some people are ok with low quality stereos or cheap food for the trade off in money. The same applies for gaming. That being said, screen tearing really annoys me too!

If your PC consistently outputs 60+ and the game isn't some online twitch fest you could leave it on. There are also some games that are not graphically demanding (or just a game menu) but lack a frame limiter and the GPU ends up rendering hundreds of fps and overheating in the process (eg. Starcraft II's main menu at launch). Outside of these examples, I keep it off because I don't really notice tearing. Probably got used to it after using weak GPUs in the past with which vsync was not feasible.

Every time I've turned it on the mouse feels so sluggish (I only play FPS games), so I keep it off. I've never really had much problem with tearing either.

If you have an Nvidia card you can enable adaptive v-sync, then leave it off in game. I've found that to be an acceptable compromise. More recently I usually just do whatever the Nvidia tuner tells me to do.  :laugh:

All depends on the game itself and just how bad the tearing is, so I would say it varies from game to game.

IIRC, the Unreal Engine tears like a mofo, so I tend to enable it for all Unreal based games.

I know for example on Bioshock Infinite I definitely enabled it.

 

For a game like BF3 MP, I disable it, so I can get more than 60 FPS to have a absolutely smooth experience. The more frames the merrier I have always believed with MP. I know people say your eye cannot process more, but I believe it also comes down to processing what is happening in game, more than just visuals, so I disable it for most MP games.

 

I too also never enable it if I am not getting a constant 60 FPS prior to enabling it. All you are doing then is forcing the game to run at a frame rate you are not able to achieve, so it is definitely skipping lots of frames to make up for the fact.

 

So yeah, it all really depends on the game and it varies. I do not have a set approach. I adjust accordingly to each game. I am a bit OCD like that though, usually with PC gaming, I take a good 15-30 minutes to find my optimal graphic settings. I will literally enable each one one at a time, either fire up an app like FRAPS or EVGA Precision and make note of the frame rate I get, and/or use the built in benchmarking app. So yeah, I tend to be a little OCD with getting the optimal frame rate versus optimal visuals.

If you can get 60+ FPS constantly (on a 60Hz Monitor), turn it on.

 

Otherwise, with v-sync you will not see 55FPS, it will dip your FPS straight to 30.

I disabled it in Bioshock: Infinite for that reason - game plays fine without it, with it, lots of time when things were laggy to to v-sync going to 30.

Are you sure? I've never witnessed a game that overs between 55-65 FPS jump between 60 FPS and 30 FPS constantly.

I've always kept it on.  Never had a reason not to.  Will have to try shutting it off and see if it changes anything.

This guy did an excellent job explaining how Vsync works.

I have never witnessed my frame-rate half if I dip below 60 FPS by even 1 frame when I have vsync enabled. It just doesn't happen. Not on my systems, at least.

Oh, I thought Vsync was one of those dials on an old TV set that you had to turn so the picture wouldn't keep rolling. I keep it turned on.
