Tearing without Vsync but only 60fps - GTX 780 AMP

[Nic]

No matter if I select Vsync or not I always "only" have 60fps. Also I get tearing even though I don't have more than 60fps (measured with FRAPS).
I am using the nVidia GTX 780 GPU (as the Zotac AMP version).

Factorio limits to "only" 60 FPS as it only does 60 UPS (updates per second).
Because the game state is only able to change 60 times a second, there is no point drawing it to the screen more frequently than this.

Are you getting tearing with Vsync enabled? If you are only getting it with Vsync disabled then that is to be expected.

Yup, Factorio's maximum framerate is 60FPS, because of the 60 Updates per second system used in the "Step Lock" used for Procedural Syncronisation.

Tearing is a very common symptom of any system not using VSync, why anyone would not have VSync turned on (or even Vsync support in other games) is beyond me.

It's just one of those things I have an opinion about. VSync, Always on, no exceptions, I'd rather have a decreased framerate due to framelock when it can't quite get up to 60 FPS than end up with tearing. (So 30 instead of 58 if it can't quite keep up with 60, as an example.)

Hello, unless you get tearing with vsync on, it is not a bug, as Factorio can't have more than 60 fps.

It could theoretically have more (like 120), if we extrapolated the player movement in the inter-frames, so the movement could feel smoother, but it is not our priority now, as 60fps is enough for most people.

With Vsync on there is no tearing.
I only wondered why FRAPS says I have 60fps constantly but get tearing anyways - shouldn't there be no tearing if there are "only" 60fps?

Vsync not only limits FPS but also makes sure that flipping from one image to the next happens during vblank and not when one image is already halfway displayed, no matter how often that happens per second.

Never thought of that, thank you
