Why do some games experience more Screen Tearing?

[Trava]

I've been playing a lot of games recently, going through my list to complete what i purchased through each sale, and for some reason the more games ive played out of the few i often do, some games have ungodly amounts of screen tearing, to the point i have to enable VSYNC or it feels like my game is stuttering.

Take note, i lock every demanding game i play at max that would normally fluctuate fps between 70-120 to 60fps because it creates an overall smoother experience than fps fluctuation stuttering.

Heres an example of a game that runs amazingly, Sleeping Dogs, locked at 60fps on my 120hz BenQ (or any monitor) i max out the graphics, and there's no tearing atall with vsync off (There obviously is its just so unnoticeable and so small and out the way it never seems to bother me.

However, a handful of games i played, Mirrors Edge, Crysis 2, Skyrim & Saints Row 4 all have ungodly amounts of screen tearing, to the point i get seperate tears and the screen stutters at times (unrelated to the fps) i worried if maybe it was my fault so i locked vsync at 60hz just to be safe and low and behold, the stuttering feel was gone, i played all through mirrors edge and Crysis 2 without a single problem (all be it the dreaded mouse lag of VSYNC), i played through Saints Row 4 like it too and it was a lot better.

However some games that i play, Tomb Raider, Sleeping Dogs, Doom 3, Bioshock Infinite have just a little bit that it never looks like its stuttering.

I've been in the planning of getting a GSYNC for a while, but with recent news of the driver i have held off until further news, but surely if games are going to tear they would all do it the same? Im rather uneducated in this field as its only recently ive started playing more demanding games and locking them at a lower fps than exactly 120.

G-Sync is fine, but you'll need a monitor that supports it, as well as a supported NVIDIA GPU.

I know, i meant getting one, just wondered why tearing was so different between games,.

Cause it tears differently at various FPS. Plus it depends on the display too.
But given as how u were trying out games all on the same screen, yea mostly cause of the FPS fluctuations and such. That is why tearing occurs.

Did u try turning VSync off in-game, then exit game and enable Adaptive VSync within NVIDIA Control Panel. Try that.

But it happens mostly when locking the fps to 60 @ 120, its what i do for most games.

Some games tear so much like L4D2, borderlands 2 and mirrors edge that i gotta keep vsync on if i lock them to 60fps because of the tearing makes it seem to randomly stutter (im on a 120hz monitor) but i can run l4d2 at 120fps so its no ,problem, sti,ll notice tearing but its just one consistent line and doesnt make the scrrreen stutter.

It is all about optimization in the game and game engine itself along with how well said games work with certain graphics cards/drivers.

I have a 144hz Monitor that I keep at 120hz and then fps limit games to 90 fps. I can play with v-sync off and it looks amazing since I am not running up against any of the hardware or software limits. But there are still some games that have terrible optimization and will tear even with vsync on or with the best graphics cards known to man just because they were badly coded or ported from a console and such.

Let's say a game with crappy code somehow thinks your computer has an insanely high refresh or fps limit and then tries to go for that bad line of code, you get tearing regardless of vsync and such as it is trying to put out a higher refresh or fps than your monitor can handle... Your computer and graphics card are still thinking everything is good and at 60fps when it is over 200fps or such. Basically just bad coding and some miscommunication between hardware and software. I believe the sims 3 had a noted problem with that where it would overheat peoples GPU and cause it to crash when it ran at over 1000fps in certain scenarios even with vsync on.

As for g-sync, wait a bit longer till either the middle or end of this year as there are going to be some actual affordable monitors coming out with it.

Ah i see, that would explain some oddities in which vsync and some games work.

For example, typically in both Darksiders 2 and Deus Ex, i noted going past certain points would cause a game stutter, however with VSync on these stutters were gone! So it explains why externally locking the fps to 60 with a program ,like RTSS compared to vsyncing it wont cause the same syncronization, and in turn also have the same effect in screen tearing.

Some games locked at 60 are fine, i was testing it to see what games did what, Deus Ex Human Revolution,,locked at 60 had literally no tearing ever, and was perfectly fine. However, Darksiders 2, L4D2 and Borderlands all had excessive tearing, usually in exactly the same places aswell, L4D2 not so much bad as the tearing would make the screen appear to stutter or judder every once in a while, while mirrors edge and borderlands 2, and in turn alan wake all locked at 60fps would still tear excessively no matter what!

I'll give a shot at your advice locking some games to 90 hopefully that is a good mix of smoothness and reduced tearing.
