Hi Kim, Chris,
I have a feeling that it might be to do with the number of variables in the shader rather than the MRT though as I think Umit had the same problem a while back.
That's probably the case, the 7 series cards support less uniform variables per shader, and if I remember well we were at the limit already in the ocean_scene shader, so perhaps the recent modifications (transparent ocean surface) put us over the limit.
As I said I don't have access to a 7 series card anymore (well I do but I'd have to swap it into a machine) so someone with one of those cards should really debug this.
