Sync to VBL in the editor

Hi to all,

I am trying to get the sync to VBL working in the editor but haven't succeeded. In the Edit -> Project Settings -> Quality menu / tab I enable the Sync to VBL button for all quality levels. Then, whatever the level of quality I choose for the editor, my frame rate is not synced to VBL ( I get about 250 fps ) and the tearing is terrible. I think I read somewhere I have to restart the editor for the changes to take effect. I did, but nothing refresh is still not synced to VBL.

Thanks for any suggestions.


PS : it does work when I build the game.

Sync to VBL will not work in the editor.
