Chaders, I have AS12 (I think that I no longer use) compared to Opus, I just find Opus seems to replicated real weather almost exactly with minimal faffing about compared to AS.
I've not looked at direct comparisons between the two, but Opus also bumps you about to simulate turbulence with info it gets from the weather. Works quite well.
lol Shall I do it complete with the crazy folk hanging out of the Velux windows taking pics?
I'm sure I have G-max stored somewhere on the PC.
