@Groundhog:
I always have the lag it's just worse with vsync logically.
But In most games you wouldn t notice it much. Only some games need a very quick response.
I read some LCD screen have a lag in the display. Some poeple complained not being able to play games like Punch-Out on WII virtual consol and the screen was to blame.
I am using a Sony trinitron and Punch out is fine
