I don't have that problem at all when panning / moving the camera, though could certainly miss subtle differences. When in dragon form I don't get full detail on the ground when using the jetpack, obviously, but it is full quality as soon as I stop.
I have a similar system (3570K, HD7870, 16GB RAM, SSD for Windows and HDD for games).
Please email supportdc@larian.com, with a description of the problem and the report.zip file generated by the
Dragon Commander support tool.
