Jon I presume this is to do with the fact that the sea is modelled as a few huge flat polys whose surfaces have a significant altitude change between the centres and the vertices. AFAIK this has not changed since the very early days of FG, but since we now all have graphics cards that are 2-3 orders of magnitude faster than when FG started, is now the time to increase the number of polys in the ocean? A reduction in the edge length of a factor of 3 would reduce the surface height variation by a factor of ~3, and increase the poly count in the ocean by a factor of 9, which I believe should be acceptable. Unfortunately, I have no idea where so start poking around in the codebase to do this though.

Regards -- Gérard It would be great if someone involved in this aspect of the code would be willing to dig in and figure out the problem before the final/official 0.9.11 release. My worry is that if there are not enough developers concerned about these sorts of problems, we will not have a very good release experience this time around. I do know that the ground intersection code is completely different between OSG and PLIB so something must have fallen through the cracks on the plib side.
