Input lag in PPSSPP

[griffinith]

I'm having the same issue while playing patapon 2 on my PC. There is very minor lag, and attempting to correct my input manually (hitting the button a fraction of a second prior to when I normally would) does work. I haven't tried DJ max yet, but this minimal lag is most likely going to have an impact on that game as well. It would be nice if there were a calibration feature that would allow users to correct the screen/input lag.
