Hi and welcome to the forums. I personally have found 1/1 and 1/2 games in Vienna, Austria to be just as passive as in the US, but games in Budapest to be more aggressive than in Austria or the US.
However, the 2/2 PLO in Vienna I've played mostly has been as you described the 2/2 game at Spielbank. So I guess much like anything else with poker, it depends.
If you were playing NLHE, then you'll probably want to check out the LLNLHE forum here...
