I've noticed there are a handful of ways to apply v-sync to a game:

  • In-game option
  • Catalyst Control Center
  • D3DOverrider
  • RadeonPro
  • Windows 7 Desktop Window Manager (via DWM.exe when gaming in Windowed-Fullscreen mode)

What are the functional/applicable differences between methods? I'm trying to determine which method might be preferable over another, or when you might want to use one method over another.

I've always used the in game options if available, then the CCC, then a 3rd party program like www.radeonpro.info if necessary.

My reasoning has been this:

For games that don't support anti-aliasing in game, you can force it through the CCC. However, this method is less efficient than if the game supported anti-aliasing natively.

I've always applied this same logic to vSync.

  • Unlike AA I'm not sure if it really matters nearly as much how you impliment V sync though, so I doubt CCC Vsync is much/any worse than in game. Could be wrong though, I've just never noticed a difference.

    @BenBrocka It's not how the vsync is implemented (there's only one implementation), it's how the game is/isn't programmed to mitigate the undesirable side-effects of vsync. If you use an external vsync, the game may not even know it's doing vsync and can't compensate; so built-in is always preferable, though won't always be better, if that makes sense?
