Non HD lag?

[eiirish]

Right so I use a non HD tv playing GH:WT, and I've never had a problem with lag. It's been like:
GH2 360: 0ms
GH3: 0ms
RB: 0ms
RB2: +35 / +20 (Apperently this is as 0ms in RB, no idea why but it works great)

And so now I'm playing GH:WT and it's definitively something wrong :/. It's not the engine I'm used to the RB one. Feels like I hit everything before the sound, but it can't be my tv. So is there anything I can do?
