How to avoid tearing ?

[YouGroove]

I have simple walls, and i see visible tearing when not moving and rotating camera.

I have in App.lua :

function App:Loop  ... 

   --Refresh the screen
   self.context:Sync(true)
....

 

Is there another way ?

you mean some Walls flip dark and then it draws the normal Texture when you turn in fp view?

[YouGroove]

No, it's screen tearing.

I don't know why but print screen can't capture the effect ?? So i reproduced it using Gimp in attached image.

Does anyone had that effect ? And hsould not sync function avoid that ?

The easiest way I know of to avoid screen tear is to enable v-sync

 

edit: My bad--saw that you have v-sync enabled. That SHOULD do the trick...

whats your framerate?

 

@micheal

 

yougroove have set in his startpost sync to true so vsync should be activated. how this function works and if it give us double or trible buffering i dont know, but yougrooves screen looks like normal vsync off artifacts. do you have more context create or some context functions that maybe influence the vsync?

If you are calling Sync(true) no screen tearing should occur.

It is not Lua code i posted above ?

No, your code looks correct, which is why I don't understand how that could happen. Unless your graphics driver has some setting that forces vsync off.
