Patapon 3 - UCUS98751

[Halaster]

Even getting past the first mission, I am having input lag on the game, which makes it pretty much unplayable since it is a music and timing based game.
Using a keyboard, or even using a PS3 controller there is always around a half a second of lag from when the button is pressed to when it registers in the game itself.

So if the drums are being hit for, Pata ...... Pata ...... Pata ...... Pon. For the Pon to register at the correct time I have to actually hit it RIGHT after the third Pata. And this is just at the start when trying to only do a correctly timed pon. Later on when doing Pata, and other buttons in time with the actual music its very difficult.
Pressing like this: Pata ...... Pata ...... Pata .Pon.....
Registers like this: Pata ...... Pata ...... Pata ...... Pon

The game itself never drops below 30fps, and I have no performance issues. Its only input lag that is the problem. Does anyone have any clue how to deal with this ?
The same issue is actually present in ppsspp as well.
