Is there any way I can simplify the mesh like the old days using
osgdem 1.2?
I'm a bit suprised that you are seeing a big difference, the
resolution and simplifcation technqiues used haven't changed since
1.0, the key difference was Jason Beverage's fixes to better sample
data extracted from GDAL, but I won't have expected to change things
too much on the final results.

I can confirm that , under windows , the mesh simplification is somehow
disabled, at least since a CVS version built around august.
I have also some problem shown in recent CVS:
osgdem seems to incorrectly shifts pages
(seems like there is a translation in texture sampling at different
resolution levels)
I see comparing DataSet.cpp that differencies reside in some code that
define a value xoffset.
I do not understand what is that code for, but the perceived shift seems
in x.
Can it be correlated with data that is erroneously perceived as geographic?
Is there a way to disable such offset?
Otherwise I can try to comment it out and see what happens.
Thanks in advance
