Even if you can see ground there is a posibility that in floating point arithmetics the test for that can fail. Also there could be a serious problem in this area. And why that freeze: It is somehow paranoid but it shows that there is something wrong. This could either be a roundoff problem, which should be handled in some way or it could be some other problem which should be handled in a different way. As long as it is not clear to me what is going on here. I am searching for that reason ...

In short: you are talking about race conditions. I don't think that this is a race condition since scenery loading is done in a seperate thread, but hanging that scenery into the scenegraph is done in the render thread which also does the FDM computations. > I get less than one fps display.
