Tearing on games under 60fps?

[SkeeterUK]

Just wondering if anyone knew of why tearing happens when your fps is under 60 i.e 30fps.

A few games i play has fps like 40-50-60 fps and i get tearing. Sometimes i think even 30fps or lower.

Could be just the game i suppose. I used to use vsync and then d3doverider and just stopped bothering as cba with the fps loss or lag however small. I have had to put up with tearing even tho i really hate it and it can get pretty bad.

Got a modest pc still with a dell st2410 monitor.

So just wondering if anyone else has tearing under 60fps and if you just live with it or found a fix without using vsync as vsync works but really why is it tearing under 60fps as thats what vsync should really just work for.

I have to battle with tearing and performance when I record gaming videos because it can ruin a good bit of gameplay (keeps the picture stable on playback & lessens motion sickness for me). Everytime the tearing has been solved simply by using ingame Vsync and getting used to the slower response of moving about whilst getting a perfect movie from it. I've tried my GPUs control panel to override and set Sync on with triple buffering and that doesn't work as well at all. Utilities like Afterburner just limit the framerate to a set amount and didn't work with Skyrim in my experience.

Edit: You can also get tearing from overclocking too much so try from default clocks.

Whenever I use v-sync, I get really bad mouse lag. I've just learnt to deal with it tbh

Yeah just deal with it, i spend loads of dosh trying to solve it with different cards, cables, monitors etc but never did, only way i think i could fix it now would be to replace my monitors with displayport monitors and have a triple displayport gpu..

v-sync works most of the time but yeah it can make some games have mouse lag, well what feels like it anyway

Which games are you experiencing this on?

I always use the ingame V-sync to reduce or stop tearing, but never had input lag issues when using it. Well, Only for Crysis 2 which was really bad lag but turned out it was an issue with the game and there is a simple fix for that.

Only game I have witch screen tear bad is metro 2033 that game is a joke. Everything else I use vsync and get no input lag at all.
With metro 2033 I cant even use vsync, while the game is good, its not very enjoyable because of this.

Screen tearing will always occur if vsync is disabled. The fps makes no difference whether it's 30 or 130.

Extreme mouse lag under vsync is a fault of the game not the vsync functionality.

Tearing is caused by non-synchronous signal (refresh rate) between the video card and the monitor. A line is created where the screen displays a frame buffer before the old own is removed. Enabling Vsync ensures the old frame is removed before displaying new. Although this corrects the problem, you may experience input lag (which is what you are experiencing) or screen judders as the monitors refresh rate will be expecting frame that doesn't come.

I wrote a small article about it :
