I had the exact same issue. Went from an embraer190 to a330 and during my simulator training, I couldn't land the damn thing even if my life would depend on it. Imagine the muscles in my behind being tense when I had to do my first real life landing.
But it was a very descent landing. Writing that off to beginners luck, I was amazed the second one was the same. And so for all the landings I made the last year. Every now and then you get the occasional slightly bad one, but overall they are textbook.
And then I returned to the sim... Horrible again...
There is something wrong or missing in the/that sim. Maybe the seat of the pants feeling, the visual, whatever, but training xwind on a/that sim would be a waste of time for me.
