I'm trying to use the v-sync in the game, as it suffer from awful tearing (at 60fps capped, the tearing keeps happening at the middle of the screen), but have had little luck doing so.

I tried forcing it in my graphic card drivers (Catalyst control center) for both UE4.exe and UnrealEngineLauncher.exe, it didn't work.

I also tried putting bUseVSync=True in GameUserSettings.ini but it seems to be overridden somewhere else.

I should mention that the second solution worked in an earlier build (can't remember which one), before using the official launcher.

Does anyone know how to use Vsync?
